Hubbell IS628BT Installation & Operating Instructions Manual

Important: Read these instructions thoroughly before operating the system. Be sure that the

connectors are rated for the intended energized use. (See Hubbell catalog (C7) for selecting the correct
mating product.) For additional information, you may want to reference IEEE Std. 1816, Guide for
Preparation Techniques of Extruded Dielectric, Shielded Cables Rated 2.5 kV through 46 kV and the
Installation of Mating Accessories.

Note: For kits with reducing taps or modular splice kits, please refer to supplemental instructions

packaged with those components.

STEP 6. Connection

A. Clean and lubricate the T-Body, apparatus
bushing, and insulating plug interfaces with supplied
lubricant.

B. Hand tighten the loose stud into the insulating
plug two or three turns if the mating interface is not
equipped with one.

C. Align the T-Body to the apparatus bushing
interface. Insert the insulating bushing and hand
tighten to prevent cross-threading. Tighten the
insulating bushing to 50-60 ft-lbs of torque using a
1” socket and a torque wrench. (See Figure 11.)

D. Clean and lubricate the test point cap and snap
it onto the insulating bushing.

STEP 7. Grounding

A. Attach a #14 AWG copper wire (or equivalent)
to the grounding eye of the T-body. Twist the wire
at least two turns to ensure it is secured properly.
Attach the free end to system ground.

B. Twist the neutral wires into a braid and connect
to system ground with appropriate connector. Make

sure to provide sucient slack in ground braid to

provide for future operation. (See Figure 12.)

DESCRIPTION

The Hubbell 600 A Deadbreak T-body Connectors
are designed to terminate underground cables
and provide a connection to transformers,
switches, sectionalizing cabinets, and a means
to create modular splices. These components
conform to all requirements of IEEE Std. 386 and
are designed to mate with all other manufacturer’s
products that also conform to IEEE Std. 386,
Interface 11.

! CAUTION

The equipment covered by these instructions should be installed, operated and serviced only by competent
personnel familiar with safety practices. This instruction is written for such personnel and is not intended as a
substitute for adequate training and experience in safe procedures for this type of equipment.

! DANGER

Do not touch or move energized product by hand. Failure to follow this instruction may result in serious or fatal
injury, as well as damage to the product.

These instructions do not purport to cover all details or variations in equipment nor to provide for every possible contingency to be met in connection with installation,
operation or maintenance. Should further information be desired or should particular problems arise which are not covered sufficiently for the purchaser’s purposes, the
matter should be referred to Hubbell Power Systems, Inc.

! CAUTION

Optional Capacitive Test Point- When making voltage measurements, the area of and around the voltage test
point must be dry and free of contaminants. The voltage test point is not intended for actual voltage measure­ments or phasing operations and has no direct connection to the conductor. It uses an impedance capaci­tance tap and only voltage indicating instruments designed for this application to establish the presence of
voltage should be used. A voltage reading will indicate the presence of voltage, but a reading of no voltage is

not sucient to establish a de-energized circuit before touching the connector. Other procedures should be

implemented to establish a de-energized circuit.

Installation & Operating

Instructions

NOTES

• Check contents of box to ensure that it is complete and components are NOT damaged.

• A shield adaptor may be required for certain power cables.

CONNECTION

CABLE PREPARATION

NOTE:

These instructions will cover concentric neutral cable applications so please refer to cutback

instructions from shield adapter kits for steps on how to prepare other typers of underground power cables.

STEP 1. Train & Remove Jacket

A. Train the cable into the nal assembled position

using the natural bending of the cable. Allow

sucient slack in the cable to move the T-body at

least a foot from the apparatus bushing.

B. To provide sucient length of concentric neutral

conductor for grounding after installation, measure
14-1/2” down the cable from the centerline of the
bushing interface and remove the jacket to this
distance. Care should be taken not to damage neutral
wires. (See Figure 1.)

C. Bend neutral wires out of the way.
(See Figure 2.)

STEP 2. Cable Preparation

A. Cut the excess cable o square and 1-3/4” below

the centerline of the bushing. (See Figure 3.)

B. Remove the insulation shield 9-3/4” back from the
end of the cable. Cut squarely, making sure not to
nick or damage the insulation.

C. Apply two layers of PVC onto the insulation shield
10-3/4” back from the end of the cable. This will
serve as a temporary marker for locating the cable
adapter. (See Figure 4.)

D. Remove insulation to expose 4-1/2” bare
conductor. Cut squarely making sure not to cut or
nick the conductor. (See Figure 5.)

E. Bevel the insulation end 1/8” max. Thoroughly
clean the insulation.

NOTE:

The end of the jacket should be sealed to prevent water ingression into the housing. It is

recommended to use commercially available products to reconstruct the cable jacket.

STEP 3. Cable Adapter Installation

A. Apply a thin, uniform coating of the supplied lubricant to
the bore of the cable adapter and the cable insulation.
DO NOT SUBSTITUTE as other lubricants may be harmful
to products.

B. Slide cable adapter onto cable until it is ush with the

tape marker. (See Figure 6.)

STEP 4. Connector Installation

A. Use a wire brush to clean the exposed conductor and
immediately install the compression connector on the
conductor. Rotate the connector to spread the inhibitor.
Make sure the connector is fully seated. Verify check
dimension is less than 6 1/2” prior to crimping.
(See Figure 7.) Refer to crimp chart packed with connector.

C. Wipe o excess inhibitor at the base of the connector

and smooth any sharp edges on crimps of lug. Measure
check dimension after crimping to verify it is between
6-1/2” to 7-1/4”. (See Figure 8.)

STEP 5. T-Body Installation

A. Clean and lubricate the cable entrance
of the T-Body and the outside of the cable
adapter with supplied lubricant. (See Figure 9.)

B. Slide the T-Body housing onto the cable assembly,
making sure the crimp connector is properly aligned with
the T-body. The housing should bottom out onto the
connector. Verify that the cable adapter did not move

and is still ush with the tape marker. If

the adapter moves, reposition it until it

is again ush with the tape marker. (See

Figure 10.)

C. Remove tape marker.
