CABAC BIMET SECTOR LINK 240/4/240 BLKS240/4/240 x 1/EACH

Description

Reliable Aluminium-to-Copper Connections for High-Load Cables

The CABAC Bi-Metal Sector Link 240/4/240 is designed to provide a dependable connection between solid or standard sector aluminium cable and circular copper cable, making it a practical solution for electrical contractors working with mixed-metal installations. Built with an aluminium sleeve and copper palm, the link ensures efficient current transfer while reducing the risk of galvanic corrosion between dissimilar conductors. The friction-welded joint creates a strong and stable transition point, helping maintain conductivity across the connection while supporting high-load electrical systems.

For electricians working on switchboards, distribution upgrades, or industrial power circuits, this sector link provides a simple way to transition between aluminium supply cables and copper terminations without compromising performance.

Built for Compliance, Durability, and Electrical Safety

When working on regulated installations, compliance and reliability are essential. The CABAC bi-metal sector link is manufactured to meet internationally recognised standards, helping contractors maintain installation quality and meet site requirements.

The link features fully annealed metal construction, providing flexibility and mechanical strength for reliable crimping and long-term durability. With an operating temperature range from -40°C to 125°C, it is suitable for demanding environments often found in commercial and industrial electrical systems. Electrical conductivity is maintained through high-purity metals, including 99.6% aluminium and 99.95% copper, ensuring efficient power transfer and dependable performance in distribution applications.

Compliance with AS4325 Part 1 (Australia) and multiple international standards helps ensure the product meets recognised electrical and manufacturing benchmarks.

Trade-Ready Solution for Fast, Efficient Installations

Electrical contractors need components that install quickly and perform reliably once energised. The CABAC BLKS240/4/240 bi-metal link helps reduce installation time by providing a ready-to-use solution for connecting aluminium sector cables to copper terminations.

This makes it particularly useful for switchboard installations, distribution upgrades, and infrastructure projects where aluminium supply cables are common but copper terminations are required.

Available through iSupply Electrical, contractors benefit from competitive trade pricing, reliable stock availability, and convenient ordering. Whether ordering online for delivery across Australia or picking up from Western Sydney trade counters, electricians can source the parts they need without delays that impact project timelines.
