CABAC BIMET SECTOR LINK 70/3/70 BLKS70/3/70 x 1/EACH

Description

Reliable Aluminium-to-Copper Connections for Sector Cables

The CABAC Bi-Metal Sector Link 70/3/70 is designed for dependable termination when linking solid or standard sector aluminium cable to circular copper cable. Built specifically for 3-core sector conductors, this connector ensures efficient conductivity between dissimilar metals without compromising electrical performance.

Using a friction-welded aluminium sleeve and copper palm, the link provides a strong and consistent electrical path while minimising resistance across the joint. For electricians working on distribution connections, switchboards, or cable transitions, this design helps maintain reliable current flow and safe operation in demanding installations.

Trade-Grade Construction with International Compliance

Manufactured with 99.6% aluminium sleeve and 99.95% copper palm, the CABAC sector link is engineered for durability and long-term reliability in electrical installations. The materials are fully annealed, including the joint, providing improved ductility and mechanical strength to handle installation stresses. Designed to perform across harsh environments, the connector operates within a wide temperature range of -40°C to 125°C, making it suitable for a variety of industrial, commercial, and infrastructure projects.

The product complies with multiple recognised international standards, including AS4325 Part 1 (Australia), IEC, DIN/VDE, JIS, and BS, ensuring confidence in performance and regulatory alignment for professional electrical work.

Built for Efficient Installation on Site

Electricians and contractors need connectors that install quickly and perform consistently across projects. The CABAC BLKS70/3/70 sector link simplifies the process of joining aluminium sector cables to copper conductors, reducing the need for improvised solutions on site.

With robust construction and reliable conductivity ratings, it helps maintain system integrity in distribution networks, switchboard connections, and cable transitions. Whether you’re completing commercial installations, industrial maintenance, or infrastructure upgrades, this connector delivers dependable performance while helping keep jobs moving on schedule.
