How to Install K656SR and M656SR Straight Receptacles
This guide provides step-by-step instructions for installing K656SR and M656SR Straight Receptacles, which offer an in-line cable connection to standard ANSI-386 600 amp 15kV, 25kV, or 35kV bushings.
Estimated time: 1h 30m
Tools needed:
5/8-11 tap, Hex wrench, Torque wrench (with 15/16 socket), Wire strippers, Brush (for aluminum cable wire), Suitable crimping tool
Supplies needed:
Receptacle housing, Bushing adapter, Cable adapter, Aluminum holding collar, Hex head bolt, Hose clamp (35kV only), Crimp connector, Belleville washer, Flat washer, Nylon venting rod, Lubricant (supplied or ELASTIMOLD approved), Brass bolt, Bushing converter contact, Loctite, Tape marker, No. 14 AWG copper wire (or equivalent), Suitable connector (for neutral and grounding wires)
- Prepare the Apparatus Bushing
DANGER: Ensure all apparatus is de-energized before beginning installation. If a stud is present in the apparatus bushing, remove it and re-tap the hole using a 5/8-11 tap. Clean and lubricate the apparatus bushing and bushing converter interface. Assemble the bushing converter onto the apparatus bushing. Apply 3-4 drops of Loctite to the threads of the brass bolt. Assemble the contact adapter to the apparatus bushing, with the bolt hole facing out, using the 5/8” brass bolt. Torque to 60 ft.-lbs.
- Prepare the Cable End
Train the cable end and straighten it into its final position. Cut the cable squarely to ensure maximum available length for crimp growth. If applicable, unwrap the concentric neutral wires a distance of 30” (76cm), do not cut them, and bend/fold them back out of the way. Wipe the outer jacket clean for a distance of 38” (96.5cm) or up to the concentric neutral wires.
- Slide Receptacle Housing and Prepare Cable Insulation
Slide the receptacle housing onto the cable a distance of 30” (76cm). Remove the semi-con shield and install a tape marker to the dimensions of 10-1/4” (26.04cm) and 11-1/4” (28.58cm) as shown in the documentation. Do not cut or nick the cable insulation. Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4” (6mm) back. Thoroughly clean and then lubricate the cable insulation, always working toward the semi-con shield.
- Install Cable Adapter and Prepare Conductor
Install the cable adapter, small end first, until it is flush with the edge of the tape marker. 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. Verify that the length of the exposed conductor is 4 3/4” – 5” (12.06cm–12.7cm); if not, redo the assembly.
- Position Holding Collar and Crimp Connector
Position the holding collar over the conductor and flush against the cable adapter. Using the supplied hex wrench, tighten the setscrew. Remove the protective cap from the crimp connector. If using aluminum cable wire, brush the conductor and immediately insert it into the crimp connector, ensuring it is fully inserted into the crimp barrel. Measure the distance from the end of the connector to the holding collar; if it is over 7” (17.8cm), do not proceed and redo all previous work.
- Confirm Orientation and Crimp Connectors
Confirm that components are oriented in the order: Receptacle Housing, Cable Adapter, Crimp Connector, Contact Adapter. Confirm that the bolt hole in the crimp connectors is aligned with the bolt hole in the contact adapter. Crimp the connectors following the instructions packaged with them, rotating each crimp 90 degrees. After crimping, measure the distance from the end of the connector to the holding collar; if it is over 7” (17.8cm), do not proceed and redo all previous work.
- Assemble Washers and Bolt
Assemble the washers and bolt in the following order: Flat washer against the spade contact, Belleville washer (concave side down), then the hex-head bolt. Hand tighten the assembly. Using a torque wrench with a 15/16 socket, tighten to 50-60 ft.-lbs. Do not attempt to move or reposition any part of the assembly after the bolts are tightened.
- Lubricate and Seat Receptacle Housing
Apply the supplied lubricant or ELASTIMOLD approved lubricant generously to the outside of the cable adapter and the area of the bushing adapter. DO NOT SUBSTITUTE other lubricants, as they may be harmful. Slide the receptacle housing over the cable adapter and up to the edge of the interface. Insert the supplied nylon venting rod. Slide the receptacle housing onto the bushing converter until fully seated. Remove the venting rod.
- Ground the Receptacle Housing
Connect a short piece of No. 14 AWG copper wire (or equivalent) to the grounding eye of the receptacle housing. Make a small loop and twist tightly, taking care not to damage the eye. Gather together the concentric neutral wires. Using a suitable connector, connect the neutral wires and the grounding wire.
- Secure Hose Clamp (35kV Only)
FOR 35kV ONLY: Position the hose clamp between the locator bumps on the receptacle housing. Tighten the clamp until an audible click is heard.
