CABAC BIMET SECTOR LINK 70/3/16 BLKS70/3/16 x 1/EACH

Description

Reliable Aluminium-to-Copper Cable Connections for Demanding Installations

The CABAC BI-Metal Sector Link 70/3/16 is designed to provide a dependable connection between solid or standard sector aluminium cable and circular copper cable. This makes it a practical solution for electricians working on installations where aluminium supply cables need to transition to copper conductors.

Featuring an aluminium sleeve and copper palm construction, the link ensures efficient electrical transfer while reducing the risk of galvanic corrosion between dissimilar metals. The friction-welded joint creates a strong, permanent bond between the aluminium and copper components, delivering stable conductivity across the connection point.

For contractors working on switchboard installations, distribution upgrades, or infrastructure projects, these bi-metal sector links help maintain consistent electrical performance while simplifying cable termination tasks on site.

Built for Compliance, Strength, and Long-Term Reliability

CABAC sector links are engineered to meet multiple international electrical standards, giving electricians confidence that the connection is suitable for professional installations where safety and compliance matter.

The fully annealed metal construction improves ductility and workability during installation, helping reduce cracking or damage when crimping. With a tensile strength of 110 MPa and a ductile rating of 28%, the link is built to withstand the mechanical stresses often encountered during cable preparation and termination.

The component also operates across a wide temperature range of -40°C to 125°C, making it suitable for a variety of electrical environments including industrial switchboards, distribution panels, and outdoor infrastructure where temperature fluctuations are common.

Manufactured in accordance with recognised international standards including AS4325 Part 1, IEC, DIN/VDE, JIS, and BS, this sector link supports compliant electrical installations across residential, commercial, and industrial applications.

Trade-Ready Solution for Fast, Efficient Installations

When deadlines are tight and materials need to perform first time, reliable connection hardware matters. The CABAC BI-Metal Sector Link is built for quick integration into cable termination workflows, helping electricians complete aluminium-to-copper transitions without complicated workarounds.

Its design supports straightforward installation with standard crimping practices, reducing time spent preparing cable joints while maintaining electrical integrity. This makes it ideal for contractors handling switchboard upgrades, distribution connections, or infrastructure maintenance where consistent electrical connections and minimal downtime are critical.

Stocking trusted products like CABAC ensures electricians and procurement teams can rely on proven components for day-to-day installations, keeping projects moving without delays caused by incompatible cable connections.
