CABAC BIMET SECTOR LINK 185/4/70 BLKS185/4/70 x 1/EACH

Description

Efficient Aluminium-to-Copper Cable Connections

The CABAC Bi-Metal Sector Link 185/4/70 is designed to provide a reliable transition between solid or standard sector aluminium cable and circular copper cable in 3- and 4-core installations. Built with a 99.6% aluminium sleeve and 99.95% copper palm, this bi-metal link ensures consistent conductivity and strong mechanical performance in demanding electrical environments. The friction-welded joint provides a secure bond between the aluminium and copper sections, helping reduce resistance and maintain stable electrical flow across the connection.

For electricians working with mixed-metal cable systems, this design helps simplify installations while maintaining efficient current transfer and long-term performance.

Built for Reliable Performance and Compliance

When working on commercial, industrial, or large residential installations, reliable cable termination is essential. The CABAC BI-Metal Sector Link is engineered to operate across a wide temperature range of -40°C to 125°C, supporting stable performance in harsh electrical environments. Manufactured with fully annealed conductive metals, the link offers improved ductility and mechanical strength while maintaining dependable electrical properties. With aluminium conductivity of 61.8% IACS (minimum) and copper conductivity of 99.7% IACS, it supports efficient current transfer across the connection point.

The link is manufactured to meet internationally recognised standards including AS4325 Part 1, IEC, DIN/VDE, JIS, and BS, giving electricians confidence that the component is suitable for compliant installations across a wide range of electrical projects.

Trade-Ready Cable Links for Fast Installations

Designed with professional installers in mind, CABAC bi-metal links help streamline cable jointing when connecting aluminium supply cables to copper distribution systems. The sector-to-circular configuration makes them ideal for switchboard work, distribution boards, and large cable terminations commonly found in commercial and industrial environments.

For busy contractors managing tight schedules, using quality connection hardware helps reduce the risk of connection failures and costly rework. CABAC’s proven electrical components are widely trusted across the industry, making them a dependable choice for installations where reliability and compliance matter.

Available through iSupply Electrical, trades can source these links quickly alongside a broad range of electrical components, helping keep projects moving without unnecessary delays.
