CABAC BIMET SECTOR LINK 185/4/50 BLKS185/4/50 x 1/EACH

Description

Reliable Aluminium-to-Copper Connections for Sector Cables

The CABAC Bi-Metal Sector Link 185/4/50 is designed to securely connect solid or standard sector aluminium cable to circular copper cable, providing a reliable transition between different conductor materials. Built for 3 and 4 core cable installations, these bi-metal links help electricians create stable electrical joints where aluminium distribution cables need to terminate onto copper conductors. The aluminium sleeve and copper palm construction ensures proper conductivity across dissimilar metals while minimising resistance at the joint. With a friction-welded connection between aluminium and copper, the link provides a strong and consistent bond that performs reliably in demanding installations such as switchboards, mains connections, and distribution systems.

For electricians working on commercial or industrial jobs where aluminium feeders are common, these links provide a dependable solution that simplifies cable termination and ensures consistent electrical performance.

Built to Meet International Electrical Standards

CABAC sector links are manufactured using high-purity aluminium and copper conductors to maintain strong conductivity and mechanical performance. The aluminium sleeve and copper palm are fully annealed, delivering the ductility and tensile strength needed for dependable crimping and long-term durability.

Designed for professional electrical installations, these links comply with multiple international standards including AS4325 Part 1, along with recognised standards from IEC, DIN/VDE, JIS, and BS. This level of compliance helps contractors confidently install the component across residential, commercial, and industrial applications while meeting strict electrical safety requirements.

With an operating temperature range from –40°C to 125°C, the connector performs reliably across harsh environmental conditions often encountered in electrical infrastructure, plant environments, and outdoor installations.

Trade-Ready Components for Efficient Installations

On busy job sites, electricians need termination hardware that installs quickly and performs consistently. The CABAC BLKS185/4/50 bi-metal sector link is engineered for straightforward crimping and dependable connections, helping reduce installation time when terminating aluminium sector cables. By ensuring compatibility between aluminium feeders and copper conductors, these links eliminate the need for complex workarounds and help maintain reliable system performance across switchboards and distribution equipment.

Available through iSupply Electrical’s trade-focused range, contractors can source these connectors quickly alongside switchboards, meter boxes, and other distribution hardware—keeping projects moving without unnecessary delays.
