How to Install 655/675LR and K655/K675LR Deadbreak Elbow Connectors
A comprehensive guide for the safe and correct installation of 600-ampere or 900-ampere deadbreak elbow connectors on 15kV and 25kV class systems. This guide covers cable preparation, connector assembly, and initial voltage testing.
Estimated time: 1h 30m
Tools needed:
Wire strippers, Crimping tool, Wire brush (for aluminum conductors), Hotstick, Suitable voltage sensing device, Torque wrench
Supplies needed:
655/675LR or K655/K675LR Elbow Connector, Cable Adapter, Compression Lug, Insulating Plug (if applicable), Lubricant (silicone type for test point cap), Threaded Stud (from Stud Prepack), Grounding wire (at least No. 14 AWG Copper), Suitable grounding connector, Waterproofing material (for cable jacket), HV insulated cap(s) or connector(s) (if replacing shipping covers)
- De-energize Apparatus and Inspect Parts
DANGER: Ensure all apparatus is de-energized during installation or removal of part(s). Do not touch or move energized products in the work area. Inspect parts for damage, rating and compatibility with mating parts. If this product is supplied with a protective shipping cover(s), remove this shipping cover(s) and replace with the appropriate HV insulated cap(s) or connector(s) before submerging or energizing the circuit.
- Prepare Cable for Assembly
Assemble the cable in its final assembled 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.
- Perform Cable Preparation
Follow the specific cable preparation steps (A, B, or C) that apply to your cable type. This may involve removing the outer jacket, preparing the semi-con shield, and marking specific lengths (e.g., 9-3/4 inches, 10-3/4 inches, 12-3/4 inches) as shown in the diagrams for non-jacketed, jacketed, Unishield, or lead sheath cables. Refer to separate instructions for grounding devices (20MA/21MA), jacket cable seals (600ECS), or cable shield adapters (10TL) 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, 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 Length
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 bare 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 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; 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). If dimensions are incorrect, redo the assembly.
- Install Elbow onto 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.
- 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 the mating part is not equipped with a stud. Clean and lubricate both the elbow and the mating part with lubricant supplied, keeping surfaces clean.
- Connect Elbow to Mating Part
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 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 and Cap (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 on the elbow. Push 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 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
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.
