CABAC BI-MET LUG 4 CORE SECT 185MM BLSC185/4-12 x 1/EACH

Description

Reliable Termination for 185mm² 4-Core Sector Aluminium Conductors

The CABAC BI-MET Lug BLSC185/4-12 is purpose-built for terminating 185mm² four-core solid sector aluminium conductors, making it ideal for underground residential distribution (URD) and heavy-duty electrical infrastructure work. Its specialised barrel design features a sector-shaped internal profile with a round external aluminium sleeve, allowing installers to use conventional hex crimp dies rather than nest-and-indent tooling.

This design simplifies installation on site while delivering strong mechanical and electrical performance. With a friction-welded aluminium sleeve and copper palm, the lug provides a dependable transition between aluminium conductors and copper termination points, ensuring consistent conductivity and a secure connection in demanding electrical installations.

Built for Electrical Compliance and Long-Term Performance

Manufactured using 99.6% pure aluminium for the sleeve and 99.95% pure copper for the palm, this bi-metal lug is designed to maintain stable electrical performance and durability over time. The friction welding process, compliant with IEC standards, ensures a strong metallurgical bond between materials while maintaining excellent conductivity across the joint.

The lug operates reliably across a wide temperature range of -40°C to 125°C, making it suitable for a variety of outdoor and infrastructure installations. Compliance with recognised standards including AS/NZS4325 Part 1, IEC, DIN/VDE, JIS, and BS ensures the product meets international performance expectations while supporting installations that must meet Australian compliance requirements.

For contractors working on infrastructure, distribution networks, and large commercial electrical projects, this level of compliance helps reduce risk while ensuring installations meet specification requirements.

Trade-Ready Installation That Saves Time on Site

Designed specifically for solid four-core aluminium sector conductors, this CABAC lug helps streamline termination work on URD and similar distribution installations. The round external barrel design allows electricians to use standard hex crimp dies already found in most toolkits, eliminating the need for specialised crimp tooling.

For contractors managing tight project timelines, this reduces setup time, simplifies termination procedures, and helps keep installations moving efficiently. The lug can also be used when joining four-core aluminium sector conductors to conventional stranded copper conductors, providing flexibility when transitioning between cable types.

Available through iSupply Electrical with trade-friendly pricing and reliable stock availability, this component helps electricians source the correct termination hardware quickly—keeping projects on schedule and reducing downtime caused by missing parts.
