Overview

ABB ULCK 2 HS is a copper heat-shrink in-line compression splice kit engineered for 2 AWG copper conductors. This kit combines a compression splice with heat-shrink tubing to deliver a mechanically robust and electrically continuous connection. The splice ensures a gas-tight, vibration-resistant joint that resists pull-out forces, while the heat-shrink tubing provides environmental protection against moisture, corrosion, and mechanical stress. Installation is straightforward: prepare the conductors, crimp the splice, and slide the pre-lubricated heat-shrink tubing over the connection. The tubing centers automatically and seals the splice without the need for taping, heat guns, or pull cords. This splice kit is ideal for in-line connections in power distribution systems, control panels, and wiring systems where copper conductors are specified. It is suitable for both indoor and outdoor use when installed according to ABB’s guidelines and applicable electrical codes. The kit is part of ABB’s Installation Products line, designed for durable, long-lasting splices in industrial, commercial, and utility applications.

How to Install a Heat-Shrink Compression Splice Kit

This guide provides step-by-step instructions for installing a heat-shrink compression splice kit, covering cable preparation, connector crimping, and proper heat-shrink application for a secure splice.

Estimated time: 30m

Tools needed:

Torches, Wire brush, Crimping tool

Supplies needed:

Heat-shrink tubing, Compression connector, Oxide inhibitor

  1. Prepare Cable Insulation

    WARNING: Risk of shock, disconnect power before installation. Strip both ends of the cable insulation to a length equal to half the connector's length plus an additional 1/4 inch. CAUTION: Wear safety glasses and protective gloves.

  2. Clean Cable Insulation

    Thoroughly clean the prepared cable insulation on both ends to ensure proper adhesion and splice integrity.

  3. Position Heat-Shrink Tubing

    Carefully place the heat-shrink tubing over one of the clean cable ends. Ensure the tubing is protected from potential damage by the conductor strands as it slides over the cable end.

  4. Prepare Conductor Strands

    Wire brush the conductor strands to remove any oxidation. If working with aluminum conductors, coat the conductor with an oxide inhibitor and wire brush it thoroughly into the strands.

  5. Install and Crimp Connector

    Install the compression connector onto the prepared cable ends, ensuring proper seating. Crimp the connector using the recommended die size marked on the connector itself. After crimping, clean and deburr the connector if necessary.

  6. Shrink Heat-Shrink Tubing

    Center the heat-shrink tubing over the splice and hold it firmly in position. Using a torch, apply the outer 3-4 inch tip of the flame to the heat-shrinkable material with a rapid, brushing motion. Continuously move the flame to prevent scorching. Begin shrinking at the center of the tube, applying uniform heat around all sides. Once the center is shrunk, work the torch towards one end, then to the opposite end, until the entire tube is completely shrunk.

  7. Inspect and Cool Splice

    Inspect the completed splice. A properly installed tube will be smooth, conform tightly to the connection, and adhesive will be visible at both ends. Reheat any flat spots or wrinkles as needed. Allow the installation to cool completely before touching, moving, or placing it into service.
