CABAC BIMET SECTOR LINK 120/3/70 BLKS120/3/70 x 1/EACH

Description

Reliable Bi-Metal Sector Link for Aluminium to Copper Connections

The CABAC Bi-Metal Sector Link 120/3/70 is designed to securely connect solid or standard sector aluminium cable to circular copper cable in 3-core and 4-core installations. Built for demanding electrical environments, this bi-metal sector link uses a friction-welded aluminium sleeve and copper palm to deliver a strong, stable electrical connection between dissimilar conductors. The aluminium sleeve (99.6%) and high-conductivity copper palm (99.95%) provide excellent electrical transfer while reducing the risk of galvanic corrosion. With high conductivity and low resistivity, the link ensures efficient current flow across the joint, helping maintain system performance in switchboards, distribution networks, and heavy-duty cable terminations.

For electricians working with mixed aluminium and copper conductors, this connector provides a dependable solution that simplifies installations and supports long-term reliability.

Built for Compliance, Durability and Electrical Performance

Designed to meet international electrical standards, the CABAC sector link supports compliance across a wide range of installation environments. It aligns with AS4325 Part 1 (Australia) along with IEC, DIN/VDE, JIS, and BS standards, giving contractors confidence that installations meet recognised electrical safety and performance requirements.

The connector is manufactured with a fully annealed metal state including the joint, improving ductility and ensuring reliable crimping during installation. With a tensile strength of 110 MPa and a ductile rating of 28%, it maintains mechanical integrity even in demanding electrical infrastructure. The connector operates reliably across temperatures from -40°C to 125°C, making it suitable for both indoor switchboard environments and more exposed industrial applications where temperature stability is critical.

Trade-Ready Connectivity That Keeps Projects Moving

Electrical contractors often deal with tight project timelines, and reliable cable termination components can make a big difference on site. The CABAC Bi-Metal Sector Link provides a practical solution when transitioning between aluminium supply cables and copper distribution conductors. Its friction-welded joining method ensures a strong permanent bond between metals, helping reduce installation failures and costly rework. The design allows electricians to complete connections efficiently while maintaining electrical integrity across the joint.

Whether you’re working on switchboard upgrades, commercial fit-outs, or industrial installations, this connector helps streamline cable terminations and keeps projects moving without delays caused by incompatible conductors.
