How to Install Elastimold 655/675LR and K655/K675LR Deadbreak Elbow Connectors
This guide provides comprehensive instructions for the safe installation, wiring, and connection of Elastimold 655/675LR and K655/K675LR Deadbreak Elbow Connectors to high voltage apparatus. Ensure all safety precautions are followed.
Estimated time: 1h
Tools needed:
Wire brush, Crimping tool, Hotstick, Suitable sensing device for capacitive test points, Torque wrench (for mating parts), Wire strippers
Supplies needed:
Elbow connector, Cable adapter, Compression lug, Insulating plug (if applicable), Lubricant (silicone), Threaded stud, No. 14 AWG Copper wire (or equivalent) for grounding, Suitable grounding connector, Tape marker, Protective caps (for elbow and mating part), HV insulated cap(s) or connector(s) (if replacing shipping covers)
- Prepare for Installation and Safety Check
DANGER: All apparatus must be de-energized during installation or removal. Do not touch or move energized products. Inspect all package contents to ensure they are complete and undamaged. Verify all components for proper fit with the cable and/or mating products. Have all required tools at hand and maintain cleanliness throughout the procedure. This product should only be installed by competent personnel trained in high voltage electrical equipment safety practices.
- Prepare the Cable
Assemble the cable in its final position with 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 for a distance of 24 inches (610mm) or up to the bent back concentric neutral wires. Remove the outer jacket (if applicable) and prepare the cable according to the specific cable type (e.g., Unishield, Jacketed, Non-Jacketed, Flat Metallic Tape Shield, Fabric Tape Shield, or Longitudinally Corrugated Shield) as detailed in the product documentation, ensuring correct dimensions for insulation and semi-con shield removal.
- Install the 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 the Conductor
Remove the protruding cable insulation by cutting it even with the end of the cable adapter. Be careful not to 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 the Compression Lug
For copper conductors, fully insert the conductor into the compression lug. For aluminum conductors, wire brush the conductor immediately before fully inserting 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 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 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; 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 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. Push the elbow onto the mating part, aligning the hole in the compression lug with the stud on the mating part.
- Complete the Connection and Torque
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 specific instructions supplied with that mating part. CAUTION: When constructing 600-amp L-Kits, ensure each component is tightened to the 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. Place the cap on the elbow and push down hard until it 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, 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 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 to waterproof the cable jacket 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 specific 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 incorrect 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.
