Overview

The ABB K656SR-M0360 is a 600 Amp, 15/25kV deadbreak straight receptacle designed for fully shielded, submersible cable connections on high-voltage apparatus bushings. This 600 Series component enables straight cable termination on switchgear or electrical apparatus equipped with 600 Amp bushings, supporting conductor sizes from #2 AWG to 1250 kcmil for both aluminum and copper cables. The molded rubber housing is fully shielded and submersible, constructed with 100% peroxide-cured EPDM materials for long-term reliability in demanding environments. Key specifications include a continuous current rating of 600 Amps and momentary withstand of 25kA symmetrical for 10 cycles. For the 15kV class, the receptacle meets 8.3kV phase-to-ground and 14.4kV phase-to-phase operating voltages, with a 95kV BIL impulse withstand and 34kV AC one-minute withstand. The 25kV class supports 16.2kV phase-to-ground and 28kV phase-to-phase voltages, with a 140kV BIL impulse withstand and 45kV AC one-minute withstand. Corona extinction sensitivity is 3pC at 11kV AC for 15kV class and 21.5kV AC for 25kV class. The K656SR-M0360 accommodates cable insulation diameters from 1.370 inches to 1.630 inches, with an aluminum compression lug rated for compressed stranded conductors up to 650 kcmil, compacted solid conductors up to 750 kcmil, or compacted mm² conductors up to 400 mm². The integrated cable adapter, lug, and retaining ring ensure secure assembly and reliable electrical termination. A non-corrosive capacitive test point allows for safe voltage verification without de-energizing the system. Optional accessories enable visible external separation, bypass, isolation, dead-ending, grounding, and testing, as well as adding taps for expanded functionality. This receptacle is ideal for applications requiring high-capacity power transmission in industrial, utility, and commercial switchgear environments where submersible, fully shielded connections are critical. The deadbreak design allows for safe connection and disconnection in a de-energized state, minimizing downtime during maintenance or reconfiguration.

How to Install K656SR and M656SR Straight Receptacles

This guide provides detailed instructions for the safe and proper installation of K656SR and M656SR straight receptacles, enabling an in-line cable connection to a standard ANSI-386 600 amp 15kV, 25kV, or 35kV bushing. Follow all safety warnings.

Estimated time: 2h

Tools needed:

5/8-11 tap, Hex wrench, Torque wrench with 15/16 socket, Wire strippers, Hotstick, Suitable sensing device for capacitive test points, 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

  1. Review Safety and Prepare

    DANGER: Ensure all apparatus is de-energized before installation or removal. Do not touch or move energized products. Read all instructions, inspect parts for damage and compatibility, and gather all required tools and supplies. Maintain cleanliness throughout the procedure.

  2. Prepare Apparatus Bushing

    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.

  3. Assemble Bushing Converter

    Apply 3-4 drops of Loctite to the threads of the brass bolt. Assemble the bushing converter onto the apparatus bushing. Assemble the contact adapter to the apparatus bushing, with the bolt hole facing out, using the 5/8-inch brass bolt. Torque to 60 ft-lbs.

  4. Prepare Cable End

    Train the cable end and straighten it into its final position. Cut the cable end squarely to ensure maximum available length for crimp growth.

  5. Manage Concentric Neutral Wires

    If applicable, unwrap the concentric neutral wires a distance of 30 inches (76 cm). DO NOT CUT these wires. Bend and fold them back out of the way.

  6. Clean Outer Jacket

    Wipe the outer jacket of the cable clean for a distance of 38 inches (96.5 cm) or up to the concentric neutral wires.

  7. Slide Receptacle Housing

    Slide the receptacle housing onto the cable for a distance of 30 inches (76 cm).

  8. Prepare Cable Insulation

    Remove the semi-con shield and install a tape marker to the dimensions shown in the documentation (10-1/4 to 11-1/4 inches). Do not cut or nick the cable insulation during this process.

  9. Bevel and Lubricate Cable Insulation

    Bevel the end of the cable insulation at a 45-degree angle, approximately 1/4 inch (6 mm) back. Thoroughly clean, then lubricate the cable insulation, always working toward the semi-con shield.

  10. Install Cable Adapter

    Install the cable adapter, small end first, onto the cable insulation until it is flush with the edge of the tape marker.

  11. Expose Conductor

    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 exposed conductor should be 4-3/4 to 5 inches (12.06cm-12.7cm). If the length is incorrect, redo the assembly from Step 8.

  12. Position and Secure Holding Collar

    Position the holding collar over the conductor and flush against the cable adapter. Using the supplied hex wrench, tighten the setscrew securely.

  13. Prepare and Insert Conductor into Crimp Connector

    Remove the protective cap from the crimp connector. If using aluminum cable wire, brush the conductor. Immediately insert the conductor fully into the crimp connector, which contains inhibitor.

  14. Verify Crimp Connector Length

    Measure the distance from the end of the crimp connector to the holding collar. If this distance is over 7 inches (17.8 cm), do not proceed. Redo all previous work from Step 13.

  15. Confirm Component Orientation

    Confirm that the receptacle housing, cable adapter, crimp connector, and contact adapter are oriented in the correct order. Crucially, confirm that the bolt hole in the crimp connector is aligned with the bolt hole in the contact adapter.

  16. Crimp Connectors

    Crimp the connectors following the instructions packaged with the connectors. Rotate each crimp 90 degrees to ensure a secure connection.

  17. Verify Crimped Connector Length

    After crimping, measure the distance from the end of the connector to the holding collar. If the distance is over 7 inches (17.8 cm), do not proceed. Redo all previous work from Step 13.

  18. 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 bolt.

  19. Torque Bolt

    Using a torque wrench with a 15/16 socket, tighten the bolt to 50-60 ft-lbs. IMPORTANT: Do not attempt to move or reposition any part of the assembly after the bolts are tightened.

  20. Lubricate Adapters

    Generously apply the supplied lubricant or an ELASTIMOLD approved lubricant to the outside of the cable adapter and the area of the bushing adapter as shown in the documentation. DO NOT SUBSTITUTE other lubricants, as they may be harmful to the product.

  21. Seat Receptacle Housing

    Slide the receptacle housing over the cable adapter and up to the edge of the interface. Insert the nylon venting rod (supplied). Slide the receptacle housing onto the bushing converter until it is fully seated. Remove the venting rod.

  22. Connect Grounding and Neutral Wires

    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.

  23. Install 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.

  24. Perform Voltage Test (Capacitance Test Point)

    If the connector has an integral capacitance test point, remove the test point cap with a hotstick, peeling off at an angle. WARNING: This is a capacitance device, not directly connected to the conductor. Use a suitable sensing device made for capacitive test points. Treat the elbow as energized until a 'no voltage' indication is confirmed by other means. Clean and lubricate the inside surface of the cap with silicone lubricant and replace it.
