CABAC BI-MET 4 CORE SECT LINK AL240 TO CU120MM BLKSC240/4/120 x 1/EACH

Description

Efficient Aluminium-to-Copper Connection for URD Installations

The CABAC BI-MET 4 Core Sector Link AL240 to CU120mm is designed to deliver a reliable transition between sector-shaped aluminium conductors and stranded copper conductors. Built specifically for four-core solid sector aluminium cables commonly used in URD installations, this bi-metal link allows electricians to confidently join aluminium feeders to copper terminations without compromising electrical performance.

The aluminium end features a sector-shaped internal profile with a circular external barrel, allowing the use of standard hex crimp dies instead of specialised nest and indent tooling. This design simplifies installation on site, reducing setup time and making the termination process faster for electricians working on residential developments, commercial projects, or infrastructure works.

With a 240mm² aluminium sector conductor capacity and 120mm² copper connection, it provides a clean and efficient solution for aluminium-to-copper transitions in multi-core cable systems.

Built for Long-Term Performance and Electrical Compliance

Manufactured from 99.6% pure aluminium sleeve and 99.95% pure copper palm, the CABAC bi-metal link ensures excellent conductivity and long-term durability in demanding electrical environments. The components are friction welded to IEC standards, creating a strong metallurgical bond that maintains reliable electrical performance across the joint.

The connector is fully annealed, delivering the ductility required for secure crimping while maintaining structural integrity under mechanical stress. With an operating temperature range from -40°C to 125°C, it performs reliably across a wide range of Australian installation environments.

This product also aligns with multiple international standards including AS/NZS 4325 Part 1, IEC, DIN/VDE, JIS, and BS, helping electricians maintain compliance on regulated installations where certified components are required.

Trade-Ready Design That Saves Time on Site

For busy electricians and contractors, installation efficiency matters. The CABAC bi-metal sector link is engineered with the realities of site work in mind. The hex die crimp compatibility eliminates the need for specialised crimp tooling, helping crews complete terminations faster with tools already in the van.

This makes it a practical solution for switchboard connections, URD networks, and distribution installations where aluminium cables must interface with copper systems. With fewer installation complications and a design optimised for four-core sector conductors, electricians can complete connections quickly and move on to the next stage of the job.

Available through iSupply Electrical’s trade-focused range, contractors get fast access to compliant components backed by competitive wholesale pricing and reliable supply when projects are on tight schedules.
