How to Install K655/K675LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of K655/K675LR Deadbreak Elbow Connectors, including cable preparation, lug crimping, and connection to mating apparatus.
Estimated time: 1h 30m
Tools needed:
Wire strippers, Knife or utility blade, Measuring tape or ruler, Wire brush (for aluminum conductors), Crimping tool, Torque wrench, Hotstick, Suitable voltage sensing device, Suitable grounding connector
Supplies needed:
K655/K675LR Deadbreak Elbow Connector kit (includes Elbow, Cable Adapter, Compression Lug, Insulating Plug, Lubricant, Stud Prepack), Cable (concentric neutral, unishield, lead sheath, jacketed, non-jacketed, flat metallic tape shield, fabric tape shield, longitudinally corrugated shield), Grounding wire (at least No. 14 AWG Copper), Waterproofing material (for cable jacket), HV insulated cap(s) or connector(s) (if replacing shipping covers), Cleaning solution, Tape marker
- De-energize and Prepare Cable
DANGER: All apparatus must be de-energized during installation or removal. Do not touch or move energized products. Assemble the cable in its final position with enough slack for elbow removal. For concentric neutral cable, unwind the neutral wires. Cut the cable 1-3/4 inches (45mm) from the centerline of the mating product.
- Clean and Prepare Cable Outer Surface
Clean the outer surface of the cable for a distance of 24 inches (610mm) or up to the bent-back concentric neutral wires. Follow the specific cable preparation instructions (A, B, or C) that apply to your cable type. For jacketed and non-jacketed cables, remove the outer jacket (if applicable) and prepare the cable insulation, semi-con shield, and shield wires to the specified dimensions (e.g., 9-3/4", 10-3/4", 12-3/4" from the cut end, using a tape marker).
- Prepare Cable Insulation and Install Cable Adapter
Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4 inch (6mm) back. Thoroughly clean and then 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.
- Prepare Conductor and Verify Length
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 the exposed bare conductor must be between 4-1/4 inches and 4-9/16 inches (108mm-116mm). If the length is outside this range, redo the assembly.
- Crimp 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 compression lug. Measure the 'Check Dimension' before crimping; it should be less than 6-3/8 inches. Crimp the compression lug according to the instructions supplied with the lug. After crimping, wipe all excess inhibitor from the compression lug and cable adapter surface. The distance from the end of the compression lug to the cable adapter should be between 6-3/8 inches to 7-1/8 inches (162mm-181mm). If dimensions are incorrect, redo the assembly.
- Install Elbow onto Cable Adapter
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. Ensure the cable adapter remains flush with the tape marker. If not, reposition the cable adapter. Remove the tape marker.
- Connect Elbow to Mating Product
WARNING: DO NOT CONNECT OR DISCONNECT MATING PRODUCTS WHILE ENERGIZED. DO NOT ENERGIZE WHILE DISCONNECTED. Remove any protective caps from the elbow and the mating part. If the mating part 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, aligning the hole in the compression lug with the stud on the mating part.
- Connect Opposite Mating Product (if applicable)
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 specific mating part. If an insulating plug is used as a mating part, clean and lubricate the inner surface of the voltage detection cap and place it on the elbow, pushing down hard until the cap snaps into place.
- Ground the Cable Shield
Insert one end of a grounding wire (at least equivalent to No. 14 AWG Copper) 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 a grounding device, or use an alternate method if no device is used. It is also recommended to waterproof the cable jacket at this point to prevent moisture ingress.
- Perform Voltage Test
To determine if the circuit is energized, use the integral capacitance test point. Remove the test point cap with a hotstick, peeling it off at an angle. WARNING: The voltage test point is a capacitance device, not directly connected to the conductor. Do not use conventional voltage measuring equipment. Use a suitable sensing device designed for capacitive test points. Contamination or incorrect equipment can give a false 'no voltage' indication. Treat the elbow as energized until the 'no voltage' indication is confirmed by other means to prevent serious injury. After testing, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
