Overview

The ABB RRK 2 HS Aluminum Heat-Shrink Compression Splice Kit (SKU: RRK 2 HS) is a precision-engineered solution for joining 2 AWG aluminum conductors in electrical installations. This kit includes a 3-inch compression connector and a 5.5-inch heat-shrink insulator, providing a secure, insulated splice for aluminum wiring. The red color-coded design ensures easy identification in the field, while the included five 5/8-inch dies enable consistent crimping for reliable performance. Designed for industrial, commercial, and utility applications, the RRK 2 HS kit delivers environmental protection against moisture, corrosion, and mechanical stress. The heat-shrink insulator forms a watertight seal, extending the lifespan of the splice in harsh conditions. The compression connector ensures a low-resistance electrical connection, critical for maintaining system efficiency and safety in high-demand environments. Compatible with standard crimping tools, the RRK 2 HS simplifies installation while meeting ANSI C119.1 requirements for aluminum conductor splicing. The compact design and included dies make it suitable for confined spaces and high-volume installations. Trust ABB’s Installation Products for a field-proven solution in electrical infrastructure.

How to Install a Heat-Shrink Compression Splice Kit

This guide provides step-by-step instructions for installing a heat-shrink compression splice kit. Disconnect power before installation and ensure all safety precautions are followed.

Estimated time: 30m

Tools needed:

Wire strippers, Wire brush, Crimping tool, Torch, Safety glasses, Protective gloves

Supplies needed:

Heat-shrink tubing, Connector, Oxide inhibitor (for aluminum conductors)

  1. Strip Cable Insulation

    Strip both ends of the cable insulation 1/2 the length of the connector, plus 1/4 inch, as shown in Figure 1.

  2. Clean Cable Insulation

    Clean the stripped cable insulation.

  3. Place Heat-Shrink Tubing

    Place the heat-shrink tubing over the clean cable end. Protect the heat-shrink tubing from possible damage from the conductor as it is placed over the cable end, as shown in Figure 2.

  4. Prepare Conductor

    Wire brush the conductor strands. If using aluminum conductors, coat the conductor with oxide inhibitor and wire brush it into the strands.

  5. Install and Crimp Connector

    Install the connector and crimp it using the recommended die marked on the connector. After crimping, clean and deburr the connector if required, as shown in Figure 3.

  6. Shrink Heat-Shrink Tubing

    Center the heat-shrink tubing over the splice and hold it in place. Apply the outer 3 to 4 inch tip of the flame to the heat-shrinkable material with a rapid brushing motion. Keep the flame moving to avoid scorching. Begin shrinking at the center of the tube, working the flame around all sides to apply uniform heat (a). After the center portion shrinks, work the torch towards one end (b), then to the opposite end (c) until completely shrunk, as shown in Figure 4.

  7. Inspect Splice

    Inspect the complete splice. The properly installed tube will be smooth and conform to the connection, with adhesive visible at both ends. Reheat any flat spots or wrinkles. Allow the installation to cool before touching, moving, or placing in service.
