CABAC BI-METAL LUG 70MM2-STUD12MM BL70-12 x 1/EACH

Description

High-Performance Connection for Aluminium Conductors

The CABAC BL70-12 Bi-Metal Lug is designed to deliver a strong, low-resistance termination when connecting 70mm² aluminium conductors to copper busbars or equipment. Manufactured using 99.6% pure aluminium and 99.9% pure copper, the lug is friction-welded to create a highly reliable electrical joint that maintains conductivity and mechanical strength in demanding installations. The aluminium barrel is pre-filled with a jointing compound that helps break down oxide layers on aluminium conductors during crimping. This improves electrical contact and reduces resistance, helping electricians achieve consistent terminations that perform reliably across residential, commercial, and industrial switchboard work.

Built for Reliability and Standards Compliance

CABAC bi-metal lugs are engineered to meet the expectations of professional electricians who require dependable connections that comply with recognised standards. The friction-welded copper palm and aluminium sleeve design prevents electrolysis, making the lug suitable for aluminium-to-copper connections commonly found in distribution boards, switchboards, and heavy cable terminations. Each lug is chemically treated to reduce corrosion and contact resistance, supporting long-term electrical performance even in demanding environments. The product complies with major international and regional standards including AS/NZS4325 Part 1, IEC, DIN/VDE, JIS, and BS, ensuring installations meet the regulatory requirements expected across Australian electrical projects. With an operating temperature range from -40°C to 100°C, the lug is suitable for a wide range of electrical infrastructure applications where reliability and safety are critical.

Designed for Fast, Trade-Friendly Installation

The BL70-12 lug is designed to work with standard Australian crimping tools and aluminium hexagonal dies, helping electricians complete terminations quickly on site without specialised tooling. Tooling compatibility across CABAC, Utilux, and Burndy systems makes it easy to integrate into existing toolkits used by contractors and maintenance teams. For best results, the lug should be crimped starting from the palm end, allowing the joint compound to distribute through the conductor strands for maximum conductivity and secure termination.

For electricians working to tight deadlines, using dependable termination hardware helps avoid rework, failed inspections, and costly downtime—keeping installations moving smoothly from rough-in through commissioning.
