Overview

The ABB K656LR-JAC02 is a 15/25kV, 600 Amp separable cable joint elbow designed for reliable medium-voltage power distribution connections. This complete assembly includes an elbow connector housing, insulated plug with cap, stud, shear bolt lug (AC02 range for 4/0 to 500 kcmil stranded, compressed, solid, or compact conductors), cable adapter, and lubricant. The integrated test point enables safe circuit testing without system de-energization, improving operational safety and maintenance efficiency. Key specifications include a cable insulation diameter range of 0.98 to 1.18 inches, making it compatible with a variety of medium-voltage cables. The shear bolt lug accommodates conductor sizes from 4/0 AWG to 500 kcmil, providing versatility for different cable types. The separable design allows for easy installation and disconnection using standard hand tools in a de-energized state, meeting ANSI/IEEE Standard 386 requirements. This elbow joint is engineered for underground and overhead power systems where secure, dependable terminations are critical. Its fully shielded, dead-front construction ensures safe operation in submersible applications. The robust molded rubber housing provides environmental protection while maintaining electrical integrity. The AC02 lug design supports both copper and aluminum conductors, offering flexibility in system configuration. Applications include utility substations, industrial power distribution, renewable energy systems, and commercial infrastructure where 15/25kV class equipment is required. The 600 Amp continuous current rating makes it suitable for medium-voltage feeder circuits and branch connections. The test point feature enables routine maintenance testing without disrupting service, reducing downtime and improving system reliability.

How to Install the K656LR-JAC02 Shear Bolt Connector

Instructions for installing the K656LR-JAC02 shear bolt connector onto electrical cables.

Estimated time: 30m

Tools needed:

Hexagon socket (AF 3/4” or SW19), Wire brush, Cable accessory installation instructions

Supplies needed:

Center ring, K656LR-JAC02 shear bolt connector, Cable

  1. Inspect and Prepare

    DANGER: Ensure all apparatus is de-energized before proceeding. Inspect the package contents for completeness and damage. Check all components for proper fit with the cable and mating products. Have all required tools at hand and maintain cleanliness.

  2. Insert Center Ring

    Insert the appropriate center ring into the barrel of the K656LR-JAC02 connector. Refer to the table in the installation instructions to determine the correct center ring for aluminum or copper conductors of 350/500/750 AWG-KCMIL.

  3. Prepare Cable

    Prepare the cable as specified in the instructions accompanying the applicable cable accessory. Clean the conductor using a wire brush immediately before inserting it into the barrel.

  4. Initial Bolt Tightening

    Torque bolt #1 with slow, steady turns until it makes contact with the conductor. Repeat this process for bolts #2 and #3.

  5. Shear Bolts

    Using the specified hexagon socket, and starting with bolt #1, apply torque alternately to each bolt until the head shears off. It is recommended that the connector barrel be held securely in place during this process. CAUTION: Do not use impact guns. Do not touch or move energized products in the work area.

  6. Verify Bolt Shearing

    If the bolts do not shear off flush with the connector barrel, manual rework is required. Contact Elastimold® technical services for assistance.
