CABAC BIMET SECTOR LINK 70/3/25 BLKS70/3/25 x 1/EACH

Description

Efficient Aluminium-to-Copper Cable Connections

The CABAC Bi-Metal Sector Link 70/3/25 is designed to securely connect solid or standard sector aluminium cable to circular copper cable, making it an essential component for mixed-metal installations. Built with an aluminium sleeve and copper palm, this link allows electricians to transition between conductor types without compromising conductivity or mechanical strength. The friction-welded joint ensures a strong, reliable bond between metals, maintaining electrical integrity across the connection. This helps prevent overheating, reduces resistance at termination points, and keeps installations running efficiently across residential, commercial, and industrial systems.

Built for Reliability and Electrical Compliance

Manufactured using high-purity aluminium (99.6%) and copper (99.95%), the CABAC bi-metal link delivers consistent electrical performance and durability under demanding site conditions. The fully annealed construction provides the ductility required for secure crimping and long-term stability in distribution systems. With compliance across multiple international standards including AS4325 Part 1 (Australia), IEC, DIN/VDE, JIS, and BS, the link supports installations where compliance and safety are critical. Its operating temperature range of -40°C to 125°C ensures dependable performance in a wide range of electrical environments.

Trade-Ready Design for Faster Installations

Designed for electricians working to tight schedules, the BLKS70/3/25 sector link simplifies aluminium-to-copper terminations in multi-core cable installations. The 3-core configuration makes it suitable for common distribution and power cabling applications where reliable metal transition is required. Using the right link reduces the need for improvised connections, helping contractors complete installations faster while maintaining compliance with electrical standards. For projects where reliability and efficiency matter—from switchboard work to power distribution—this CABAC link provides a dependable solution that keeps jobs moving.
