How to Install Elastimold 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 high voltage apparatus, including cable preparation, lug crimping, and final assembly.
Estimated time: 2h
Tools needed:
Wire strippers, Crimping tool, Wire brush, Hotstick, Suitable voltage sensing device, Torque wrench, Measuring tape or ruler, Utility knife or blade, Cleaning rags
Supplies needed:
Elbow connector (655/675LR or K655/K675LR), Cable adapter, Compression lug, Insulating plug (if used), Lubricant (silicone based), Threaded stud (if mating part not equipped), Tape marker, Grounding wire (min. No. 14 AWG Copper equivalent), Suitable ground connector, HV insulated cap(s) or connector(s), Waterproofing material (for cable jacket)
- 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 high voltage electrical equipment safety. Inspect all package contents to ensure they are complete and undamaged. Verify all components for proper fit with the cable and/or mating products. Remove any protective shipping covers and replace with appropriate HV insulated caps or connectors before submerging or energizing the circuit.
- Position and Cut Cable
Assemble the cable in its final position, ensuring enough slack 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 Cable Outer Surface
Clean the outer surface of the cable for a distance of 24 inches (610mm) or up to the bent-back concentric neutral wires.
- Prepare Cable for Installation
Follow the specific cable preparation instructions for your cable type (e.g., jacketed, non-jacketed, Unishield, lead sheath). Remove the outer jacket (if applicable) and prepare the cable insulation, semi-con shield, and metallic tape shield according to the specified dimensions (e.g., 9-3/4, 10-3/4, 12-3/4 inches from the end for various layers).
- 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 Length
Remove any 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). If not, redo the assembly.
- Crimp 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 according to the instructions supplied with the lug. Wipe off all excess inhibitor from the lug and cable adapter. Verify the distance from the end of the compression lug to the cable adapter after crimping is between 6-3/8 inches and 7-1/8 inches (162mm-181mm). If not, redo the assembly.
- Install Elbow onto Cable Adapter
Lubricate the cable adapter and the inside of the elbow's 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 and Connect to Mating Product
DANGER: Do not connect or disconnect mating products while energized. Do not energize while disconnected. Remove protective caps from both 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 Elbow onto 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 End Mating Product
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 firmly until it snaps into place. Proceed to the voltage test.
- Ground the 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 supplied with your grounding device or use an alternate method. 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 rather than pulling directly. 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.
