CABAC BIMET SECTOR LINK 240/3/240 BLKS240/3/240 x 1/EACH

Description

Reliable Aluminium-to-Copper Connections for High-Capacity Cables

The CABAC Bimetal Sector Link 240/3/240 is designed to safely connect sector-shaped aluminium conductors to circular copper cables, making it ideal for distribution networks, switchboards, and large-scale electrical installations. The bi-metal construction combines an aluminium sleeve with a copper palm, allowing electricians to join dissimilar conductors while maintaining strong electrical conductivity and mechanical integrity.

Manufactured using friction welding in accordance with IEC standards, the joint ensures a durable bond between metals while minimising resistance at the connection point. This provides dependable current flow across connections, helping maintain system performance in demanding electrical environments. With materials engineered for strength and ductility, these links provide consistent crimping results and a secure connection suited for heavy-duty cable terminations.

Built for Compliance and Long-Term Electrical Reliability

Electrical installations demand components that meet recognised standards, especially in commercial and industrial environments. The CABAC bi-metal sector link is manufactured to comply with AS4325 Part 1 (Australia) along with international standards including IEC, DIN/VDE, JIS, and BS, supporting installations that require strict compliance.

The aluminium sleeve offers minimum conductivity of 61.8% IACS, while the copper palm provides 99.7% IACS conductivity, ensuring efficient current transfer across the joint. The fully annealed metal structure delivers a balanced combination of strength and flexibility, allowing the connector to handle installation stress while maintaining performance over time. With an operating temperature range of -40°C to 125°C, the connector performs reliably across varying site conditions, from outdoor distribution installations to industrial switchboards.

Trade-Ready Components That Keep Jobs Moving

When you’re working to tight project deadlines, reliable cable connectors make a big difference on site. The CABAC BLKS240/3/240 sector link provides a practical solution for electricians handling 3-core sector aluminium cables transitioning to copper conductors. Using quality connectors reduces the risk of connection failures, overheating, or rework—saving time and keeping installations compliant. For contractors managing commercial fit-outs, industrial upgrades, or infrastructure installations, these links help maintain efficient workflow and minimise downtime.

Available through iSupply Electrical’s extensive trade-grade range, electricians can source the components they need quickly—whether ordering online for delivery across Australia or arranging trade pickup from Western Sydney locations.
