Overview

NSI Industries GL250NB is a 2-hole short barrel copper compression lug specifically engineered for 250MCM flexible copper cables. This lug is designed with a gentle, continuous flared end, which significantly simplifies the insertion of flexible and extra-flexible cables. This feature is particularly beneficial for demanding applications such as locomotive, welding, and mining cable installations, where cable flexibility is paramount. Beyond ease of insertion, the flared end plays a crucial role in reducing pressure on the cable strands after the compression process is complete. This reduction in pressure helps to protect the cable strands from chafing and potential breakage, especially in scenarios involving cable movement. For enhanced durability and protection against environmental factors, the GL250NB is tin-plated, providing superior corrosion resistance. This compression lug is rated for 600 volts and is exclusively designed for use with copper cables. It features a single mounting hole for secure and straightforward attachment. The GL250NB is an ideal solution for heavy-duty industrial environments where the integrity and longevity of cable connections are of utmost importance.

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.
