CABAC BI-METAL LUG 185MM2-STD12MM BL185-12 x 1/EACH

Description

Reliable Bi-Metal Lug Performance for Aluminium to Copper Connections

The CABAC BL185-12 Bi-Metal Lug is designed for dependable termination of stranded sector and circular stranded aluminium conductors to copper busbars or equipment studs. Manufactured using 99.6% aluminium and 99.9% copper, the lug is joined through a friction welding process that creates a strong, electrically sound bond between the two metals.

This design helps ensure efficient current transfer while preventing the issues commonly associated with dissimilar metal connections. The barrel is chemically treated and pre-filled with jointing compound, which breaks down oxide layers during crimping and improves electrical contact with the conductor strands.

For electricians working on distribution boards, switchboards, and industrial power installations, the result is a secure, low-resistance connection that supports long-term system performance.

Built for Electrical Reliability and Standards Compliance

When reliability matters on site, the CABAC bi-metal lug range delivers proven performance backed by recognised international standards. The friction-welded joint ensures mechanical strength and stable conductivity, reducing the risk of electrolysis between aluminium conductors and copper connection points. The fully annealed construction provides flexibility and durability during installation, while the treated aluminium barrel helps reduce corrosion and contact resistance over time. This lug range complies with multiple international standards including AS/NZS4325 Part 1, IEC, DIN/VDE, JIS, and BS, making it suitable for installations where compliance and safety are essential.

Designed for Fast, Trade-Friendly Installation

The BL185-12 is designed to integrate seamlessly into standard electrical workflows. It is compatible with standard Australian aluminium hexagonal crimping dies and tooling commonly used across the industry, including tooling interchangeable with CABAC, Utilux, and Burndy systems. For best results, electricians simply crimp from the palm end first, which forces the jointing compound into the conductor strands and ensures optimal electrical contact. With reliable stock availability through trade suppliers and compatibility with common crimping tools, this lug helps reduce installation time, minimise call-backs, and keep projects moving on schedule.
