Overview

The ABB K656I-K0270 is a 15-25kV 600 Series Deadbreak Separable Straight Joint Package designed for reliable medium-voltage cable connections in power distribution systems. This 2-way joint accommodates cable insulation diameters from 1.090 inch to 1.310 inch, making it suitable for compressed stranded 4/0 AWG, compacted solid 250 kcmil, or 125 mm² compact conductors. The integrated test point enables safe voltage verification without system de-energization, reducing downtime during maintenance or testing. The aluminum compression lug ensures secure, low-resistance connections that maintain system integrity under load. This deadbreak design prevents accidental energization of the cable end, enhancing worker safety during installation or servicing. Commonly used in utility substations, industrial power feeds, and renewable energy interconnections, this joint package provides a durable, field-proven solution for medium-voltage cable splicing. The 600 Series design aligns with industry standards for separable connectors, offering compatibility with existing ABB and third-party equipment. Installation requires standard compression tools and follows ABB’s documented procedures for optimal performance.

How to Install K656 Deadbreak Receptacles

This guide provides step-by-step instructions for the safe and proper installation of one leg of K656CY, K656CH, or K656I Deadbreak Receptacles, designed for splicing and tapping solid dielectric cables rated for 600A at 15kV and 25kV.

Estimated time: 1h 30m

Tools needed:

Hex wrench, Torque wrench with 15/16 inch socket, Wire brush (for aluminum cable), Assembly tool (650ATY or 600RRT), Rag, Approved safety solvent

Supplies needed:

Receptacle housings, Cable adapters, Center section (I, Wye, or H), Aluminum holding collars, Lubricant (supplied or ELASTIMOLD approved), Hex-head bolts, Crimp connectors, Belleville washers, Flat washers, Nylon venting rod, No. 14 AWG copper wire (for grounding), Tape (for markers and support)

  1. Prepare for Installation and Inspect Components

    DANGER: Ensure all apparatus is de-energized before starting. Inspect all receptacle components for damage, correct rating, and compatibility with mating parts. Confirm all package contents are complete and undamaged, and check threads for proper fit.

  2. Clean Cable Jacket and Position Housing

    Wipe the outer cable jacket clean for a distance of 38 inches (96.5 cm) from the end. Cut the cable end squarely. If using an ECS grounding device, slide its tube onto the cable 38 inches. Then, slide the receptacle housing onto the cable 30 inches (76.2 cm).

  3. Prepare Cable End (Type-Specific)

    Refer to the special cable preparation supplement (Part A for Jacketed Concentric Neutral or Part B for Flat Metallic Tape Shielded) for specific instructions. This involves removing the outer jacket and semi-con shield to specified lengths, creating a tape marker, beveling the insulation, and thoroughly cleaning the insulation. Lubricate the cable and the inside of the cable adapter, then slide the adapter onto the cable until flush with the tape marker.

  4. Trim Insulation and Assemble Retaining Ring

    Remove any protruding cable insulation, cutting it even with the end of the cable adapter. Ensure the exposed conductor measures 4 3/4 to 5 inches (12.1-12.7 cm). Assemble the aluminum retaining ring over the conductor, snug it firmly against the cable adapter, and hand-tighten the socket head screw. Confirm the exposed conductor now measures 4 3/8 to 4 3/4 inches (11.1-12.1 cm).

  5. Install and Crimp Connector

    Remove the protective cap from the crimp connector. If using aluminum cable, wire brush the conductor immediately before fully inserting it into the crimp connector. Confirm bolt holes align with the mating part. Crimp the connector following the provided instructions, rotating each crimp 90 or 180 degrees. Verify the distance from the end of the connector to the holding collar is 6 3/4 to 7 inches (17.1-17.8 cm).

  6. Assemble and Torque Splice Bolts

    Assemble the washers and bolt: flat washer against the spade contact, then the Belleville washer (concave side down), followed by the hex-head bolt. Hand tighten. Using a torque wrench with a 15/16 inch socket, tighten all bolts to 50 to 60 ft. lbs. Do not move or reposition any part after tightening.

  7. Lubricate and Position Receptacle Housing

    Apply the supplied or ELASTIMOLD approved lubricant generously to the outside of the cable adapter, the splice section, and the inside mating surface of the receptacle housing. Slide the receptacle housing over the cable adapter and up to the edge of the interface. Insert the nylon venting rod.

  8. Engage Receptacle Housing with Assembly Tool

    Attach either the 650ATY or 600RRT assembly tool. Use the tool to slowly slide the receptacle housing completely over the splice section. Once fully engaged, remove the nylon venting rod. WARNING: Do not place hands on the threaded rod or guide shaft if using the 600RRT tool.

  9. Complete Grounding

    If an ECS grounding device is used, complete its installation according to its specific instructions. Connect a short length of No. 14 AWG copper wire (or equivalent) to the grounding eyes of the housings. Make a small loop and twist tightly, taking care not to damage the eye, and connect to ground.
