CABAC BI-METAL LINK 500AL TO 400CU BLK500/400 x 1/EACH

Description

Reliable Aluminium to Copper Cable Termination Performance

The CABAC Bi-Metal Link 500AL to 400CU (BLK500/400) is designed to provide a dependable transition between aluminium and copper conductors on demanding electrical installations. Built for stranded sector and circular stranded aluminium to stranded copper cable, this bi-metal crimp link allows electricians to join dissimilar conductors efficiently while maintaining a secure mechanical and electrical connection.

The friction-welded aluminium and copper construction ensures effective current transfer while reducing the risk of connection issues that can arise when joining different conductor materials. For contractors working on large-scale switchboards, distribution systems, or industrial connections, this helps deliver stable performance and long-term reliability on site.

With compatibility for Australian standard crimping tooling, the link integrates smoothly into existing installation workflows without requiring specialised equipment.

Built for Compliance and Long-Term Connection Reliability

CABAC’s range of bi-metal crimp links is manufactured to Australian dimensional standards, ensuring reliable compatibility with commonly used installation tools and cable types across the industry. Each connector is friction welded using high-purity aluminium (99.6%) and copper (99.9%), providing a durable bond between the two metals for stable conductivity and mechanical strength.

The barrels are pre-coated with jointing compound, helping improve conductivity and reduce the risk of oxidation at the connection point. This added protection supports long-term performance in electrical installations where reliability and compliance are critical.

Individually packed in plastic bags, every link arrives clean, protected, and ready for use on site.

Trade-Ready Convenience for Busy Electrical Contractors

Electrical contractors often need dependable connectors available at short notice, particularly on projects where aluminium feeders must be terminated into copper systems. The CABAC BLK500/400 bi-metal link is part of a broad range designed to support common conductor sizes used in commercial and industrial installations.

Where project specifications require something outside standard sizes, CABAC can machine custom links quickly, helping electricians and procurement teams keep projects moving without waiting weeks for specialised components.

For contractors managing multiple jobs, having a reliable bi-metal link solution means faster installs, fewer delays, and confidence that the connection will meet industry expectations.
