Deadbreak Elbow Connectors
CONTENTS: Elbow, Cable Adapter, Compression Lug, Insulating Plug, Crimp connector, Lubricant, Stud Prepack,
Installation Instructions, Crimp chart.
The 756/776LR connectors are designed to: 1) provide fully shielded, fully submersible deadfront cable connections to high
voltage apparatus and 2) provide a means to splice and tap 600--ampere (756LR) or 900--ampere (776LR) systems. The
connectors are rated for use on 35kV class systems.
DANGER
All apparatus must be de--energized during installation
or removal of part(s). For loadbreak products follow
operating instructions. All deadbreak connectors must
be de--energized before operating. All 200A deadbreak
connectors must be mechanically secured with bails
when connected.
All apparatus must be installed and operated in
accordance with individual user, local, and national
work rules. These instructions do not attempt to
provide for every possible contingency.
Do not touch or move energized products.
Excess distortion of the assembled product may result
in its failure.
Inspect parts for damage, rating and compatibility with
mating parts.
This product should be installed only by competent
personnel trained in good safety practices involving
high voltage electrical equipment. These instructions
are not intended as a substitute for adequate training or
experience in such safety practices.
Failure to follow these instructions will result in
damage to the product and serious or fatal injury.
If this product is supplied with a protective shipping
cover(s), remove this shipping cover(s) and replace
with the appropriate HV insulated cap(s) or
connector(s) before submerging or energizing the
circuit.

STEP 4 CABLE ADAPTER
Bevel the end of the cable insulation at a 45_angle, approximately 1/4” (6mm) back. Thoroughly clean, then lubricate cable
insulation always working toward semi--con shield. Install cable adapter, small end first, until it is flush with the edge of the tape
marker.

STEP 5 CONDUCTOR
Remove the protruding cable insulation by cutting it even
with the end of the cable adapter. Do not cut or nick the cable
adapter or the conductor. The length of exposed conductor
should be between 4--5/8”to5”(117mm--127mm).
Otherwise redo assembly.

STEP 6 COMPRESSION LUG
Copper Conductor: Fully insert conductor into compression Lug.
Aluminum Conductor:Wire brush conductor and immediately fully insert conductor into compression lug.
Measure the “Check Dimension” before crimping. This
dimension should be less than 6--7/8” (175mm) otherwise
redo assembly. Crimp the compression lug following the
crimping instructions supplied with the lug. Wipe all excess
inhibitor from compression lug and cable adapter surface
after crimping. The distance from the end of the
compression lug to the cable adapter after crimping should
be between 6--7/8” to 7--5/8” (175mm--194mm). Otherwise
redo assembly.

DO NOT ENERGIZE WHILE DISCONNECTED.
Remove protective caps from the elbow and the mating part. Hand tighten the threaded stud supplied with the elbow into
mating part, if the mating part is not equipped with a stud. Clean and lubricate both the elbow and the mating part with lubricant
supplied. (Keep surfaces of elbow and mating part clean.)

STEP 11
If an insulating plug is used as a mating part, clean and
lubricate inner surface of the voltage detection cap and
place on elbow. Push down hard until cap snaps into place.
CAUTION: The insulating plug provides a means for
detecting system voltage. Follow VOLTAGE TEST
directions below.

STEP 12
Insert one end of a piece of wire with ampacity at least
equivalent to No. 14 AWG Copper through the grounding
eye and twist to make a small loop. Do Not damage the eye.
Connect wire to ground using a suitable connector.
The shield of the cable must be grounded. Ground
according to the instructions supplied with the grounding
device. If no grounding device is used, the shield must be
grounded through an alternate method.
It is also recommended that the jacket of the cable be
waterproofed at this point to prevent moisture from entering
the cable.

CAUTION: When constructing 600amp L--Kits be sure to tighten each component to specified torque per instructions
provided with plug connectors.
VOLTAGE TEST
ELASTIMOLD connectors equipped with an integral capacitance test point can be used to establish whether or not the
circuit is energized. When using the test point, complete the following steps:
1. Remove test point cap with a hotstick. When removing cap, PEEL OFF AT AN ANGLE rather than pulling directly in line
with the test point assembly.
2. WARNING: THE VOLTAGE TEST POINT IS A CAPACITANCE DEVICE, IT IS NOT DIRECTLY CONNECTED TO THE
CONDUCTOR. Do not use conventional voltage measuring equipment. Follow the manufacturer’s directions for the
meter that is used. Test with a suitable sensing device, made for use with separable connectors manufactured with
capacitive test points, to determine if cable is energized. Contamination, moisture, dirt, etc. around the test point or use
of the wrong measuring equipment can provide a false “no voltage” indication on an energized elbow. To prevent
serious or fatal injury treat the elbow as energized until the “no voltage” test point indication is confirmed by other means.
3. After voltage detection has been made, clean and lubricate the inside surface of the cap with silicone grease and
replace it on the test point.
