CABAC BI-METAL STALK 70MM2 CABLE BS70/12 x 1/EACH

Description

Reliable Bi-Metal Connection for Aluminium to Copper Terminations

The CABAC BI-METAL STALK 70MM2 CABLE BS70/12 is designed to deliver a secure and efficient transition between aluminium conductors and copper connection points. Built for 70mm² stranded sector and circular stranded aluminium cable, this bi-metal stalk lug provides a dependable termination solution commonly required in switchboards, distribution systems, and industrial installations.

The aluminium barrel is pre-coated with jointing compound, helping reduce oxidation and ensuring a clean, consistent crimp every time. When paired with standard Australian crimp tooling, electricians can achieve a solid electrical connection that maintains conductivity and long-term performance in demanding environments.

Built for Electrical Reliability and International Compliance

Manufactured using 99.6% pure aluminium and 99.95% pure copper, the CABAC bi-metal stalk lug is friction welded to create a strong and consistent bond between the two metals. This construction reduces the risk of joint failure while maintaining excellent electrical conductivity.

Designed to meet multiple international standards, these lugs are suitable for professional installations where compliance and performance are critical. The fully annealed metal construction provides strength while maintaining the ductility needed for reliable crimping.

Compliance includes:

• AS/NZS4325 Part 1

• IEC France

• DIN/VDE Germany

• JIS Japan

• BS United Kingdom

With an operating temperature range of –40°C to +125°C, the lug performs reliably across a wide range of electrical environments, making it suitable for both indoor switchboards and demanding industrial installations.

Trade-Ready Design for Fast Installation on Site

Electricians and contractors need components that install quickly and perform reliably. The CABAC BS70/12 bi-metal stalk lug is manufactured to Australian dimensions, meaning it works seamlessly with standard Australian crimp tooling already used on site.

Each lug is individually packed, helping keep components clean and protected during transport and storage. This practical packaging makes it easier for contractors to manage stock on site and reduces the risk of contamination before installation.

With a full range of sizes available across the CABAC lineup—and the ability to machine custom stalks when required—these lugs provide a dependable solution for contractors working on switchboard builds, commercial electrical installations, and large-scale power distribution projects.
