CABAC BIMET SECTOR LINK 240/4/120 BLKS240/4/120 x 1/EACH

Description

Reliable Bi-Metal Sector Link for Aluminium to Copper Connections

The CABAC Bimetal Sector Link 240/4/120 is designed to provide a dependable transition between solid or standard sector aluminium cable and circular copper cable in 3-core and 4-core installations. Built with a 99.6% aluminium sleeve and 99.95% copper palm, this bi-metal connector ensures excellent conductivity while preventing galvanic corrosion between dissimilar metals.

For electricians working on switchboards, distribution equipment, and heavy-duty installations, this sector link provides a clean, secure connection point that maintains current flow efficiency. The friction-welded joint between aluminium and copper delivers strong mechanical integrity, helping ensure consistent electrical performance even in demanding environments.

Built for Compliance and Long-Term Electrical Reliability

Electrical contractors need connectors they can trust to meet regulatory requirements and maintain system integrity. The CABAC bimetal sector link is manufactured to comply with recognised international standards including AS4325 Part 1 (Australia), IEC, DIN/VDE, JIS, and BS, making it suitable for professional installations requiring strict compliance.

The link is fully annealed, including the joint area, providing improved ductility and reducing the risk of cracking during installation. With an operating temperature range of -40°C to 125°C, it performs reliably in a wide range of electrical environments—from indoor switchboards to exposed industrial installations.

Strong material properties, including 110 MPa tensile strength and a 28% ductile rating, help ensure the connector maintains structural integrity over time while supporting safe current transfer.

Trade-Ready Connector for Fast, Efficient Installations

When you’re on site with tight project deadlines, using quality connectors that install easily and perform reliably can make a big difference. The CABAC bi-metal sector link is designed for quick, secure cable termination, helping electricians connect aluminium mains to copper equipment conductors without complicated workarounds.

For contractors managing residential builds, commercial switchboards, or industrial upgrades, this connector reduces downtime by providing a purpose-built solution for aluminium-to-copper transitions.

Available through iSupply Electrical’s trade-focused range, it supports efficient procurement with competitive trade pricing, fast delivery across Australia, and convenient pickup from Western Sydney trade counters—keeping your projects moving without delays.
