CABAC BIMETAL SW/GEACHR CONN 35MM2 BSC35/12K x 1/EACH

Description

Reliable Aluminium to Copper Termination for Switchgear Connections

The CABAC Bi-Metal Switchgear Connector 35mm² (BSC35/12K) is purpose-built for terminating aluminium conductors onto 12mm copper switchgear stems, making it a dependable choice for commercial and industrial installations. Designed for stranded sector and circular stranded aluminium conductors, this connector provides a secure mechanical and electrical connection where aluminium cable needs to interface with copper equipment.

The connector features a bi-metal lug friction-welded from high-purity aluminium and copper, ensuring strong conductivity and long-term current transfer. The aluminium barrel is supplied pre-coated with jointing compound and sealed with a protective cap, helping prevent oxidation and ensuring consistent contact performance during installation. For switchboard builds, plant upgrades, or distribution system work, this connector delivers the reliable aluminium-to-copper transition electricians need without compromising conductivity or installation efficiency.

Built for Compliance, Conductivity & Long-Term Performance

Engineered with 99.6% pure aluminium and 99.9% IACS copper, the CABAC bi-metal connector provides excellent conductivity while maintaining mechanical strength and durability in demanding electrical environments. The friction-welded joint (IEC standard) creates a solid metallurgical bond between the aluminium and copper components, reducing resistance and maintaining performance over time.

A steel clamping collar with allen head grub screw secures the 12mm switchgear stem inside the machined copper stalk, applying firm pressure for effective current transfer. The collar is zinc-plated and split to prevent eddy currents, helping minimise heat generation and maintaining safe operating conditions. The connector is manufactured to Australian dimensions and recognised international standards, ensuring compatibility with common switchgear installations and compliance with established electrical specifications used across Australian projects.

Designed for Fast Trade Installation

Time matters on site, and the CABAC BSC35/12K connector is designed to work with standard Australian crimping tools, making installation quick and straightforward for electricians and switchboard builders. The sealed aluminium barrel with jointing compound eliminates extra preparation steps, helping reduce installation time and ensuring consistent connections.

For contractors handling switchboard terminations, distribution upgrades, or industrial electrical installations, this connector provides a dependable solution that keeps projects moving without unnecessary delays. Available through iSupply Electrical’s trade-focused range of electrical components, electricians can source reliable, compliant products quickly — whether ordering online for delivery across Australia or collecting from local trade counters.
