CABAC BI-METAL LINK 70AL TO 25CU BLK70/25 x 1/EACH

Description

Reliable Aluminium-to-Copper Connections for Critical Installations

The CABAC Bi-Metal Link 70AL to 25CU BLK70/25 is designed to provide a secure transition between aluminium and copper conductors in demanding electrical installations. Ideal for joining 70mm² aluminium cable to 25mm² copper cable, this bi-metal link ensures dependable conductivity where mixed conductor types are used across switchboards, mains connections, and distribution systems.

Manufactured using friction-welded aluminium and copper, the link provides strong mechanical integrity and excellent electrical continuity. This construction helps reduce resistance at the joint, maintaining system efficiency and ensuring reliable current flow across the connection.

For electricians working on commercial fit-outs, industrial infrastructure, or large residential supply connections, the BLK70/25 provides a practical solution when transitioning between aluminium mains and copper sub-circuits.

Built for Compliance and Long-Term Connection Integrity

CABAC’s range of bi-metal crimp links is manufactured to Australian dimensions, allowing compatibility with Australian standard crimp tooling used by electricians across the country. This ensures straightforward installation without the need for specialised tools, helping reduce time spent on site.

Each link is produced using 99.6% pure aluminium and 99.9% pure copper, delivering reliable conductivity and long-term durability in electrical systems. The barrels are pre-coated with jointing compound, helping minimise oxidation and corrosion at the connection point—an important factor when joining dissimilar metals such as aluminium and copper.

Individually packed in protective plastic bags, every link arrives clean, protected, and ready for installation, maintaining product integrity from warehouse to job site.

Designed for Efficient Trade Installation

When projects are running on tight schedules, electricians need components that install quickly and work first time. The CABAC BLK70/25 bi-metal link supports fast installation with a straightforward crimp connection suitable for stranded sector aluminium and circular stranded aluminium cables joined to stranded copper conductors.

Its compatibility with standard crimp tooling means contractors can complete connections efficiently without slowing down the job. The individually packaged links also make it easy to store and transport in vans or site toolkits without contamination or damage.

For electricians managing multiple projects, using trusted connection components like the CABAC bi-metal link helps reduce the risk of call-backs, maintain compliance with installation standards, and keep jobs moving without delays.
