CABAC BI-METAL LUG 120MM2-STD12MM BL120-12 x 1/EACH

Description

Reliable Bi-Metal Lug Performance for Aluminium Conductors

The CABAC BL120-12 Bi-Metal Lug is engineered for dependable termination of 120 mm² stranded sector and circular stranded aluminium conductors. Manufactured using 99.6% aluminium and 99.9% copper, the aluminium barrel and copper palm are friction welded to create a strong, electrically sound connection that maintains conductivity under demanding conditions.

The barrel is chemically treated and pre-filled with jointing compound, helping break oxide layers on aluminium conductors while reducing contact resistance. When crimped correctly from the palm end first, the compound is driven into the conductor strands to improve electrical contact and long-term performance.

For electricians working on switchboards, mains connections, and heavy-duty installations, this bi-metal lug delivers the solid conductivity and dependable termination required on site.

Built for Compliance and Long-Term Reliability

CABAC’s bi-metal lug range is manufactured to meet recognised international and Australian standards, helping ensure installations meet compliance requirements across residential, commercial, and industrial projects.

The friction-welded aluminium-to-copper joint prevents electrolysis between dissimilar metals, protecting the connection from corrosion and degradation over time. Combined with a fully annealed metal state and high tensile strength, the lug provides durability even in demanding environments.

With operating temperatures from –40°C to 100°C, it is suitable for a wide range of electrical installations where consistent performance and compliance are essential.

Designed for Fast, Efficient Trade Installation

The BL120-12 is designed for standard Australian crimping tools using normal aluminium hexagonal dies, making it easy to install without specialised equipment. Tooling compatibility across CABAC, Utilux, and Burndy systems provides flexibility for electricians already equipped with common tooling.

This practical compatibility helps reduce installation time on site and avoids unnecessary tooling changes. For contractors managing tight schedules, reliable components like this help keep jobs moving and minimise downtime during terminations or switchboard work.
