CABAC BIMET SECTOR LINK 120/4/25 BLKS120/4/25 x 1/EACH

Description

Reliable Aluminium-to-Copper Cable Connections

The CABAC Bi-Metal Sector Link 120/4/25 is designed to safely and efficiently connect solid or standard sector aluminium cable to circular copper cable in 3- and 4-core installations. Built with a high-conductivity aluminium sleeve and copper palm, it creates a dependable transition between dissimilar conductors without compromising electrical performance.

The aluminium sleeve delivers excellent conductivity while the copper palm provides a secure termination point, ensuring a strong and stable electrical connection. This makes it a practical solution for electricians working with mixed conductor types commonly found in distribution, switchboard, and industrial cable installations.

With fully annealed conductive materials and a robust construction, these links support consistent current flow while helping reduce connection resistance across aluminium-to-copper terminations.

Built for Compliance and Long-Term Reliability

When you’re installing infrastructure that needs to last, material quality and compliance matter. The CABAC bi-metal sector link is manufactured using friction welding to IEC standards, producing a strong, permanent bond between the aluminium and copper components.

Constructed from 99.6% aluminium and 99.95% copper, the link provides excellent electrical performance and durability even in demanding environments. Its fully annealed metal state, including the joint, enhances ductility and reliability during installation.  The connector is designed to operate across a wide temperature range from -40°C to 125°C, making it suitable for installations exposed to varying site conditions.

Manufactured in line with internationally recognised standards, including AS4325 Part 1 (Australia) as well as IEC, DIN/VDE, JIS, and BS standards, these links provide electricians with confidence that the installation meets required compliance expectations.

A Practical Solution for Busy Trade Installations

Electrical contractors and maintenance teams need connectors that install easily and perform reliably once energised. The CABAC bi-metal sector link provides a straightforward solution for linking aluminium supply cables to copper terminations, helping simplify installations in switchboards, distribution panels, and industrial cable runs.

For contractors working across residential developments, commercial builds, or maintenance upgrades, having dependable cable links reduces the risk of connection issues and costly rework later on. Available through iSupply Electrical with fast dispatch and convenient trade ordering, these links help keep projects moving—whether you’re managing a tight build schedule, responding to maintenance work, or sourcing compliant components for larger electrical projects.
