CABAC BIMET SECTOR LINK 185/4/95 BLKS185/4/95 x 1/EACH

Description

Reliable Aluminium-to-Copper Connections for Heavy-Duty Installations

The CABAC Bi-Metal Sector Link 185/4/95 is designed to create a secure electrical connection between solid or standard sector aluminium cables and circular copper conductors. Built for demanding commercial and industrial installations, this bi-metal link ensures consistent conductivity while maintaining mechanical strength in critical power distribution applications.

The link features an aluminium sleeve paired with a copper palm, providing the correct transition between different conductor materials. This design helps reduce connection resistance and supports efficient current flow, making it suitable for high-load circuits where performance and stability are essential. With friction welding used to join the aluminium and copper components, the connection is structurally strong and built to withstand the mechanical stresses often encountered in switchboards, distribution panels, and heavy electrical infrastructure.

Engineered for Compliance and Long-Term Reliability

Electrical contractors need connectors that meet recognised standards and perform reliably across varying environmental conditions. The CABAC Bi-Metal Sector Link is manufactured using high-purity conductive metals, ensuring excellent conductivity and dependable performance across long service life cycles.

The aluminium sleeve is manufactured from 99.6% aluminium, while the copper palm is 99.95% copper, delivering strong electrical performance with minimal resistance. The components are fully annealed, including the joint, improving ductility and reducing the risk of cracking during installation or operation. Designed for tough electrical environments, the link operates across a wide temperature range from −40°C to 125°C, making it suitable for installations exposed to heat variations in switchboards, plant rooms, and industrial sites.

Compliance with major international electrical standards including AS4325 Part 1, IEC, DIN/VDE, JIS, and BS helps ensure installations meet regulatory expectations and specification requirements on commercial projects.

Built for Trade Efficiency on Site

For electricians and contractors working under tight project schedules, dependable connection hardware can make a real difference on site. The CABAC Bi-Metal Sector Link simplifies aluminium-to-copper terminations, helping reduce installation time while maintaining a safe and compliant electrical connection.

Whether you’re working on switchboard builds, distribution upgrades, or large-scale electrical installations, using a purpose-built sector link helps avoid unreliable field modifications or improvised connections. The result is a cleaner installation, fewer callbacks, and greater confidence that the connection will perform over the long term.

Sourced from CABAC, a trusted name in electrical connection products, this link is suited to professional electricians who need dependable components that integrate easily into demanding projects. With fast ordering and reliable supply through trade wholesalers, it’s a practical solution for keeping jobs moving without unnecessary downtime.
