CABAC BI-METAL LUG 300MM2-BLANK BL300 x 1/EACH

Description

High-Performance Bi-Metal Lug for Aluminium to Copper Connections

The CABAC BL300 Bi-Metal Lug is engineered to provide a strong, reliable termination when connecting stranded sector or circular stranded aluminium conductors to copper equipment. Manufactured using 99.6% pure aluminium and 99.9% pure copper, the lug is friction welded to create a highly durable electrical joint that maintains excellent conductivity under demanding conditions.

The aluminium barrel is chemically treated to reduce contact resistance and corrosion while being pre-filled with jointing compound that breaks through aluminium oxide layers during crimping. When installed correctly, this ensures a stable connection that supports efficient current flow and long-term performance across distribution and heavy-duty power installations.

Designed for 300mm² conductors, the blank palm configuration provides flexibility where drilling or custom mounting is required on site.

Reliable Construction with International Standards Compliance

CABAC’s bi-metal lug design ensures dependable electrical performance across commercial and industrial installations. The friction-welded aluminium-to-copper joint eliminates the risk of electrolysis, helping prevent long-term degradation in mixed-metal connections.

The fully annealed metal construction provides the ductility required for secure crimping without compromising structural integrity. Combined with high conductivity ratings and robust tensile strength, the lug maintains consistent performance even in demanding environments.

The CABAC BL300 lug is designed in line with widely recognised electrical standards including AS/NZS4325 Part 1, as well as international specifications used across Europe, Japan, and the United Kingdom. This makes it a dependable choice for contractors working on installations requiring compliant and certified components.

Trade-Friendly Installation with Standard Australian Tooling

Built with the needs of electricians and contractors in mind, the CABAC BL300 bi-metal lug is designed to work with standard Australian aluminium hexagonal crimping dies. Tooling is interchangeable with major industry systems including CABAC, Utilux, and Burndy, helping crews use the tools they already have on hand.

During installation, the lug should be crimped from the palm end first, pushing the jointing compound through the conductor strands for optimal contact and reduced oxidation. This straightforward installation process helps reduce termination time on site while ensuring consistent results across switchboards, distribution equipment, and industrial connections.

With reliable construction and trade-compatible tooling, the BL300 lug helps electricians complete terminations efficiently while maintaining electrical integrity.
