How to Install 756LR/776LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of 756LR/776LR Deadbreak Elbow Connectors on 35kV class systems, including cable preparation, connector assembly, and grounding. Always ensure apparatus is de-energized.
Estimated time: 1h 30m
Tools needed:
Cutting tool, Wire brush, Crimping tool, Torque wrench, Hotstick, Suitable sensing device (for capacitive test points)
Supplies needed:
756LR/776LR Deadbreak Elbow Connector kit (Elbow, Cable Adapter, Compression Lug, Insulating Plug, Crimp connector, Lubricant, Stud Prepack), Cable (appropriate for 35kV class systems), Grounding device (e.g., 20MA, 21MA, 600ECS Jacket Cable Seal, or alternate method), 10TL cable shield adapter (if using UNISHIELD* or LEAD SHEATH cable), Wire (min. No. 14 AWG Copper ampacity) for grounding, Suitable connector for grounding wire, Waterproofing material (for cable jacket), Silicone lubricant
- De-energize and Inspect Apparatus
Ensure all apparatus is de-energized before starting installation or removal of parts. Inspect all parts for damage, correct rating, and compatibility with mating parts. Failure to de-energize will result in serious or fatal injury.
- Prepare Cable Position
Position the cable so it is located in its final assembled position, ensuring enough slack to provide adequate clearance for removing the elbows. Cut the cable 1-3/4 inches (45mm) from the centerline of the mating product.
- Clean Cable Jacket
Clean the outer jacket of the cable for a distance of 24 inches (610mm).
- Perform Cable Preparation
Follow the specific cable preparation instructions for your cable type. If using a 20MA, 21MA grounding device, or 600ECS Jacket Cable Seal, refer to their instructions. For UNISHIELD* or LEAD SHEATH cable, use a 10TL cable shield adapter and its instructions. For jacketed and non-jacketed cables, remove the outer jacket (if applicable) and prepare the cable according to the provided dimensions and diagrams.
- Install Cable Adapter
Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4 inch (6mm) back. Thoroughly clean and lubricate the cable insulation, always working toward the semi-con shield. Install the cable adapter, small end first, until it is flush with the edge of the tape marker.
- Prepare Conductor
Remove the protruding cable insulation by cutting it even with the end of the cable adapter. Ensure not to cut or nick the cable adapter or the conductor. The length of exposed conductor must be between 4-3/8 inches to 4-3/4 inches (111mm-121mm); otherwise, redo the assembly.
- Crimp Compression Lug
For copper conductors, fully insert the conductor into the compression lug. For aluminum conductors, wire brush the conductor and immediately fully insert it. Measure the “Check Dimension” before crimping (must be less than 7 inches/178mm). Crimp the compression lug following its supplied instructions. Wipe all excess inhibitor from the lug and cable adapter surface. The distance from the end of the lug to the cable adapter after crimping must be between 6-7/8 inches to 7-5/8 inches (175mm-194mm); otherwise, redo the assembly.
- Install Elbow
Lubricate the cable adapter and the inside of the elbow's cable entrance. Install the elbow onto the cable adapter until it cannot advance further. Make sure the cable adapter is still flush with the tape marker; if not, reposition the cable adapter. Remove the tape marker.
- Connect to Mating Product (First End)
DO NOT CONNECT OR DISCONNECT MATING PRODUCTS WHILE ENERGIZED. DO NOT ENERGIZE WHILE DISCONNECTED. Remove protective caps from both the elbow and the mating part. Hand tighten the threaded stud (supplied with the elbow) into the mating part if it is not equipped with a stud. Clean and lubricate both the elbow and the mating part with the supplied lubricant. Push the elbow onto the mating part, lining up the hole in the compression lug with the stud on the mating part.
- Connect to Mating Product (Opposite End)
Clean and lubricate the mating part for the opposite end of the elbow. Insert this mating part into the elbow. Engage the threads and hand tighten. Torque the mating part according to the instructions supplied with that mating part.
- Install Insulating Plug (If Applicable)
If an insulating plug is used as a mating part, clean and lubricate the inner surface of the voltage detection cap. Place the cap on the elbow and push down hard until the cap snaps into place. This plug provides a means for detecting system voltage.
- Ground Cable Shield
Insert one end of a wire with ampacity at least equivalent to No. 14 AWG Copper through the grounding eye and twist to make a small loop, taking care not to damage the eye. Connect this wire to ground using a suitable connector. The cable shield must be grounded according to the instructions supplied with the grounding device or through an alternate method. It is also recommended to waterproof the cable jacket at this point to prevent moisture from entering the cable.
- Perform Voltage Test (Post-Installation)
If the connector is equipped with an integral capacitance test point, remove the test point cap with a hotstick by peeling it off at an angle. WARNING: The voltage test point is a capacitance device and is not directly connected to the conductor. Do not use conventional voltage measuring equipment. Test with a suitable sensing device made for capacitive test points to determine if the cable is energized. Treat the elbow as energized until the “no voltage” indication is confirmed by other means. After testing, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
