Overview

The NSI Industries GL50058B is a single-hole, short barrel copper compression lug meticulously engineered for flexible copper cables. This specific lug is designed to accommodate cables up to 500 MCM in size. Its construction features a gentle, continuous flared end, a critical design element that ensures the ease of cable insertion, particularly for highly flexible and extra flexible copper conductors. This flared end is specifically beneficial for demanding applications such as locomotive cable, welding cable, and mining cable, where the flexibility of the conductor is paramount. Beyond simplifying installation, the flared end plays a crucial role in reducing pressure on the cable strands once the lug is installed. This reduction in pressure helps to protect the delicate strands from chafing and potential breakage, which can occur as a direct result of cable movement during operation. To further enhance its durability and longevity, the GL50058B is tin-plated. This tin plating provides essential corrosion resistance, safeguarding the lug from degradation in various environmental conditions and ensuring a reliable connection over time. The lug is rated for use with 600 volts, making it suitable for a wide range of electrical applications. It is important to note that this compression lug is exclusively designed and rated for use with copper cables only. The GL50058B features a single mounting hole, which facilitates straightforward and secure installation onto equipment or termination points. This design makes it an ideal component for industrial applications where robust, high-performance cable connections are essential for maintaining operational integrity and safety.

How to Install Copper Compression Connectors

This guide provides step-by-step instructions for installing copper compression connectors, ensuring secure and reliable electrical connections.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Wire brush

Supplies needed:

Copper compression connectors, Cable

  1. Strip the conductor

    Carefully strip the insulation from the conductor without nicking the strands, ensuring the stripped length allows for complete insertion into the connector barrel.

  2. 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.

  3. Insert the conductor

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

  4. Crimp the connector

    Using the appropriate crimping tool, apply pressure to crimp the connector securely onto the conductor, following the manufacturer's suggested crimp locations.

  5. Verify the connection

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