CABAC BI-METAL STALK 120MM2 CABLE BS120/12 x 1/EACH

Description

Reliable Bi-Metal Cable Lug Performance for Aluminium Conductors

The CABAC Bi-Metal Stalk 120mm² Cable Lug BS120/12 is designed for secure termination of stranded sector and circular stranded aluminium conductors in demanding electrical installations. Manufactured using 99.6% pure aluminium sleeves and 99.9% pure copper palms, this lug provides efficient conductivity while ensuring a strong mechanical connection between aluminium cable and copper equipment terminals.

The aluminium barrel comes pre-coated with jointing compound, helping minimise oxidation and improving long-term electrical performance once crimped. With a 120mm² nominal conductor capacity, this bi-metal lug delivers reliable current transfer and strong mechanical retention when used with standard Australian crimping tooling.

Built for real-world site conditions, the lug operates across a wide temperature range from –40°C to +125°C, making it suitable for indoor switchboards, industrial equipment connections, and outdoor installations.

Friction-Welded Strength and Standards-Compliant Reliability

CABAC manufactures these lugs using a friction welding process in accordance with IEC standards, permanently bonding the aluminium sleeve and copper palm to create a durable, low-resistance joint. The result is a high-strength connection capable of withstanding electrical loads and mechanical stress commonly encountered on commercial and industrial projects.

With 110 MPa tensile strength and fully annealed metal construction, the lug maintains excellent ductility for reliable crimping while maintaining structural integrity. Electrical performance is equally dependable, with high conductivity ratings of 61.8% IACS for aluminium and 99.7% IACS for copper, supporting efficient current flow across the termination.

The BS120/12 lug is manufactured to meet recognised international standards, including AS/NZS4325 Part 1, IEC France, DIN/VDE Germany, JIS Japan, and BS United Kingdom, giving electricians confidence that the component meets compliance expectations across regulated installations.

Trade-Ready Termination Solution for Faster Installations

For electrical contractors working under tight project timelines, reliability and ease of installation matter. The CABAC BS120/12 bi-metal stalk lug is designed to integrate seamlessly into standard Australian installation practices, allowing electricians to terminate aluminium conductors quickly using standard crimp tooling.

Each lug is individually packed in plastic bags, protecting the jointing compound and ensuring clean, ready-to-use components when they arrive on site. This helps minimise prep time and prevents contamination before installation.

Available through trade wholesalers supporting nationwide delivery, these lugs allow contractors to source compliant termination hardware quickly for switchboards, distribution systems, and infrastructure work—keeping projects moving without unnecessary delays.
