Overview

The NSI Industries ASC350T is a dual-rated aluminum compression splice engineered for reliable electrical connections in medium-voltage and low-voltage systems. Manufactured from high-conductivity 6061T-6 aluminum tubing, this splice ensures optimal performance for 350 MCM conductors with a temperature rating of 90 °C. The ASC350T features a center stop for precise cable installation, preventing over-insertion and ensuring consistent crimp quality. Electro-tin plating enhances corrosion resistance, making it suitable for harsh environments where moisture and oxidation are concerns. Each splice is color-coded and marked with die index information for easy tool selection and correct crimping. Pre-filled with oxide inhibitor and capped with a color-coded cap, the ASC350T maintains connection integrity over time. This splice is cULus Listed and UL486A/B Listed for wire connector applications, with a maximum voltage rating of 600V and UL Listed to 35kV when installed per cable manufacturer specifications. Recommended crimp tools include the NSI N1240 and N121D. With an outer diameter of 1.120 inches, inner diameter of 0.720 inches, and length of 3.878 inches, this splice is designed for secure, long-lasting installations in industrial, commercial, and utility applications.

How to Install Aluminum Compression Connectors

This guide provides step-by-step instructions for installing aluminum compression connectors, ensuring a secure and reliable electrical connection.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Wire brush

Supplies needed:

Aluminum compression connectors, Cable

  1. Select the appropriate connector

    Choose the correct lug or splice connector based on the size of the cable being installed, ensuring it matches the specifications in the provided chart.

  2. Strip the cable insulation

    Carefully strip the insulation from the conductor without nicking the strands, leaving enough length to fully insert the stripped conductor into the connector barrel.

  3. Clean the conductor

    Use a wire brush to clean the stripped portion of the conductor, removing any oxide films to ensure a good electrical connection.

  4. Insert the conductor into the connector

    Insert the cleaned and stripped conductor completely into the connector barrel, ensuring it fills the barrel completely.

  5. Crimp the connector

    Using the appropriate crimping tool, crimp the connector according to the manufacturer's specifications, ensuring the number of crimps is per side for a splice connector.

  6. Verify the connection

    Inspect the crimped connection to ensure it is secure and that there are no visible gaps or loose strands.
