How to Install Elastimold 655/675LR and K655/K675LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe and proper installation of Elastimold 655/675LR and K655/K675LR deadbreak elbow connectors on 15kV and 25kV class systems. It covers cable preparation, connector assembly, and grounding procedures.
Estimated time: 2h
Tools needed:
Cable cutter, Measuring tape, Cable strippers, Utility knife, Wire brush (for aluminum conductors), Crimping tool, Torque wrench, Hotstick, Capacitive voltage sensing device
Supplies needed:
Elastimold deadbreak elbow connector (655/675LR or K655/K675LR), Cable adapter, Compression lug, Insulating plug (if used), Lubricant, Threaded stud (if mating part not equipped), Cleaning solution, Lint-free cloth, Grounding wire (No. 14 AWG Copper or equivalent), Suitable grounding connector, Waterproofing material (optional), Voltage detection cap (if insulating plug used), Tape marker
- Ensure Safety and Inspect Components
DANGER: All apparatus must be de-energized during installation or removal of parts. Do not touch or move energized products. Inspect all package contents and components for completeness, damage, proper rating, and compatibility with mating parts. Remove any protective shipping covers and replace with appropriate HV insulated caps or connectors before energizing.
- Prepare Cable for Assembly
Assemble the cable in its final position, ensuring 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 the outer surface of the cable for a distance of 24 inches (610mm) or up to the bent back concentric neutral wires.
- Perform Cable Preparation
Remove the outer jacket (if applicable) and prepare the cable according to the specific type (e.g., non-jacketed concentric neutral, jacketed shield wires, flat metallic tape shield, fabric tape shield, or longitudinally corrugated shield) as shown in the product diagrams. Refer to separate instructions for 20MA/21MA grounding devices, 600ECS Jacket Cable Seals, or 10TL cable shield adapters if used.
- 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
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. Verify that the length of the exposed conductor is between 4-1/4 inches and 4-9/16 inches (108mm-116mm); otherwise, redo the assembly.
- Install 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 instructions supplied with the lug. Wipe all excess inhibitor from the lug and cable adapter. Verify the distance from the end of the lug to the cable adapter after crimping is between 6-3/8 inches to 7-1/8 inches (162mm-181mm); otherwise, 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 it cannot advance further. Ensure the cable adapter remains flush with the tape marker; reposition if necessary. Remove the tape marker.
- Prepare Mating Products
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. Hand tighten the threaded stud (supplied with the elbow) into the mating part if it is not already equipped with a stud. Clean and lubricate both the elbow and the mating part with the supplied lubricant, ensuring surfaces remain clean.
- Connect Elbow to Mating Part
Push the elbow onto the mating part, carefully lining up 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. CAUTION: When constructing 600amp L-Kits, ensure each component is tightened to its specified torque.
- 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 it snaps into place. Proceed to the voltage test directions.
- Ground Cable Shield
Insert one end of a grounding wire (with ampacity 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 for any grounding device used, or ground via an alternate method if no device is present. It is also recommended to waterproof the cable jacket at this point to prevent moisture ingress.
- Perform Voltage Test
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 to determine if the cable is energized. 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.
