Overview

The ABB Type ASP4 Aluminum Splice (SKU: ASP4) is a compact, high-conductivity connector designed for medium-voltage applications up to 35kV. Rated for 4 AWG stranded aluminum conductors, this splice measures 1-7/8 inches in length and features a tin-plated finish for corrosion resistance and improved electrical contact. The green die-cast body provides clear voltage class identification and mechanical durability. Engineered for utility and industrial power distribution systems, the ASP4 splice ensures reliable connections in overhead and underground installations where aluminum conductors are standard. Its compact design allows for efficient use in confined spaces while maintaining full-rated current capacity. The tin plating enhances long-term performance by reducing oxidation at connection points, a critical factor in high-voltage environments. Compatible with standard compression tooling, the ASP4 splice simplifies installation in field conditions. The 4 AWG rating aligns with common distribution feeder applications, making it a practical choice for utility crews and contractors working on medium-voltage systems. ABB’s Installation Products line delivers consistent performance across industrial applications where electrical integrity and mechanical reliability are non-negotiable.

How to Install ABB ASP AL9CU Aluminum Compression Splices

This guide provides step-by-step instructions for installing ABB ASP AL9CU aluminum compression splices, suitable for stranded, compressed, and compact aluminum and copper cables.

Estimated time: 15m

Tools needed:

Wire brush, Appropriate crimping tool and die set (e.g., hydraulic or mechanical)

Supplies needed:

ASP AL9CU Aluminum Compression Splice, Aluminum or Copper Cable, Soap and water (for cleaning skin)

  1. Disconnect Power and Verify Cable Compatibility

    WARNING: Risk of shock, disconnect power before installation. Verify the wire size marked on the aluminum splice matches the actual cable size to be used. Ensure the product is installed by a qualified electrician in accordance with national and local electrical codes.

  2. Prepare the Cable Insulation

    Strip the cable insulation to the appropriate length, taking extreme care not to nick or damage the cable strands during the process.

  3. Clean the Cable Conductor

    Wire brush the cable side that will be inserted into the connector to ensure proper electrical contact. Do not remove the oxide inhibitor from the splice barrel itself, as insufficient compound can result in an unsafe connection.

  4. Insert Cable into Splice

    Fully insert the prepared cable into the compression splice barrel until it reaches the stop or is fully seated.

  5. Crimp the Splice

    Refer to the 'Tool and Die Index' in the product documentation to select the correct tool/die combination for your specific cable size. Crimp the connector the specified number of times shown on the chart. For splices, make the first crimp just outside the knurl on each side of the center and space subsequent crimps uniformly along the splice.

  6. Clean Excess Inhibitor

    Wipe off any excess oxide inhibitor from the exterior of the crimped splice. If prolonged skin contact occurs with the compound, wash immediately with soap and water. Consult a physician if swallowed or contact with eyes.
