CABAC BIMET SECTOR LINK 120/4/70 BLKS120/4/70 x 1/EACH

Description

Built for Reliable Aluminium-to-Copper Connections

The CABAC Bimetal Sector Link 120/4/70 BLKS120/4/70 is designed to securely connect solid or standard sector aluminium cable to circular copper cable, providing a dependable transition between dissimilar conductors. This bi-metal link uses a friction-welded aluminium sleeve and copper palm, creating a strong electrical connection that helps maintain consistent conductivity across the joint.

For electricians working on distribution upgrades, switchboard installations, or cable terminations, this link helps ensure a smooth transition between aluminium and copper conductors without compromising performance. The fully annealed construction improves ductility and strength, helping reduce the risk of cracking during crimping and installation while delivering reliable electrical flow in demanding environments. With its robust design and carefully matched materials, the link supports efficient cable termination while helping maintain the integrity of the electrical system.

Engineered to Meet Global Electrical Standards

Compliance and reliability are critical when installing connections in electrical infrastructure. The CABAC bi-metal sector link is manufactured to meet recognised international standards including AS4325 Part 1 (Australia), IEC, DIN/VDE, JIS, and BS, providing confidence when specifying components for commercial, industrial, or infrastructure projects.

The friction welding process used to join the aluminium sleeve to the copper palm creates a strong metallurgical bond that improves mechanical strength and electrical continuity. With high conductivity copper and aluminium materials, the link supports efficient current flow while maintaining durability under operating conditions. The link is designed to perform in a wide range of environments with an operating temperature range from -40°C to 125°C, making it suitable for installations exposed to varying site conditions. For contractors working on projects where compliance and reliability are non-negotiable, using certified components helps ensure installations meet industry expectations.

Trade-Ready Components for Faster Installations

On busy job sites, having the right connector available can save valuable installation time. The CABAC BLKS120/4/70 sector link simplifies the process of joining aluminium and copper conductors, helping electricians complete cable terminations efficiently without sourcing additional transition hardware.

Its design supports straightforward installation in switchboards, distribution systems, and cable jointing applications where mixed conductor materials are present. Reliable connectors also reduce the likelihood of rework, helping contractors maintain project timelines and avoid costly delays.

Available through trade-focused electrical wholesalers with large product ranges and reliable supply, this type of component helps electricians source the parts they need quickly—keeping projects moving and installations compliant.
