Overview

The NSI Industries SC-250 is a high-conductivity tinned copper compression splice designed for reliable electrical connections. Engineered from premium copper tubing, this standard barrel splice offers superior conductivity and durability. Its tin plating provides excellent corrosion resistance, ensuring long-term performance in demanding industrial environments. The SC-250 is specifically designed for 250 MCM copper cable, with an expanded wire range of 1/0 AWG when used with the NSI N12ID dieless compression tool. This splice features a positive center stop to prevent over-insertion of conductors and flared openings at both ends, facilitating easy cable insertion, especially for flexible and extra-flexible cables such as locomotive, welding, and mining cables. Each splice is clearly marked with the appropriate die index and color-coded (Yellow for SC-250) for quick and accurate identification, streamlining installation and inventory management. The SC-250 is UL486A Listed and cULus Listed (155027), with a temperature rating of 90°C and a maximum voltage rating of 600V. Crucially, it is listed for 35KV maximum when properly installed according to the cable manufacturer's voltage stress relief instructions. The barrel has an I.D. of 0.594 inches and an O.D. of 0.752 inches, with a total length of 2.000 inches. It is suitable for copper cables only and is rated for Class H and Class M conductors. This splice is a critical component for ensuring secure and efficient power transmission in various industrial applications, offering a dependable connection for medium to heavy-duty electrical systems. Standard packaging includes 25 pieces per carton.

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.
