Overview

The ABB 54523-TB is a tin-plated copper two-way splice connector engineered for high-reliability splicing of stranded copper conductors in industrial and utility power distribution systems. This standard barrel connector is specifically rated for a maximum operating voltage of 35kV and is designed to accommodate wire sizes up to 750 kcmil, making it suitable for heavy-duty applications where robust electrical and mechanical performance is required. The connector features a tin-plated copper construction, which provides superior corrosion resistance and ensures a low-resistance electrical connection over time, even in harsh environmental conditions. The connector is marked with a black color code and die index number 106, ensuring seamless compatibility with ABB’s installation product line and simplifying die selection for crimping tools. The internal wire stops are strategically positioned to prevent over-insertion of conductors, maintaining proper alignment and ensuring consistent crimp performance. The long barrel design maximizes crimp count, significantly enhancing wire pull-out strength and overall mechanical integrity of the splice. Additionally, the connector includes an inspection window, allowing for quick and easy visual confirmation of full conductor insertion before finalizing the crimp. The ABB 54523-TB meets stringent industry standards, including UL Listing and CSA Certification for 35kV applications, with a temperature rating of 90°C when crimped using specified tools and dies. It has been tested by Telcordia to meet NEBS Level 3 requirements, demonstrating its reliability in telecommunications and network infrastructure environments. The connector is also approved by the American Bureau of Shipping, confirming its suitability for marine and offshore applications where durability and performance under extreme conditions are critical. The SKU for this product is 54523-TB, manufactured by ABB - Installation Products under UNSPSC Code 39121449.

How to Install the 54523-TB Two Way Splicer

This guide provides step-by-step instructions for installing the 54523-TB Two Way Splicer, ensuring proper crimping and insulation for high conductivity connections.

Estimated time: 30m

Tools needed:

Wire strippers, Crimping tool, Wire brush or emery cloth

Supplies needed:

54523-TB Two Way Splicer, Heat shrink tubing, Insulation tape

  1. Prepare the cable

    Strip the insulation from the cable to a length of 1-5/8 inches, being careful not to nick the cable strands. Ensure the cable end is clean by using a wire brush or emery cloth if necessary.

  2. Insert the cable into the connector

    Insert the prepared cable into the 54523-TB connector until it stops. Ensure that the cable is fully seated within the connector.

  3. Crimp the connector

    Using the appropriate crimping tool, compress the connector between the markings, starting near the center. Refer to the installation die table to confirm the required number of compressions.

  4. Remove sharp edges

    After crimping, carefully remove any sharp edges, flash, or burrs from the connector to prevent injury or damage.

  5. Insulate the connection

    Apply heat shrink tubing over the crimped area and use a heat source to shrink it tightly around the connector. Additionally, wrap insulation tape around the connection for extra protection.
