Overview

The ABB K151LS-C1270 is a 15/25kV, 200 amp dead break locking splice designed for medium-voltage cable installations requiring permanent, fully shielded connections. This splice accommodates cable insulation diameters from 0.805 to 1.060 inches and features an aluminum compression lug for secure conductor termination. The dead break design allows for complete isolation of energized components before disconnection, enhancing safety in utility and industrial power distribution systems. The locking mechanism provides a robust connection that resists accidental disengagement, with a pull-out strength of up to 500 lbs. The fully submersible molded rubber housing is 100% peroxide cured, using EPDM insulation and conductive materials for long-term reliability. The K151LS-C1270 meets ANSI/IEEE Standard 386 and is rated for 15kV and 25kV voltage classes with impulse withstand ratings of 95kV and 125kV respectively. It supports continuous operation at 200 amps and handles momentary currents up to 10kA symmetrical for 10 cycles. This splice is ideal for new installations or repairs in vaults, direct burial, or other demanding environments where permanent, fully shielded connections are required. The product includes installation instructions, lubricant, and crimp charts for proper assembly.

How to Install the K151LSP Non-Separable Straight Plug

This guide provides detailed instructions for the installation and connection of the K151LSP Non-Separable Straight Plug, designed to permanently connect solid dielectric type cables by mating with an ELASTIMOLD K151LSR receptacle. Ensure all safety precautions are followed.

Estimated time: 1h

Tools needed:

Cable cutting tool, Wire strippers, Wire brush, Crimping tool, Rag

Supplies needed:

K151LSP package contents (Conductor Contact, Nylon Venting Rod, Lubricant), Approved solvent, Silicone grease, #14AWG copper wire (customer supplied, if not using ELASTIMOLD grounding device), Cable (jacketed concentric neutral or copper tape shield)

  1. Prepare the Cable End

    DANGER: Ensure all apparatus is de-energized before beginning installation. For jacketed concentric neutral cable, cut and remove the cable jacket 8 inches from the cable end, allowing sufficient concentric neutral wires for grounding. For copper tape shield cable, cut and remove the cable jacket 7-1/2 inches from the cable end, then remove the copper tape shield 6-1/2 inches from the end of the cable. If using an ECS or MA grounding device, follow its specific installation instructions for outer jacket cut back.

  2. Remove Insulation and Conductive Shield

    Remove 1-1/8 inches of cable insulation and conductive shield. For #1 stranded/compressed and #1/0 compressed/solid or larger aluminum cable, remove 1-7/8 inches. Cut squarely, do not pencil. Wire brush bare aluminum conductors and immediately insert them into the crimp barrel.

  3. Crimp the Socket Terminal

    Crimp the socket terminal onto the bared conductor, ensuring the conductor remains fully seated in the connector. Refer to the crimp chart provided with the contact. Start the crimps at the crimp line imprinted on the crimp barrel and rotate each successive crimp or indent at least 90 degrees. If using aluminum cable, carefully wipe any excess inhibitor from the contact and cable insulation.

  4. Prepare the Semi-Conductive Shield and Insulation

    Temporarily remove the plastic pin. Remove the semi-conductive shield to a point 7-3/4 inches to 7-13/16 inches back from the end of the socket with a straight, smooth, 'squared' cut. DO NOT CUT OR NICK THE INSULATION. Pencil the insulation 1/8 inch. Replace the plastic pin. Clean the outer jacket and thoroughly clean the insulation to remove all traces of semi-conducting residue by wiping with a rag wet with an approved solvent, always wiping from the end of the cable toward the outer jacket. If using an ECS or MA grounding device, install it following its appropriate instructions.

  5. Lubricate the Cable and Plug Housing

    Keep the cable insulation and plug clean. Apply the supplied lubricant sparingly to the cable as shown in the documentation and to the inside of the housing. DO NOT SUBSTITUTE other lubricants, as they may be harmful to this product or its mating product.

  6. Install the Plug onto the Cable

    Push the cable into the housing until the leading edge of the socket contact is flush with the front edge of the plug. Remove the plastic pin from the socket and discard it.

  7. Connect to the Mating Receptacle

    Lubricate the nose of the plug with silicone grease. Place the nylon rod into the receptacle face until it bottoms (approximately 1-3/4 inches), taking care to ensure the nylon rod is not cut while mating parts, which could leave material inside the interface. Insert the plug assembly into the receptacle as far as possible until you feel the contact assembly 'CLICK' and lock into its final position.

  8. Verify Connection and Remove Nylon Rod

    Verify the locking contact by pulling on the cables; DO NOT PULL THE HOUSING. If the parts separate, repeat steps 7B and 7C. Once verified, pull out the nylon rod.

  9. Connect Grounding (if applicable)

    If an ELASTIMOLD grounding device is not being used, connect a length of #14AWG or equivalent copper wire (customer supplied) through the grounding tab and twist tightly. Then, connect the grounding assembly of the connector to the system ground by merging it with the cable shield of each cable. Seal the grounding wires and connections to prevent corrosion.
