CABAC BI-METAL LUG 800MM2-BLANK BL800 x 1/EACH

Description

High-Performance Bi-Metal Lug for Large Aluminium Conductors

The CABAC BI-METAL LUG 800MM² – BL800 Blank is designed to provide a strong, reliable termination when connecting large aluminium conductors to copper busbars or equipment terminals. Manufactured from 99.6% aluminium and 99.9% copper, the lug uses a friction-welded joint to create a highly durable electrical connection between the aluminium barrel and copper palm. This construction ensures excellent conductivity while preventing the galvanic corrosion that can occur when dissimilar metals meet. The aluminium barrel is chemically treated to reduce contact resistance and corrosion, and it is pre-filled with a jointing compound that helps break oxide layers on aluminium conductors.

For large-scale installations and high-current applications, this design supports consistent electrical performance and dependable long-term operation.

Built for Compliance and Long-Term Electrical Reliability

CABAC bi-metal lugs are engineered to meet recognised international standards, giving electricians confidence in both safety and performance on site. The friction-welded joint provides a mechanically strong and electrically sound connection that maintains conductivity over time without risk of electrolysis. The lug is fully annealed for ductility, allowing it to handle the stresses of crimping and installation without compromising structural integrity. When installed correctly—crimping from the palm end first—the jointing compound is forced through the conductor strands to ensure maximum contact and improved electrical continuity.

Manufactured to meet multiple global standards including AS/NZS 4325 Part 1, these lugs are suitable for demanding electrical installations where compliance and long-term reliability are essential.

Trade-Friendly Installation with Standard Tooling

Designed with working electricians in mind, the CABAC BL800 bi-metal lug can be crimped using standard Australian aluminium hexagonal dies, making installation straightforward with common industry tooling. Tooling compatibility across CABAC, Utilux, and Burndy systems helps streamline work on site without requiring specialised equipment.

For contractors handling switchboards, distribution infrastructure, or industrial power installations, this lug supports efficient installation and reliable connections on large aluminium conductors. Combined with dependable product availability through iSupply Electrical, trades can source compliant components quickly and keep projects moving without delays.
