CABAC BI-METAL SECTOR LINK 185/3/185 BLKS185/3/185 x 1/EACH

Description

High-Performance BI-Metal Sector Link for Aluminium to Copper Connections

The CABAC BI-Metal Sector Link 185/3/185 is designed to provide a reliable transition between solid or standard sector aluminium cable and circular copper cable, making it ideal for distribution and switchboard installations where mixed conductors are used. The friction-welded aluminium sleeve and copper palm ensure strong electrical continuity while minimising resistance at the joint. With high-conductivity materials and a fully annealed finish, the link delivers consistent electrical performance under demanding load conditions.

For electricians working on commercial switchboards, industrial installations, or large residential developments, this bi-metal link helps maintain efficient current transfer while reducing the risk of overheating or connection failures.

Built for Reliability and Electrical Compliance

When working on critical power distribution infrastructure, connection integrity matters. The CABAC BI-Metal Sector Link is manufactured using 99.6% aluminium and 99.95% copper, delivering excellent conductivity and durability across a wide range of electrical applications. The link is friction welded in accordance with IEC standards, creating a secure bond between the aluminium sleeve and copper palm. This method ensures long-term structural strength and electrical stability even under varying load and temperature conditions. Designed to meet recognised international standards including AS4325 Part 1, IEC, DIN/VDE, JIS, and BS, the product provides confidence that installations comply with recognised electrical specifications used across Australian projects.

Trade-Ready Components That Keep Projects Moving

Electrical contractors need components that install easily and perform reliably on site. The CABAC BI-Metal Sector Link is engineered for quick, secure cable termination, helping reduce installation time when connecting aluminium distribution cables to copper conductors. Whether you’re completing switchboard upgrades, commercial power distribution, or industrial maintenance work, having the right connector on hand prevents costly downtime and rework.

Available through trade-focused electrical wholesalers with fast supply and consistent stock availability, this component helps electricians keep projects moving without delays caused by incompatible cable connections.
