INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Pre-Installation Requirements

This manual is a guide to the Installation, Operation and Maintenance of the ERITECH SYSTEM 3000 Lightning Protection System.

It assumes that the system to be installed has been designed by an authorized ERICO representative. The system design will include:

Grounding system design - a configuration should be designed as a result of soil resistivity analysis.

t Downconductor routes - chosen to

avoid other services, maintain minimum bending radii and minimize downconductor run length.

t Downconductor securing requirements. t Terminal types - operating environment. t CAD analysis design software which

determines terminal placement, mast & height requirements as well as protection level calculation.

All of the above are recommended for a successful installation. If there is any doubt about any of the points mentioned, please contact ERICO or your nearest Distributor for clarification.

Only attempt to install the ERITECH SYSTEM 3000 during storm-free periods.

Figure 1.

www.erico.com

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

The recommended order of installation is as follows:

1. Full installation of the grounding system.

2. Full installation of the downconductor.

3. Termination of the downconductor to the grounding system.

4. Upper termination of the downconductor (may already have been completed by ERICO) and connection to the ERITECH

5. Termination of bonding cable from upper termination to structure (if required).

6. Raise mast into position and secure.

DYNASPHERE air terminal.

Grounding Systems

The grounding system is critical to the integrity of any lightning protection installation and should include consideration of:

t Local Standards compliance

(IEC 61024-1, BS 6551, AS1768-1991,

780, C22.1-98, NEC® etc.)

NFPA

t Available space / location. t Natural soil conditions - resistivity of

soil, soil moisture content, soil temperature range, etc.

t Location of underground services -

Power, Communications, Fuel, Gas, Water, etc.

t Corrosive environments, ie: salt

water, acid / alkaline contaminated ground mass.

t Use of suitable grounding rods such

as ERITECH

rods.

t Minimization of risk to personnel.

Contact an ERICO office or Distributor if you require further advice on grounding systems.

Downconductors

The ERITECH® ERICORE downconductor or other recommended downconductor should have been selected during the design stage, as should the route, length and any preterminations of the downconductor.

Re-check intended route of downconductor immediately prior to installation to ensure that:

t There are no structural changes or

additions that may effect the initial design.

t Most direct route possible to the

grounding system with minimal number of bends and as flush with the structure as possible.

t Minimum bending radii maintained

(500 mm, 20 in.).

t Parallel routing with other services -

minimum separation = 2 m (80 in.).

t Attachment to the structure is at a

maximum of every 1 m (40 in.) for the top 10% of the downconductor route and 2 m (80 in.) from then on.

t Pipe installations follow the instructions

given on page 17.

www.erico.com

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Re-check:

t Securing of downconductor - saddles,

cable ties, beam clamps, cable hangers, etc, are appropriate.

t Method of cable installation, ie. cable

upper terminated on the outside of the drum - to be rolled off from the base of the structure, or cable upper terminated on the inside of the drum - to be rolled off from the top of the structure, (refer Figure 6 on page 15).

t The outer sheath of the downconductor

must be electrically bonded to a conductive structural point within 5 m (17 ft) of the upper termination kit.

Structural Bonding Braid & Conductive Structural Points

When installing the upper end of the downconductor on a masonry

structure (concrete panels, brick, etc), the downconductor should be secured directly to the structural steel work. In addition, the bonding cable (supplied in the termination kit) must be connected via

(8 AWG) insulated copper cable to

6 mm the nearest conductive structural point. This point should be where the downconductor first comes into contact with the structure and may be either structural steel work or the reinforcing within concrete panels or slabs.

See Pages 18 to 24, figures 10-17 for more details and diagrams.

Lightning Event Counters

The Lightning Event Counter (LEC IV) is a device for registering and recording the number of strikes that the ERITECH SYSTEM 3000 has intercepted. The design of this counter allows many installation alternatives on the downconductor as discussed in later text. Also, see Specifications on page 60.

The following should be considered prior to installation of the Lightning Event Counter:

t It is advisable to locate the LEC IV in

a secure area that is not prone to contact with moving objects, theft, or vandalism.

t If the LEC IV is to be encased in an

additional enclosure, ensure that it is mounted to enable easy access to the display, (see figure 32 on page 48).

ERITECH® DYNASPHERE Terminals

The ERITECH® DYNASPHERE is the air

terminal of the ERITECH SYSTEM 3000.

Ensure that the appropriate air terminal has been provided.

It is recommended that this point be determined prior to the installation to allow for any site work or equipment that may be required prior to the installation.

The 6 mm and the length of the cable will need to be determined and obtained before commencing the installation.

(8 AWG) cable is not supplied

Suitable for use in:

t General purpose applications t High temperature environments t Corrosive environments (salt or acid

atmosphere)

Ground Resistance Lowering Compounds

Ground enhancing compounds, (such as GEM) are recommended and supplied when the existing soil mass has a high resistivity.

These compounds can be used to increase the total surface area of grounding conductors, resistance / impedance.

Compounds may require water and a mixing container.

thereby reducing the ground

When applying these compounds, be sure to take necessary handling precautions as advised by the product instructions, and ensure that the directions for use are followed correctly.

Insulation of Grounding Systems

In some installations, it may be necessary to insulate part of the ground system from an area of the surface, for the purposes of safety or isolation, (pedestrian walkways, proximity to other services, etc.). In this situation, it is recommended that a minimum of 70 mm copper cable is run in PVC conduit to the connection point (start) of the intended ground system. This conduit should be at a depth of at least 600 mm (24 in.), or greater if required, to ensure that it is below the frost line to the start of the intended ground system.

Another possible design method for reducing surface step-potentials may be to insulate the ground system for the first few meters of depth from the surface. This is done by isolating the initial injection point of the downconductor from the surface of the ground mass by running it through PVC conduit to the required depth before exposing it to the ground mass.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Downconductors

Depending on site requirements, the downconductor(s) may have their upper terminations completed at a pre-specified end of the cable by ERICO before shipment. These terminations will be protected by a short length of flexible PVC tube.

It is VERY IMPORTANT that when removing these tubes, they are not removed with a knife or cut in any way as this will damage the outer layer of the termination. It is suggested that the tape and cover are best removed by hand. (See figure 6)

All ERITECH® purpose-designed downconductors have a semi-conductive outer sheath which is approximately 2 mm (0.08 in.) thick. Rough or careless handling of the downconductor can damage this sheath and compromise its performance.

Downconductor Hauling

Locate the downconductor cable drum at the appropriate location, (refer to figure 6).

When hauling the downconductor, use the following guide points:

t Ensure that the cable drum, if supplied, is

in a serviceable condition.

t If the downconductor has been upper

terminated on the outside of the drum, then the downconductor must be hauled

off the drum from the ground.

t If the downconductor has been upper

terminated on the inside of the drum, then the drum must be at or near the

of the structure, so that the down-

can be unwound from the

t When using slings or ropes to haul

downconductors, use MULTIPLE hitches around the cable.

t DO NOT sling from the termination

coupling or cold-shrink section of the terminated downconductor.

t DO NOT use cable stockings over

TERMINATED downconductor ends.

t Protect the downconductor from

abrasion and tearing when hauling over rough surfaces, at all times, especially around corners or through penetrations.

Penetrations

Before routing the downconductor through any penetrations, ensure that:

t If un-terminated, a minimum hole

diameter of 50 mm (2 in.) is provided.

t If terminated, a minimum hole diameter

of 60 mm (2

⁄8 in.) is provided.

t Enough physical protection (conduit

or similar) is provided to stop the downconductor from being damaged when being fed through the penetration.

t When feeding the upper termination

of the downconductor through any penetrations, the termination sheds (flanges) should be temporarily wrapped in insulation tape to reduce their diameter and protect them against abrasion. This is very important as the cold-shrink tubes are susceptible to tearing if nicked or scuffed.

If either side of the penetration requires environmental protection ie: waterproofing, air-con pressure seal, etc., use a suitable sealant or deck sealing gland.

Routing

The route taken by the downconductor is very important and must follow these rules:

t Carefully survey the intended route

of the downconductor immediately prior to the installation to check for any alterations that may effect the original design, ie: structural changes, new antenna or mast installations, air conditioning towers or ducting, etc.

t Use the most direct route practical to

minimize the downconductor length.

t To minimize the risk of side-flash,

DO NOT route the downconductor back beside itself after change of direction, ie: 180º.

t Minimize number of bends. t Minimize strain on the downconductor

during installation.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

t To seat the terminal correctly in the top

of the FRP mast, any cable slack will have to be removed from the mast while also minimizing any stress on the upper termination sheds (flanges) by twisting the FRP mast against the terminal for at least one turn.

If the downconductor is damaged during installation, it must be checked by an ERICO

representative to see if the damage will effect its safe operation.

Securing the Downconductor

Securing of the downconductor not only provides a mechanical attachment to the

structure, but also an Electrostatic connection to the structure via the semiconductive outer sheath of the downconductor cable.

It is important that the downconductor is both physically and electrically secured to the entire length of the structure to relieve both physical and electrical stresses along the downconductors’ length.

The electrical bonding of the downconductor is especially important for at least the first 10% of the downconductor route from the upper termination, and for this reason the downconductor must be secured at least every 1 m (40 in.).

ERITECH® brand of saddles and conductive clamps are

recommended for the purpose of securing the downconductor. These have been specifically designed and manufactured to mechanically secure and electrically bond the ERITECH

ERICORE to the structure, while minimizing stress points on the cable.

Use of a brand of saddles other than ERITECH can compromise the outer sheath, creating high stress points which can lead to flashover, (see figure 10).

Use ERITECH clamps only

Figure 10: Detail shows the need to use ERITECH Clamps.

To help ensure that the upper end of the downconductor can be adequately electrically bonded to the structure, a Structure Bonding Braid has been provided at the base of the upper termination of the downconductor. This braid is a 75 mm (3 in.) tail which exits from under the termination coldshrink and is connector to allow connection (8 AWG) copper cable (as mentioned in the following text). This must be connected to a conductive structural point to relieve the electrical stresses on the downconductor and masonry surfaces.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

After routing the downconductor, it must be kept in constant physical contact with the structure via conduc

tive fixings as follows:

t The top 10% of the downconductor

from the terminal must be secured at least every 1 m (40 in.). This includes metallic mast sections.

t The lower 90% of the downconductor

must be secured at least every 2 m (80 in.).

t This includes routing inside any type of

conductive pipe or conduit, (see Fig. 17).

t When mechanical fastening of the

cable every 2 m (80 in) is not possible, a maximum unsupported length of 35 m (114 ft) is allowed as long as the installation adheres to the electrical bonding requirements (see use of cable ties in figure 17).

When using metallic lower sections of mast (ie: aluminum), then the downconductor MUST be secured with ERITECH of saddles to the mast at 1 m (40 in.) intervals (max.). The mast in turn must be electrically bonded to the nearest conductive structural point. In this case, the structure bonding braid must connect to the inline coupling, (see Fig. 14).

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Refer to Figure 18 for the following instructions (1 to 10).

1. With the hacksaw (or appropriate cutters), cut the downconductor cable to length, leaving enough cable to be able to easily and directly route it to the ground termination.

2. At a distance of 100 mm (4 in.) from the end of the cable, carefully cut a shallow notch into the black outer insulation, no deeper than 1 mm, (

⁄64 in.). Using the insulation cutting tool, cut around the circumference of the black outer insulation until the copper screen underneath is exposed.

Important! The insulation cutting tool uses friction to cut into the sheath and is less likely to damage the layers underneath than using a knife.

3. Use a knife to carefully cut along the 100 mm (4 in.) length of black outer insulation to a depth of no more than 1 mm. (

⁄64 in.). Be careful not to cut too deeply so that the copper layer underneath is not exposed or damaged. Starting from the end of the cable, carefully remove the outer insulation and discard.

4. Carefully clean up the insulation friction cut, removing any burrs for a neat finish.

5. Fit the roll spring 15 mm (

⁄8 in.) from the end of the outer insulation over the exposed copper tape (roll spring supplied with upper termination kit).

6. Remove the copper tape up to the roll spring (exposing black triple extrusion layers) by unrolling, then tearing the tape up and back over the edge of the roll spring at about a 45º angle. If necessary, cut about 6 mm (

⁄4 in.) of the copper tape up against the roll spring with a knife and then tear over the spring.

7. Wrap one end of the 2.5 mm 105 mm (12 AWG x 4

⁄8 in.) bare copper

wire (supplied with the kit) around the hose clamp, then fix the hose clamp over the exposed copper screen of the downconductor and tighten with a screwdriver.

8. At 85 mm (3

⁄8 in.) from the end of the cable, carefully cut around the circumference of the black triple extrusion layers with a knife, then, from the first cut, along the length of the insulation to the end of the cable. Remove the layers and discard.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

The Insulation Cutting Tool uses friction to cut into the sheath and is less likely under

to damage the layers

neath than using a knife. When the instructions call for the knife to be used, be sure not to cut any deeper than instructed.

If the instructions are not followed correctly, or if any of the insulation layers or the copper foil are incorrectly cut, then the integrity of the lightning protection is affected.

Refer to Figure 21 on page 36 for the following instructions (1 to 11).

1. At a distance of 600 mm (23

⁄8 in.) from the end of the cable, carefully cut a shallow notch into the black outer insulation no deeper than 1 mm, (

⁄64 in.). Then, using the insulation cutting tool, cut around the circumference of the black outer insulation until the copper screen underneath is exposed, (see photo 3).

2. Using a knife, carefully cut the outer insulation of the cable to a depth of no more than 1 mm ( 600 mm (23

⁄64 in.), for the full

⁄8 in.), in the direction of the end of the cable. Be sure not to cut so deep as to expose or damage the copper layer underneath. Starting from the end of the cable, carefully remove the outer insulation and discard.

Photo 3: Use of the insulation cutting tool to cut the insulation without damaging the layers beneath.

3. Carefully clean up the friction cut, removing any burrs for a neat finish.

4. Fit the roll spring 20 mm (

⁄8 in.) from the end of the outer insulation over the exposed copper tape.

5. From the end of the cable, remove the copper tape up to the roll spring, exposing the black semi-conductive material by unrolling, then tearing the tape up and back over the edge of the roll spring at about a 45˚ angle. (If necessary, carefully cut about 6 mm of the copper tape up against the roll spring with a knife and then tear over the spring).

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

6. Carefully remove the roll spring, then tape up the last 6 mm (

⁄4 in.) of the copper tape with a piece of PVC tape, to stop further unravelling.

7. Clean and degrease the outer sheath for a distance of 100 mm (4 in.) from the cut position. Using slight tension, wrap one layer of sealant tape (red) around the black outer insulation with a small overlap of 5 mm (

⁄5 in.) over the copper tape

screen, (see photo 5).

8. Place the structure bond braid over the cable so that it sits over the copper screen and up against the sealant tape (red). Ensure that the braid loops are tight around the copper screen. Tape the bond braid into place with PVC tape, (see photo 6). (Ultimately, this braid may require electrical bonding to the structure.)

9. At a distance 70 mm (2

⁄4 in.) from the end of the cable, carefully cut a notch in triple layered insulation no deeper than

⁄64 in.). Then using the insulation-

1 mm ( cutting tool, cut around the circumference of the triple layered insulation until the copper underneath is exposed.

16. Rewrap the outer double layer of copper tape into place over the copper strands. Push the compression ring back up over the wrapped copper strands and up against the cone, (see figure 23).

17. Fit the main coupling piece from the coupling set carefully over the end of the cable ensuring the cable is pushed up as far as it will go into the coupling. Ensure the copper strands are kept in place and order. Screw the compression nut into the coupling piece and tighten, using the correct size spanners / wrenches.

18. At a distance of 100 mm (4 in.) from the end of the cable, wrap one half-lapped layer of semi-conductive tape around the triple layer insulation with an overlap towards the copper tape / copper strand center conductor up to, but not over, the compression coupling.

19. Loosening Termination

This operation is vital to the simple installation of the product.

There are two terminations in this kit, (one with three sheds, the other with five). Loosen both in the manner shown on page 33. Install the five shed termination first.

Hold the termination in one hand and the holdout in the other. Gripping firmly, twist the termination and holdout in opposite directions. Repeat twisting the termination and holdout, moving the hand in short increments up the termination until the entire termination is felt to move on the holdout. Slide the termination until it lines up with the end of the holdout tube as shown. Note: Take care not to slide the termination off the end of the holdout. Stop the termination about 6 mm (

⁄4 in) from the end of

the holdout.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

20. Installing the termination.

Position the holdout over the cable until it meets the jacket cutback. Twist the termination and slowly push it to the end of the holdout.

Slide the termination off the holdout with a twisting motion, holding the termination that is on the holdout in one hand and pulling the holdout with the other.

Note: Do NOT stretch the termination.

Do NOT hold the termination that is partially installed and attempt to pull the remaining termination off the holdout, as this will stretch the termination and generate an improperly installed termination if not repositioned.

www.erico.com

Using the pull tabs, pull the flip-back portion away from the main termination, at the same time working the first two fingers of each hand between the flip-back and main termination. Pull the stretched out flip-back over the cable jacket and sealant.

Make sure the termination length is in accordance with the dimensions shown.

The coupling must be tightened using spanners / wrenches, as tightning by hands will not be adequate.

22. Using the roll of silicone tape (grey), overwrap half layers from 20 mm ( the end of the coldshrink to 30 mm (1

⁄4 in.) over

⁄8 in.) over the coupling so that it covers the joint between the main coupling and compression nut, (refer to figure 24 on page 39).

Wrap with moderate tension (10 to 100% stretch). Apply one final layer with no stretch. Press down, to avoid the end lifting before fusion of the tape takes place.

The finished termination must be protected against any abrasion and sharp edges during transport or installation, as the coldshrink tubes are susceptible to ripping or tearing if nicked or scuffed.

23. The structure bonding braid MUST be electrically connected via a 6 mm

(8 AWG) length of insulated copper cable to the specified conductive structural point, as

described in the ERITECH® SYSTEM 3000 Installation, Operation & Maintenance Manual.

Connecting the ERITECH

terminal, then screw the terminal all the way onto the termination coupling thread. Replace the lock screw back into position so that it locks the thread into place and will stop the terminal from unscrewing.

25. Carefully pull the downconductor (and structure bonding cable) back down through the FRP mast so that the terminal base sits correctly in the top of the mast. Twist the FRP mast at least one complete turn at the base of the terminal to remove any stress on the termination sheds (flanges) and to seat the terminal correctly.

Terminals and Masts

Terminals

Once the terminal has been checked and found to be in an acceptable condition for installation, it can be attached to the terminated downconductor as shown in the Upper Termination instructions on page 37.

Please note, the serial number of each unit will have been recorded in the Certificate Of Compliance (inside back cover) in this manual.

Masts

The selected mast configuration chosen must:

Elevate the terminal to the required

height as determined by the design process (minimum height of 3 m (10 ft.) above the highest point of the structure).

Include a minimum of 2 m (80 in.) of insulated mast material (FRP) immediately below the air terminal.

Be suitably rated for local weather conditions. It is advisable that guidance from a local civil engineer be sought.

Be securely attached to the selected mounting point(s).

Be guyed if applicable.

If the lower section of the mast is conductive, ie. aluminum or galvanized iron; then:

secured to the mast at 1 m (40 in.) intervals (max.).

Three basic types of mast configuration include:

Guyed

Single length guyed - one section of FRP (Fiberglass Reinforced Plastic) mast material guyed at the top.

Double length guyed - two sections of

mast material, usually aluminum lower and FRP upper, guyed between the two sections and at the top.

Cantilevered Used in situations where it is more practical

to mount without a base, eg: radio towers.

t At least one third of the lower mast

should be secured against the structure.

t Cantilevered masts can either be free

standing or guyed for extra stability.

Freestanding Often used where the terminal, down-

conductor and grounding system are isolated from volatile areas by installing the ERITECH away from those areas.

Before the installation of the mast, ensure that:

The free standing mast is supplied with

an appropriate spigot, suitable for either internal or external mounting of the FRP mast.

The downconductor is to be routed

internally or externally.

Provision is made for external or internal

If an aluminum mast and base are used and can not be directly attached to the structural steel work, or are anchored to a concrete roof, then they need to be directly electrically bonded to the closest structural steel work or conductive structural point. Refer to page 20.

Mast Couplings and Guying Points

There are two different methods of coupling two sections of mast:

1. The U-Bolt set, which uses two stainless steel U-bolts to clamp the two sections of mast together, (see figure 28).

2. The Inline Coupling is designed to fit between the upper and lower sections of the masts and also provides three guying anchor points, and, a downconductor exit point if required. The maximum mast diameter that the Inline Coupling is able to clamp onto is 70 mm

⁄8 in.) OD.

On both the U-Bolts and Inline Couplings, the nuts must not be tightened to any more than 55kg/cm (45 in.lb).

Additional guying is required at the top of 4.6 m

Raising of Mast

When ready to raise the mast, check the following:

Guys to the inline coupling, guying ring

or other mast anchor points are properly secured.

Ensure the guys are not twisted, kinked

or damaged in any way.

Ensure that each guy can be easily

secured at the base when the mast has been raised.

Turnbuckles or rigging screws are recommended at the base anchor points of the guys to enable easy vertical alignment of the mast and correct tensioning of the guys. If using turn-buckles, ensure that they are wired securely with nichrome wire.

Using conductive guying, such as stainless steel, is acceptable as long as it is NOT used for guying to the top of sections of insulated FRP mast. Guying to the top of an aluminum section of mast is acceptable.

"Live" Side

Remember to always Plan the Lift before attempting it.

If the mast is to be raised by hand, ensure that it can be safely and easily managed manually.

It is recommended that the use of a crane or other suitable equipment be used for anything over 6 m (20 ft.) in height, or for hazardous area installations such as high elevations (towers).

To minimize the possibility of the mast becoming bent or damaged, it is very important to keep the mast straight during the lift.

Ensure that:

t There are no overhead AC

power lines.

t There is nothing overhead that will

obstruct the lift.

t There is enough man-power available to

safely conduct the lift.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Long Lengths of ERITECH® ERICORE

Downconductor

Most installations can be conducted with a single ERITECH

ERICORE downconductor cable as described earlier in this manual. However, where the installation involves a long single length of ERITECH

ERICORE cable, additional measures may need to be taken to help ensure that the voltage build up on the cable during a lightning strike will not be excessive.

Proposed ERITECH® ERICORE length

Determine the thunderday level at

the proposed installation site.

Before considering these measures, it needs to be determined if the cable is too long to run in a single uninterrupted length. The flowchart in Figure 33 allows this to be determined. Starting with the proposed ERITECH

ERICORE length as indicated in the LPSD design, follow the chart to the appropriate outcome. If a single length of ERITECH ERICORE is acceptable, no further consideration is required.

Figure 33: Determination of maximum single ERITECH ERICORE length.

www.erico.com

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

However, if the result indicates that additional measures are required, then a single uninterrupted length of ERITECH

ERICORE cannot be run.

Although the flowchart allows lengths of up to 87 m, ideally lengths should be limited to 70 m to avoid any likelihood of problems.

When determining the apparent length of ERITECH

ERICORE conductor required in a particular situation it is prudent to make the connection to the ground system at the first available opportunity. The practice of running ERITECH ERICORE for long horizontal lengths at the ground level to reach a designated earth point is discouraged. Instead a lower termination should be made to a suitable earthing point upon reaching the ground or basement level, then a separate length of conventional grounding bonding conductor run to other earthing points as required.

In the case of installations exceeding the maximum single ERITECH

ERICORE cable length, the advice of the ERICO application engineering group should be sought. The following information on the techniques used is intended as a guide for installers and to provide background information.

Note: If the number of thunderdays for the proposed installation site is not known, but the ground flash density is known, this value can be converted to thunderdays using the following table. This resulting value can then be used in the figure 33.

When additional measures are required, there are two basic approaches to reducing the otherwise unacceptable voltage rise that would occur on the cable:

t3VOBTJOHMF&3*5&$)

These methods are explained as follows.

Parallel ERITECH® ERICORE cables

Running two or more parallel cables reduces the voltage rise on each cable by reducing the current magnitude flowing in each cable. For example, if three cables were run in parallel, each cable could be three times the single length. In practice, however, this technique is generally only economically viable when running two cable sections in parallel. ERICO has developed a special hardware arrangement to allow this to occur, as illustrated in Figure 34.

ERITECH® ERICORE Cable and Upper Terminations

ERICORE

The dual coupling termination allows the ERITECH connect to two ERITECH

DYNASPHERE air terminal to

ERICORE cables, each complete with upper terminations and FRP masts. All the rules that normally apply to a single ERITECH ERICORE arrangement apply to these two cables and mast arrangement.

A typical mast arrangement is shown in Figure 35. The normal u-bolts are used to fix the FRP masts to the aluminum mast, and the conductive saddles are used to fix the ERITECH

ERICORE to the mast at the normal interval of at least every 1 meter (40 in.). Note that the center mast and the two FRP sections will not be completely in line when the FRP masts are correctly spaced.

Depending on the mast height required, either the 2 meter, or the 4.6 meter, FRP mast may be used.

These items are only included in item ‘TERMDUALCOUP’, remaining items are shown for field assembly purposes only.

IMPORTANT – To maintain the necessary clearance between the ERITECH

Series connected ERITECH® ERICORE cable sections

As an alternative to running twin ERITECH ERICORE conductors, a single ERITECH ERICORE cable can be run, but it is broken into several sections, none of which exceeds the cable breakdown voltage. This is done by periodically connecting the cable to a conductive structural point (see Figure 37).

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

The lower end of the upper cable section is fitted with a lower termination, and the upper end of the lower cable section is fitted with an upper termination. The lower termination inherently has a lug termination, but the upper termination needs to be fitted with a bonding termination (ERICORE/UTSP) and lug (termlugcoup) to allow it to be lugged. Each of these two lugged terminations must be electrically bolted together and to a suitable conductive structural point.

In some installations, both lugs can be directly connected to a suitable conductive structural point, but in some installations it will be more convenient to connect both lugs to a small busbar, and have this busbar connected to a suitable nearby conductive structural point. Note that the conductor used in this case must be a minimum of 16 mm

(4 AWG) and should not exceed 5 m (200 in) in length. A suitable conductive structural point may be either structural steel work or the reinforcing within concrete panels or slabs.

These joints should not be exposed to the weather and are usually located in a service shaft. Very tall buildings will have a number of connection points depending on their height.

Details of where to provide the joint will be provided by the ERICO application engineers, after consideration of the building details.

Practical examples for Long

When to use a twin ERITECH

ERICORE arrangement or a series connected arrangement depends on the particular circumstance. The following examples give typical guidance.

Telecom Towers

Most towers would be less than 70 m, or so, in height so that a single ERITECH ERICORE downconductor would suffice. However, where the tower is over the maximum single length but less than twice the maximum single length (typically 70 m (230 ft) to 140 m (460 ft) in height), it is preferable to run twin ERITECH

ERICORE downconductors. These conductors should ideally run down opposite legs of the tower and each connect into the ring earth at the base of the tower.

Alternatively, and less preferably, a single upper section of typical length 70 m (230 ft) could be run from the top of the tower to a point lower down on the tower, then bonded to the tower using a waterproofed lower termination. A conventional lightning downconductor could be run from this point down to the base of the

tower. This arrangement helps ensure that the lightning current bypasses the sensitive tower mounted electronics mounted in the antennas on the top half of the tower.

Buildings

Buildings less than 70 m (230 ft), or so, in height are served by a single ERITECH ERICORE downconductor.

Buildings of height over the maximum single length but less than twice the maximum single length (typically 70 m (230 ft) to 140 m (460 ft) in height) may be installed with either twin ERITECH ERICORE down-conductors, or a series connection in the service shaft.

Buildings of height greater than twice the maximum single length (typically greater than 140 m (460 ft) in height) need to use the series connection method. The ERICO application engineering group will determine the allowable lengths of the lower cable sections, which may be able to be longer than the upper length, and in some cases, the lower sections may be conventional downconductor.
