How to Install K656/K676DLR Direct Test Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of K656/K676DLR and 656/676DLR Direct Test Elbow Connectors, including cable preparation, component assembly, and grounding procedures for 15kV and 25kV class systems.
Estimated time: 2h
Tools needed:
Wire strippers, Crimping tool, Wire brush (for aluminum conductors), High voltage insulated hot stick, Appropriate HV meters with T&B Elastimold series 200TC-1, 200TC-2, 200TC-4 or approved adapters, Vinyl plastic tape (if using flat metallic tape shield), Suitable connector for grounding wire, Torque wrench
Supplies needed:
Elbow connector (K656DLR or K676DLR), Cable Adapter, Compression Lug, Insulating Plug (if used), Lubricant (supplied with kit), Stud Prepack (supplied with kit), No. 14 AWG copper wire (or equivalent) for grounding, Tape marker, Tape retainer (if using fabric tape shield), Waterproofing material (for cable jacket, recommended)
- De-energize and Position Cable
Before starting, ensure all apparatus is de-energized. Position the cable in its final assembled location, allowing enough slack to remove elbows. If applicable, unwind concentric neutral wires. Cut the cable 1 3/4 inches (45mm) from the centerline of the mating product. DANGER: All apparatus must be de-energized during installation or removal. Failure to follow this instruction will result in serious or fatal injury.
- Prepare the Cable for Connection
Clean the outer surface of the cable for a distance of 24 inches (610mm) or up to the bent-back concentric neutral wires. Refer to specific instructions for your cable type (e.g., outer jacket, shield wires, metallic tape, fabric tape, corrugated shield, Unishield, lead sheath, or semi-con shield) to remove the outer jacket and shield to the specified dimensions. Do not cut or nick the cable insulation.
- Install Cable Adapter and Compression Lug
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, working towards the semi-con shield. Install the cable adapter, small end first, until it is flush with the edge of the tape marker. Remove protruding cable insulation, cutting it even with the end of the cable adapter, ensuring the exposed conductor is between 4 3/8 and 4 11/16 inches (111mm to 119mm). Fully insert the conductor into the compression lug (wire brush aluminum conductors immediately before insertion). Crimp the compression lug according to its supplied instructions, then wipe off any excess inhibitor. Verify the final lug-to-adapter distance is between 6 1/2 to 7 1/4 inches (165mm to 184mm).
- Install the Elbow Connector
Lubricate the cable adapter and the inside of the elbow cable entrance. Install the elbow onto the cable adapter until it cannot advance further. Ensure the cable adapter remains flush with the tape marker. Remove the tape marker.
- Connect Elbow to Mating Products
Remove protective caps from both the elbow and the mating part. If the mating part lacks a stud, hand tighten the supplied threaded stud into it. Clean and lubricate both the elbow and the mating part. Push the elbow onto the mating part, aligning the compression lug hole with the stud. For the opposite end, clean and lubricate the mating part, insert it into the elbow, engage threads, hand tighten, and then torque according to the mating part's instructions. If an insulating plug is used, clean and lubricate the voltage detection cap's inner surface, then place it on the elbow and push until it snaps into place. DO NOT CONNECT OR DISCONNECT MATING PRODUCTS WHILE ENERGIZED. DO NOT ENERGIZE WHILE DISCONNECTED.
- Ground the Cable Shield
Insert one end of a minimum No. 14 AWG copper wire 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 according to the instructions supplied with any grounding device, or via an alternate method if no device is used. It is recommended to waterproof the cable jacket at this point to prevent moisture ingress.
- Perform Direct Voltage Test (Optional)
If performing a direct voltage test, use only the appropriate direct voltage test port adapter and meter (e.g., 200TC-1, 200TC-2, 200TC-4 adapters with compatible meters). Read and understand the separate operating instructions for the specific test adapter and meter before proceeding. The cap on the direct access port should be installed at all other times. DANGER: Insertion of any object, other than the appropriate direct voltage test port adapter and meter, into the direct test port or in close proximity to it can result in electric shock which will cause serious or fatal injury.
