CABAC BI-METAL LUG 50MM2-STUD10MM BL50-10 x 1/EACH

Description

Reliable Aluminium-to-Copper Termination for 50mm² Conductors

The CABAC BL50-10 Bi-Metal Lug provides a secure and efficient termination when connecting 50mm² aluminium conductors to copper busbars or equipment studs. Designed for stranded sector and circular stranded aluminium conductors, this lug combines a 99.6% aluminium barrel with a 99.9% copper palm to deliver dependable conductivity and mechanical strength on demanding installations. A friction-welded joint bonds the aluminium sleeve to the copper palm, creating a highly durable electrical connection that resists separation under load. The barrel is pre-filled with jointing compound to break down oxide layers during crimping, improving electrical contact and ensuring consistent performance across switchboards, distribution equipment, and power installations.

For electricians working on commercial, industrial, or infrastructure projects, this design supports efficient cable termination while maintaining reliable current flow.

Built for Long-Term Performance and Standards Compliance

CABAC’s bi-metal lug construction is engineered to prevent electrolysis between aluminium conductors and copper connection points, helping maintain connection integrity over time. The chemically treated aluminium barrel reduces contact resistance and improves corrosion resistance, making it suitable for demanding environments. The lug is fully annealed for ductility, allowing it to crimp securely without cracking while maintaining strong mechanical performance with a tensile strength of 110 MPa. Manufactured to recognised international and Australian standards, the BL50-10 supports compliance across professional installations.

Standards and compliance include:

• AS/NZS 4325 Part 1

• IEC (France)

• DIN/VDE (Germany)

• JIS (Japan)

• BS (United Kingdom)

With an operating temperature range of -40°C to 100°C, the lug performs reliably across varied site conditions, helping electricians maintain safe and compliant terminations.

Trade-Friendly Installation with Standard Australian Tooling

The CABAC BL50-10 is designed for straightforward installation using standard Australian aluminium hexagonal dies, making it compatible with commonly used crimping tools across the trade. For best results, electricians should crimp from the palm end first, forcing the joint compound through the conductor strands to maximise electrical contact. Tooling compatibility across CABAC, Utilux, and Burndy systems adds flexibility on site, helping reduce downtime and tool changeovers. Available through iSupply Electrical’s extensive trade-grade range, this lug supports electricians who need reliable components, consistent stock availability, and fast delivery for ongoing projects.
