CABAC BIMET SECTOR LINK 240/4/70 BLKS240/4/70 x 1/EACH

Description

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

The CABAC BI-Metal Sector Link 240/4/70 is designed to safely connect sector-shaped aluminium conductors to circular copper cables, making it a practical solution for mixed-metal terminations in power distribution systems.

The aluminium sleeve and copper palm construction allows electricians to join dissimilar conductors without the risk of galvanic corrosion that can occur when aluminium and copper are directly connected. This link is suitable for 3-core and 4-core cable applications, providing a dependable transition point when working with aluminium supply cables and copper equipment connections. The friction-welded joint ensures strong electrical continuity while maintaining mechanical strength, helping deliver consistent performance in demanding electrical installations.

Built for Compliance, Safety, and Long-Term Reliability

Manufactured with high-purity aluminium and copper, this bi-metal sector link is engineered for conductivity, durability, and compliance across international electrical standards. The friction welding process used to join the aluminium sleeve to the copper palm ensures a solid bond between metals, improving mechanical integrity and electrical performance under load. Designed to operate in a wide temperature range from -40°C to 125°C, the link remains stable in varied site conditions, whether used in switchboards, industrial infrastructure, or commercial installations.

Compliance with globally recognised standards—including AS4325 Part 1, IEC, DIN/VDE, JIS, and BS—provides electricians confidence that the connector meets recognised electrical and safety requirements.

Trade-Ready Components That Keep Projects Moving

For contractors managing tight installation schedules, reliable connectors are essential. The CABAC BI-Metal Sector Link is designed for quick, straightforward integration into cable termination workflows, helping reduce delays during switchboard assembly or cable jointing. Whether you’re working on commercial fit-outs, infrastructure upgrades, or industrial distribution systems, these sector links support efficient cable transitions between aluminium supply cables and copper terminations commonly used in equipment and switchgear.

Stocking trusted trade-grade products like this ensures electricians can complete installations efficiently while maintaining compliance and long-term reliability in their electrical systems.
