This guide provides step-by-step instructions for the safe and proper installation of 600-ampere and 900-ampere deadbreak elbow connectors on high voltage cable systems. Ensure all apparatus are de-energized before beginning any work.
Estimated time: 2h
Tools needed:
Wire strippers, Crimping tool, Wire brush, Hotstick, Suitable sensing device for capacitive test points, Suitable grounding connector, Torque wrench
Supplies needed:
655/675LR or K655/K675LR Elbow Connector kit (includes Elbow, Cable Adapter, Compression Lug, Insulating Plug, Lubricant, Stud Prepack), No. 14 AWG Copper wire (or equivalent), Silicone lubricant, Waterproofing material (for cable jacket)
- De-energize and Inspect Apparatus
DANGER: All apparatus must be de-energized during installation or removal of parts. Do not touch or move energized products. Inspect all parts for damage, correct rating, and compatibility with mating parts before starting installation.
- Assemble and Clean 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 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.
- Prepare Cable for Connection
Remove the outer jacket (if applicable) and prepare the cable according to the specific type (e.g., non-jacketed concentric, jacketed shield, flat metallic tape, fabric tape, or longitudinally corrugated shield) as detailed in the product documentation, ensuring correct measurements for cable insulation, semi-con shield, and tape marker.
- Bevel Insulation and 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
Remove the protruding cable insulation by cutting it even with the end of the cable adapter. Exercise caution to avoid cutting or nicking 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); otherwise, 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 must be less than 6-3/8 inches. Crimp the compression lug according to the instructions supplied with the lug. Wipe all excess inhibitor from the lug and cable adapter surface. After crimping, the distance from the end of the lug to the cable adapter must be between 6-3/8 inches and 7-1/8 inches (162mm-181mm); otherwise, 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; if not, reposition it. Remove the tape marker.
- Prepare Mating Product
Remove any protective caps from both the elbow and the mating part. If the mating part lacks a stud, hand tighten the threaded stud supplied with the elbow into the mating part. Clean and lubricate both the elbow and the mating part with the supplied lubricant, ensuring all surfaces remain clean.
- Connect Elbow to Mating Part
Push the elbow onto the mating part, carefully aligning the hole in the compression lug with the stud on the mating part.
- Connect Opposite Mating Part (if applicable)
If connecting to an opposite mating part, clean and lubricate its surface. Insert the mating part into the elbow, engage the threads, and hand tighten. Torque the mating part according to the specific instructions provided with that component.
- Install Insulating Plug (if used)
If an insulating plug is used as a mating part, clean and lubricate the inner surface of the voltage detection cap. Place the cap onto the elbow and push down firmly until it snaps securely into place.
- Ground the Cable Shield
Insert one end of a No. 14 AWG Copper wire (or equivalent ampacity) through the grounding eye and twist it 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 either via a grounding device (following its instructions) or an alternate method. Waterproof the cable jacket at this point to prevent moisture ingress.
- Torque Components for 600A L-Kits
CAUTION: When constructing 600-amp L-Kits, ensure that each component is tightened to its specified torque according to the instructions provided with the L-Kit.
- Perform Voltage Test
WARNING: The voltage test point is a capacitance device, not directly connected to the conductor. Do not use conventional voltage measuring equipment. Remove the test point cap with a hotstick, peeling it off at an angle. Use a suitable sensing device, designed for capacitive test points, to determine if the cable is energized. Treat the elbow as energized until a 'no voltage' indication is confirmed by other means. After testing, clean and lubricate the inside surface of the cap with silicone lubricant and replace it on the test point.
