CABAC BI-METAL LUG 25MM2-STD 10MM BL25-10 x 1/EACH

Description

Strong, Low-Resistance Connections for Aluminium Conductors

The CABAC BL25-10 Bi-Metal Lug is designed to deliver a dependable connection between aluminium conductors and copper termination points. Built with a 99.6% pure aluminium barrel and 99.9% pure copper palm, the lug is joined using a friction welding process that produces a strong, electrically sound joint. The aluminium barrel is pre-filled with jointing compound that breaks down oxide layers during crimping, ensuring improved conductivity and lower contact resistance. This makes installation faster while helping maintain reliable electrical performance on residential, commercial, and industrial installations where aluminium conductors are used.

Built for Compliance and Long-Term Reliability

For contractors working to strict compliance requirements, the CABAC bi-metal lug range meets multiple international standards, giving confidence on both commercial and infrastructure projects. The friction-welded joint helps prevent electrolysis between aluminium and copper, supporting long-term connection stability. The barrel is chemically treated to further reduce corrosion and contact resistance, improving durability in demanding environments. With operating temperatures ranging from -40°C to 100°C, these lugs are suitable for a wide range of electrical installations where reliability and compliance are critical.

Trade-Friendly Installation with Standard Tooling

The BL25-10 lug is designed to work with standard Australian crimping tools and aluminium hexagonal dies, making it easy to integrate into existing site workflows without specialised tooling. When crimped from the palm end first, the jointing compound is forced through the conductor strands, helping achieve a secure and efficient termination. Tooling compatibility across CABAC, Utilux, and Burndy systems adds extra flexibility for contractors already equipped with industry-standard equipment. For busy electricians managing multiple jobs, this means faster installations, fewer tool compatibility issues, and reliable results every time.
