CABAC BI-MET 4 CORE SECT LINK AL185 TO CU150MM BLKSC185/4/150 x 1/EACH

Description

Built for Reliable Aluminium-to-Copper Terminations

The CABAC Bi-Metal 4 Core Sector Link AL185 to CU150mm² is designed to efficiently join sector-shaped aluminium conductors to copper cables in demanding electrical installations. Built specifically for four-core solid sector aluminium conductors, this link allows electricians to transition from aluminium URD cables to conventional stranded copper conductors with confidence.

The aluminium barrel features a circular external design with a sector-shaped internal profile, enabling reliable crimping using standard hex dies rather than specialised nest-and-indent tooling. This makes installation faster on site while maintaining a strong mechanical and electrical connection—ideal when working on underground distribution networks and commercial supply connections.

For contractors handling aluminium feeder cables, this bi-metal sector link provides a practical solution that simplifies terminations and ensures dependable conductivity across dissimilar metals.

Proven Compliance and Electrical Performance

Designed for trade environments where compliance matters, the CABAC bi-metal sector link is manufactured from high-purity aluminium and copper and joined using friction welding in accordance with IEC standards. This process delivers a robust bond between metals, reducing the risk of failure in critical connections.

The aluminium sleeve (99.6% purity) and copper palm (99.95% purity) provide strong conductivity and durability across a wide range of operating conditions. With an operating temperature range from -40°C to 125°C, the connector performs reliably in both indoor switchboards and outdoor distribution environments.

Compliance with international and regional standards including AS/NZS4325 Part 1, IEC France, DIN/VDE Germany, JIS Japan, and BS United Kingdom gives contractors confidence that the component meets recognised electrical performance and safety requirements.

Trade-Friendly Installation for URD Projects

Electricians working on URD installations, switchboard upgrades, or supply transitions often need fast, dependable aluminium-to-copper connections. The CABAC bi-metal sector link is engineered specifically for these tasks, reducing installation complexity while ensuring consistent results.

Because the connector supports conventional hex crimp dies, installers can use the same tooling already carried on most service vehicles. This eliminates the need for specialised equipment, helping keep projects moving and reducing downtime on site.

Available through iSupply Electrical’s trade-focused supply network, contractors benefit from reliable stock availability, competitive wholesale pricing, and fast delivery across Australia, ensuring the parts you need arrive when the job demands them.
