How to Install Elastimold Deadbreak Elbow Connectors (655/675LR & K655/K675LR)
This guide provides step-by-step instructions for the safe and proper installation of Elastimold 655/675LR and K655/K675LR Deadbreak Elbow Connectors, designed for fully shielded, submersible high voltage cable connections. It covers cable preparation, connector assembly, and grounding procedures.
Estimated time: 1h 30m
Tools needed:
Wire strippers, Crimping tool, Wire brush (for aluminum conductors), Hotstick, Suitable sensing device (for capacitive test points), Torque wrench
Supplies needed:
Elastimold Deadbreak Elbow Connector (655/675LR or K655/K675LR), Cable Adapter, Compression Lug, Insulating Plug (if applicable), Lubricant (silicone), Threaded Stud (if mating part not equipped), Grounding wire (No. 14 AWG Copper or equivalent), Suitable ground connector, Waterproofing material (for cable jacket), 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. This product should be installed only by competent personnel trained in good safety practices involving high voltage electrical equipment. Inspect all package contents and components for damage, correct rating, and compatibility with mating parts. Ensure all required tools and supplies are at hand and maintain cleanliness throughout the procedure.
- Prepare the Cable
Assemble the cable in its final position with enough slack to allow for elbow removal. For concentric neutral cable, unwind the neutral wires. Cut the cable 1-3/4” (45mm) from the center line of the mating product. Clean the outer surface of the cable a distance of 24” (610mm) or up to the bent back concentric neutral wires. Remove the outer jacket (where applicable) and prepare the cable insulation and semi-con shield according to the specific cable type and diagrams provided in the full instructions.
- Install the Cable Adapter
Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4” (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 and Crimp Compression Lug
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 should be between 4-1/4” and 4-9/16” (108mm-116mm). For aluminum conductors, wire brush the conductor immediately before insertion. Fully insert the conductor into the compression lug. Measure the “Check Dimension” before crimping; it should be less than 6-3/8”. 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” to 7-1/8” (162mm-181mm).
- Install the Elbow Connector onto the Cable
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. Make sure the cable adapter is still flush with the tape marker. If not, reposition the cable adapter. Remove the tape marker.
- Connect to Mating Apparatus
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 the mating part is not equipped with a stud. Clean and lubricate both the elbow and the mating part with the lubricant supplied. Push the elbow onto the mating part, lining up the hole in the compression lug with the stud on the mating part.
- Connect Opposite Mating Part (if applicable)
Clean and lubricate the mating part for the opposite end of the elbow. Insert the mating part into the elbow. Engage the threads and hand tighten. Torque the mating part according to the instructions supplied with that 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 piece of wire with ampacity at least equivalent to No. 14 AWG Copper through the grounding eye and twist to make a small loop. Do not damage the eye. Connect this wire to ground using a suitable connector. The shield of the cable must be grounded. Ground according to the instructions supplied with the grounding device. If no grounding device is used, the shield must be grounded through an alternate method. It is also recommended that the jacket of the cable be waterproofed at this point to prevent moisture from entering the cable.
- Perform Final Torque Check and Voltage Test
CAUTION: When constructing 600amp L-Kits, be sure to tighten each component to specified torque per instructions provided. To perform a voltage test, remove the test point cap with a hotstick by 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. Test with 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” test point indication is confirmed by other means to prevent serious or fatal injury. After voltage detection, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
