How to Install 655/675LR and K655/K675LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of 655/675LR and K655/K675LR Deadbreak Elbow Connectors, including cable preparation, lug crimping, and connection to high voltage apparatus. This product should only be installed by competent personnel trained in high voltage electrical equipment safety practices.
Estimated time: 1h 30m
Tools needed:
Wire strippers, Crimping tool, Wire brush, Torque wrench, Hotstick, Suitable sensing device (for capacitive test points), Utility knife or beveling tool
Supplies needed:
655/675LR or K655/K675LR Elbow Connector kit (includes Elbow, Cable Adapter, Compression Lug, Insulating Plug, Lubricant, Stud Prepack, Crimp chart), No. 14 AWG Copper wire (or equivalent ampacity), Suitable grounding connector, HV insulated cap(s) or connector(s), Silicone lubricant, Waterproofing material (for cable jacket)
- Prepare for Installation and De-energize Apparatus
DANGER: All apparatus must be de-energized during installation or removal of parts. Do not touch or move energized products. Inspect all parts for damage, rating, and compatibility with mating parts. Remove any protective shipping covers and replace with appropriate HV insulated caps or connectors before submerging or energizing the circuit. Gather all required tools and supplies, and maintain cleanliness throughout the procedure.
- Position and Clean Cable
Assemble the cable in its final position, ensuring enough slack to allow for elbow removal. For concentric neutral cable, unwind the concentric neutral wires. Cut the cable 1-3/4 inches (45mm) from the centerline of the mating product. Clean the outer surface of the cable a distance of 24 inches (610mm) or up to the bent back concentric neutral wires.
- Prepare Cable Insulation and Shield
Remove the outer jacket (where applicable) and prepare the cable insulation, semi-con shield, and shield wires according to the cable type (e.g., non-jacketed, jacketed, unishield, lead sheath, flat metallic tape, fabric tape, or longitudinally corrugated shield). Refer to specific installation instructions supplied with any 20MA/21MA grounding device, 600ECS Jacket Cable Seal, or 10TL cable shield adapter if these products are being used for cable preparation, shield connection, and grounding.
- 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, 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 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 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 and immediately fully insert it into the compression lug. Measure the 'Check Dimension' before crimping; it should be less than 6-3/8 inches. Crimp the compression lug following the crimping instructions supplied with the lug. Wipe all excess inhibitor from the 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 6-3/8 inches to 7-1/8 inches (162mm-181mm). If dimensions are incorrect, redo the assembly.
- Install Elbow Connector
Lubricate the cable adapter and the inside of the elbow cable entrance. Install the elbow onto the cable adapter until the elbow cannot advance further. Ensure the cable adapter is still flush with the tape marker. If not, reposition the cable adapter. Remove the tape marker.
- Connect Elbow to First Mating Part
DANGER: DO NOT CONNECT OR DISCONNECT MATING PRODUCTS WHILE ENERGIZED. DO NOT ENERGIZE WHILE DISCONNECTED. Remove 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. Push the elbow onto the mating part, lining up the hole in the compression lug with the stud on the mating part.
- Connect Elbow to Second Mating Part (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. CAUTION: When constructing 600-amp L-Kits, ensure each component is tightened to the specified torque per instructions.
- Install Insulating Plug and Voltage Detection Cap (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 it snaps into place. Proceed to the voltage test directions.
- Ground the Cable Shield and Waterproof Jacket
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, taking care not to damage the eye. Connect this wire to ground using a suitable connector. The shield of the cable must be grounded; ground it according to the instructions supplied with the grounding device, or through an alternate method if no grounding device is used. It is also recommended that the jacket of the cable be waterproofed at this point to prevent moisture from entering the cable.
- Perform Voltage Test
The ELASTIMOLD deadbreak elbow connector is equipped with an integral capacitance test point. Remove the test point cap with a hotstick, peeling it off at an angle rather than pulling directly. WARNING: The voltage test point is a capacitance device and is not directly connected to the conductor. Do not use conventional voltage measuring equipment. Follow the manufacturer’s directions for the meter used. Test with a suitable sensing device, made for use with separable connectors manufactured with capacitive test points, to determine if the cable is energized. Contamination, moisture, dirt, or using the wrong measuring equipment can provide a false 'no voltage' indication. To prevent serious or fatal injury, treat the elbow as energized until the 'no voltage' test point indication is confirmed by other means. After voltage detection, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
