CABAC BIMET SECTOR LINK 240/4/25 BLKS240/4/25 x 1/EACH

Description

Reliable Bi-Metal Sector Link Performance for Aluminium to Copper Connections

The CABAC Bimetal Sector Link 240/4/25 is designed to provide a secure and efficient connection between sector aluminium cables and circular copper conductors. Built for 3 and 4 core cable applications, this link allows electricians to confidently transition between aluminium distribution cables and copper termination points without compromising electrical performance.

The aluminium sleeve and copper palm construction delivers excellent conductivity and dependable current transfer, making it well suited for switchboards, distribution equipment, and industrial installations. With friction welding used to permanently bond the metals, the connection point remains strong and electrically stable across demanding operating conditions.

This combination of aluminium and copper ensures reliable conductivity while maintaining mechanical strength, helping contractors achieve consistent performance across both new installations and retrofit projects.

Built for Compliance, Durability, and Long-Term Electrical Reliability

Electrical installations require components that meet strict compliance and durability standards. The CABAC bi-metal sector link is manufactured using high-purity aluminium and copper, ensuring dependable electrical properties and consistent conductivity across the joint.

With a fully annealed metal state and friction-welded joint construction, the connector provides strong mechanical integrity while maintaining stable electrical performance under load. The link operates across a wide temperature range from -40°C to 125°C, making it suitable for a variety of Australian environments including commercial switchrooms, industrial plants, and outdoor electrical infrastructure.

Compliance with recognised international standards including AS4325 Part 1, IEC, DIN/VDE, JIS, and BS provides additional assurance that the connector meets the quality and safety expectations required on professional electrical installations.

Trade-Ready Cable Links That Keep Installations Moving

For licensed electricians and contractors, the right connector can make the difference between a smooth installation and unnecessary delays. The CABAC BLKS240/4/25 bi-metal sector link simplifies the process of joining aluminium sector cables to copper conductors, helping streamline termination work in switchboards, distribution boards, and heavy-duty power systems.

Using proven friction-welded technology and high-grade conductive materials, the connector is designed to deliver consistent performance with minimal maintenance. This helps reduce the risk of connection failure, overheating, or downtime on site.

Supplied by iSupply Electrical alongside a large trade-grade range of electrical components, this product supports contractors who need reliable parts quickly to keep projects on schedule.
