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 600-ampere and 900-ampere deadbreak elbow connectors on 15kV and 25kV class systems, including cable preparation, lug crimping, and final connection.
Estimated time: 1h 30m
Tools needed:
Cable cutting tool, Measuring tape or ruler, Cable strippers or knife, Crimping tool (specific to lug), Wire brush (for aluminum conductors), Torque wrench, Hotstick, Suitable sensing device (for capacitive test points)
Supplies needed:
Deadbreak Elbow Connector, Cable Adapter, Compression Lug, Insulating Plug (if applicable), Lubricant (silicone based), Threaded Stud (from Stud Prepack, if needed), Cable, Cleaning agent, Cleaning cloth, Grounding wire (No. 14 AWG Copper or equivalent), Suitable ground connector, Waterproofing material (for cable jacket), Protective caps (to be removed)
- Prepare for Installation and Cable Assembly
DANGER: All apparatus must be de-energized during installation or removal of parts. Do not touch or move energized products in the work area. This product should be installed only by competent personnel trained in good safety practices involving high voltage electrical equipment. Inspect package contents for completeness and damage. Inspect all components for proper fit with the cable and/or mating products. Gather all required tools and supplies. Assemble the cable in its final position with enough slack to provide adequate clearance for removing the elbows. 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. Remove the outer jacket (where applicable) and prepare the cable according to the specified dimensions for insulation and semi-con shield.
- Install the Cable Adapter
Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4 inch (6mm) back. Thoroughly clean, 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 inches and 4-9/16 inches (108mm-116mm); otherwise, redo the assembly. 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; this dimension 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); otherwise, redo the assembly.
- Install the Elbow onto the Cable Adapter
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 Mating Products
WARNING: 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. 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 the mating part. CAUTION: When constructing 600-amp L-Kits, be sure to tighten each component to specified torque per instructions provided.
- 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 and place it on the elbow. Push down hard until the cap snaps into place.
- Ground the Cable Shield and Waterproof
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 the 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 Voltage Test
Remove the test point cap with a hotstick, peeling it off at an angle rather than pulling directly in line with the test point assembly. WARNING: The voltage test point is a capacitance device; it is not directly connected to the conductor. Do not use conventional voltage measuring equipment. Follow the manufacturer’s directions for the meter that is 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, etc., around the test point or use of the wrong measuring equipment can provide a false 'no voltage' indication on an energized elbow. 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 has been made, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
