CABAC BI-METAL LINK 400AL TO 400CU BLK400/400 x 1/EACH

Description

Heavy-Duty Aluminium to Copper Cable Connections

The CABAC BLK400/400 Bi-Metal Link is designed to deliver secure, efficient connections between 400 mm² aluminium and 400 mm² copper conductors. Built for demanding electrical installations, this link provides a reliable transition between dissimilar metals commonly used in large power distribution systems.

Manufactured using friction-welded aluminium and copper, the link ensures optimal conductivity while minimising resistance at the joint. The aluminium section is produced from 99.6% pure aluminium, while the copper section uses 99.9% pure copper, delivering dependable current flow and strong mechanical performance.

For electricians working on switchboards, industrial infrastructure, or large commercial installations, this bi-metal link provides a practical solution for joining aluminium supply cables to copper terminations without compromising electrical performance.

Built for Reliability and Australian-Standard Tooling

The CABAC bi-metal link range is manufactured to Australian dimensions, ensuring compatibility with standard Australian crimp tooling used across the trade. This means electricians can install with confidence using tools already in their kit—no special equipment required.

Each link features barrels pre-coated with jointing compound, helping to reduce oxidation and maintain connection integrity over time. The friction-welded join between aluminium and copper creates a strong, permanent bond that supports long-term electrical performance in demanding environments.

Every unit is individually packed in plastic bags, keeping the connector clean and protected until it reaches the job site—an important detail when working on installations where connection quality matters.

Trade-Ready Convenience for Fast Installations

Designed with real-world site work in mind, the CABAC BLK400/400 link helps electricians complete cable terminations efficiently while maintaining compliance with recognised installation practices.

The connector supports stranded sector and circular stranded aluminium conductors connected to stranded copper cables, making it suitable for a wide range of heavy-duty electrical installations. With a full range of sizes available across the CABAC bi-metal range—and the option for custom machining when required—contractors can easily source the right link for the job.

For busy contractors managing tight schedules and multiple projects, having dependable connectors on hand reduces installation delays and ensures a clean, professional finish on switchboards, distribution systems, and large cable terminations.
