! It is highly recommended that suitable tools are utilised for the

correct preparation on Paper Cables

! Use a propane gas torch with a soft flame
! Avoid a pencil like blue flame which is caused by unregulated supply
! Keep the flame on the move to ensure even shrinkage of all the

materials and also helps to reduce scorching

! Ensure that all components are kept clean and grease free during

installation

! Allow to cool before applying any mechanical strain

Improved Clearance/Cross Core Kit

A kit is available which converts Paper Belted Cable into a Screened Cable which enables
greater clearances between Cores and allows a Core Cross if required.

Table 1).

Expose the armour wires to 50mm for
plumbed connections. De-grease and
clean the Lead or Corrugated Aluminium

Expose the Lead or Aluminium Sheath to
a dimension of 250mm from the outer
Cable Sheath.

Unwind the Black Carbon Paper and
remove to a binder positioned 5mm from
the Metal Sheath cut.

Using a further binder, remove the Belt
Papers to 25mm from the Metal Sheath
cut.

CLEAR SHRINK

SLEEVES

Fitting the Clear Shrink Sleeves

With a clean dry cloth, carefully remove
any Grease from the Cores.

Position the Clear Shrink Sleeves over
each Core approx 50mm up from the
Cable Crutch. With a suitable heat sourse,
shrink the end’s of the Sleeves for about
50mm, before fully shrinking, rotate the
Sleeves and push down into the Crutch.
Note: E

nsure there are no air voids and
the Sleeves are wrinkle free, also note
that excessive heat may dry out and
damage the Paper Insulation.

Fitting the Stress Control Tubes

50mm

STRESS

CONTROL

TUBE

Position the Stress Control Tubes onto the
Cores at a distance of 50mm up from the
Metal Sheath Cut.

Shrink the Tubes one at a time, starting
from the bottom working upwards. Ensure
that the Tubes are evenly shrunk and
aligned.

Cable Crutch Preparation

MASTIC

CRUTCH

WEDGE

Remove the Grey Mastic Crutch Wedge
from its container and insert well down
into the Cable Crutch so that any Air gaps
are eliminated.

10mm

10mm

LEAD OR

CAS SHEATH

With tension, wrap the Grey Mastic Tape
around the Crutch area and overlap the
Stress Control Tubes and Lead or
Aluminium Sheath by approx 10mm.

Note:- Ensure that the space between the
Bell of the Lead Sheath and the entire
area between the Cores is fully covered by
the Mastic tape to eliminate Air Voids.

With a suitable solvent, clean the Metal
Sheath before proceeding.

3. General Cable Preparation

Installing the Breakout Boot

SEMI-CONDUCTIVE

BREAKOUT BOOT

X

Slide the 3 Leg Semi-Conductive Breakout
Boot down the Cores and press firmly
down into the Crutch.

The Legs of the Boot should be in contact
with the Stress Control Tubes and the
Skirt should cover the Grey Mastic Tape
and make contact with the Lead or
Aluminium Sheath.

Shrink the Boot from the centre to one
end at a time. The Boot may need to be
held in place during installation.

4. Installing Cable Lugs

Allowing for dimension X (Lug Barrel +
5mm), cut the Cores to suit the fixing
point on the equipment being used.

L + 200mm

Measure a distance of X (See Table 1)
back from the end of each Core and
remove Insulation.

With a suitable tool, install Cable Lugs
ensuring that any sharp points are
removed.

Note:- Where Mechanical Connectors are
to be used, user should check that the
Core Tubes are able to slide over prior to
fitting.

5. Installing Anti-Track Tube

Preheat each Cable Lug and wrap two
layers of Red Sealant Tape over the Lug
Barrel extending onto the Insulation by
approx 10mm.

Also apply a turn of Red Sealant around
the tops of the Breakout Boot fingers.

Position the Anti-Track Core Tubes so that
they cover the Fingers of the Breakout
Boot and the Barrels of the Lugs.

Shrink the Tubes starting from the bottom
towards the top. Keep the flame on the
move to ensure an even wall thickness
and that the Tubes are wrinkle free. Allow
to cool to hand hot and trim at the Lug
end with a sharp knife if necessary.

Note:- Bushing protection boots will be
required for the majority of installations.

6. Installation Of Rain Sheds

r = SEE d DIMENSION

IN TABLE 2

A Strain Relief Shed is required for
Outdoor Terminations. This should be
fitted first by positioning it as low down as
possible but above the end of the
Breakout Fingers (Approx 60mm).

STRAIN RELIEF

SHED

Continue to install the appropriate number
of Rain Sheds in accordance with the
details shown in Table 3.

Table 3

All subsequent sheds should be fitted at a
distance of 80mm from edge to edge.

Note:- It is advisable not to position rain
sheds at the top of stress control tubes,
re-position if necessary.

If a termination is to be mounted for
connection above the equipment i.e in the
reverse position, sheds should be installed
through 180 as shown.

7. Core Crossing

Screened Cable

If the Cores on a Paper Screened Cable
have to be crossed, ensure that the cross
takes place within the screened area
below the Stress Control Tubes.

Belted Cable

Core crossing on Belted construction is
not recommended unless the minimum
clearances are achieved (See Table 2).

Note:- Core Crossing/Improved Clearance
kits utilising Heatshrink Conductive
Tubings can be supplied if requested.
