How to Install 756/776LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of 756LR and 776LR Deadbreak Elbow Connectors on 35kV class systems, including cable preparation, lug crimping, and connection to mating apparatus.
Estimated time: 1h 30m
Tools needed:
Wire strippers, Crimp tool, Wire brush, Hotstick, Suitable sensing device for capacitive test points, Screwdriver
Supplies needed:
Elbow connector, Cable adapter, Compression lug, Insulating plug (if used), Lubricant, Stud prepack, Grounding wire (at least No. 14 AWG Copper), Suitable ground connector, HV insulated cap(s) or connector(s)
- Prepare for Installation and De-energize Apparatus
Ensure all apparatus in the work area are de-energized before beginning any installation or removal. Inspect all parts for damage, correct rating, and compatibility with mating components. Gather all required tools and supplies, and maintain cleanliness throughout the procedure.
- Position and Clean the Cable
Position the cable in its final assembled location, ensuring sufficient slack for elbow removal. Cut the cable 1-3/4 inches (45mm) from the centerline of the mating product. Thoroughly clean the outer jacket of the cable for a distance of 24 inches (610mm).
- Prepare the Cable End
Prepare the cable end by removing the outer jacket and semi-con shield according to the specific cable type (e.g., non-jacketed concentric neutral, jacketed shield wires, etc.) and the dimensions provided in the documentation. If using a grounding device or cable seal, refer to their specific instructions. For UNISHIELD* or LEAD SHEATH cable, use a 10TL cable shield adapter and follow its instructions.
- Install Cable Adapter and Expose Conductor
Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4 inch (6mm) back. Clean and lubricate the cable insulation, working towards the semi-con shield. Install the cable adapter, small end first, until it is flush with the edge of the tape marker. Carefully remove any protruding cable insulation, cutting it even with the end of the cable adapter, ensuring not to nick the adapter or conductor. The exposed conductor length must be between 4-3/8 inches (111mm) and 4-3/4 inches (121mm); re-do if outside this range.
- Crimp the Compression Lug
For copper conductors, fully insert the conductor into the compression lug. For aluminum conductors, wire brush the conductor immediately before fully inserting it into the lug. Measure the "Check Dimension" (must be less than 7 inches / 178mm) before crimping. Crimp the compression lug following the instructions supplied with the lug. After crimping, wipe off all excess inhibitor from the lug and cable adapter surface. The distance from the end of the compression lug to the cable adapter must be between 6-7/8 inches (175mm) and 7-5/8 inches (194mm); re-do if outside this range.
- Install the Elbow
Lubricate the cable adapter and the inside of the elbow's cable entrance. Install the elbow onto the cable adapter, pushing until it cannot advance further. Verify that the cable adapter remains flush with the tape marker; reposition the cable adapter if necessary. Remove the tape marker.
- Connect Elbow to Mating Apparatus
Remove any protective caps from both the elbow and the mating apparatus. If the mating apparatus is not equipped with a stud, hand tighten the threaded stud supplied with the elbow into the mating part. Clean and lubricate both the elbow and the mating part with the supplied lubricant, ensuring surfaces remain clean. Push the elbow onto the mating part, carefully aligning the hole in the compression lug with the stud on the mating part.
- Secure Opposite End and Ground the Shield
If connecting to another mating part on the opposite end of the elbow, clean and lubricate it, then insert it into the elbow. Engage the threads and hand tighten, then torque the mating part according to its specific instructions. Insert one end of a grounding wire (at least No. 14 AWG Copper ampacity) through the grounding eye and twist to form 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; follow instructions supplied with any grounding device or use an alternate method. It is also recommended to waterproof the cable jacket at this point to prevent moisture ingress.
- Perform Voltage Test (Optional but Recommended Safety Check)
If an insulating plug is used, clean and lubricate the inner surface of the voltage detection cap and place it firmly on the elbow until it snaps into place. To perform a voltage test, remove the test point cap with a hotstick, peeling it off at an angle. Use a suitable sensing device designed for capacitive test points to determine if the cable is energized, following the meter manufacturer's directions. WARNING: Do not use conventional voltage measuring equipment. Treat the elbow as energized until a "no voltage" indication is confirmed by other means, as contamination or incorrect equipment can lead to false readings. After testing, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
