CABAC BI-METAL LUG 25MM2 12MM STUD BL25-12 x 1/EACH

Description

Strong Electrical Performance for Aluminium Conductors

The CABAC BL25-12 Bi-Metal Lug is designed to deliver dependable electrical connections when terminating 25mm² stranded aluminium conductors. Manufactured using high-purity aluminium and copper, the lug is friction welded to create a strong, electrically sound bond between the aluminium barrel and copper palm.

The barrel is chemically treated to reduce contact resistance and corrosion while being pre-filled with jointing compound that breaks oxide layers on aluminium conductors. When crimped from the palm end first, the compound is forced through the conductor strands, helping achieve a secure, low-resistance connection that performs reliably in demanding installations.

Built for Reliability and Standards Compliance

For contractors working on compliant installations, the CABAC bi-metal lug is engineered to meet recognised international standards. The friction-welded joint prevents electrolysis between aluminium and copper components, helping maintain long-term connection integrity in switchboards, distribution systems, and industrial applications.

Manufactured using 99.6% pure aluminium and 99.9% pure copper, the lug offers strong conductivity and durability across a wide operating temperature range. The fully annealed metal state improves ductility, while compatibility with standard aluminium hexagonal dies ensures consistent crimps using commonly available Australian tooling.

Trade-Ready Installation with Standard Tooling

The BL25-12 lug is designed with the trade in mind, allowing fast and reliable installation on site. It is compatible with standard Australian crimp tooling, with interchangeable tooling between CABAC, Utilux, and Burndy systems—making it easy to integrate into existing toolkits without additional equipment.

Whether you’re terminating aluminium feeders in switchboards, connecting distribution equipment, or completing commercial power installations, these lugs help keep jobs moving without delays. Reliable stock availability and fast delivery through iSupply Electrical also means contractors can source the components they need quickly to keep projects on schedule.
