CABAC BI-METAL LUG 50MM2-STUD12MM BL50-12 x 1/EACH

Description

Reliable Bi-Metal Connection for Aluminium Conductors

The CABAC BL50-12 Bi-Metal Lug is designed for secure termination of stranded sector and circular stranded aluminium conductors in demanding electrical installations. Manufactured from 99.6% pure aluminium with a 99.9% copper palm, the lug delivers excellent conductivity while providing a strong and stable transition between aluminium cable and copper connection points. The aluminium barrel is pre-filled with jointing compound, helping break down oxide layers during crimping to improve conductivity and ensure a dependable electrical connection. When installed correctly—crimping from the palm end first—the compound is forced into the conductor strands, helping create a solid, low-resistance termination suited to professional electrical work.

Built for Compliance and Long-Term Performance

For contractors working on residential, commercial, or industrial projects, compliance and durability matter. The CABAC bi-metal lug uses a friction welding process to permanently bond the aluminium sleeve and copper palm, creating a strong, electrically sound joint that resists electrolysis and corrosion over time. The barrel is also chemically treated to reduce contact resistance and corrosion, helping maintain performance in challenging environments. Designed for trade use, the lug supports installations that require dependable electrical performance and adherence to international standards.

Standards and compliance include:

• AS/NZS 4325 Part 1

• IEC (France)

• DIN/VDE (Germany)

• JIS (Japan)

• BS (United Kingdom)

This makes the BL50-12 suitable for professional electrical installations where reliability and compliance are essential.

Designed for Fast, Trade-Friendly Installation

On busy job sites, efficiency matters. The CABAC BL50-12 is designed to be crimped using standard Australian tooling, allowing electricians to use normal aluminium hexagonal dies without needing specialised equipment. Tooling compatibility across CABAC, Utilux, and Burndy systems helps streamline installation and reduces the need to carry additional tools on site. The robust construction and straightforward crimping process make it a practical choice for contractors working across switchboards, distribution systems, and industrial installations. Available through iSupply Electrical, electricians and contractors can quickly source reliable connection hardware with competitive trade pricing and fast delivery across Australia—helping keep projects moving without unnecessary delays.
