CABAC BIMET SECTOR LINK 120/4/16 BLKS120/4/16 x 1/EACH

Description

Reliable Aluminium-to-Copper Connection for Sector Cables

The CABAC Bi-Metal Sector Link 120/4/16 is designed to create a secure connection between solid or standard sector aluminium cable and circular copper cable. Built with a high-conductivity aluminium sleeve and copper palm, it ensures a dependable transition between dissimilar conductors commonly found in switchboards, distribution systems, and industrial installations. Using friction welding in accordance with IEC standards, the aluminium and copper components are permanently bonded to minimise resistance and ensure consistent electrical performance. The fully annealed metal construction improves ductility and strength, helping electricians achieve a reliable crimp and long-term connection on site.

For contractors handling distribution upgrades or mixed-conductor installations, this bi-metal sector link provides a practical and efficient solution for joining aluminium sector cables to copper systems without compromising performance.

Built for Compliance and Long-Term Electrical Reliability

Electrical installations demand components that meet recognised standards and maintain performance over time. The CABAC bi-metal sector link is manufactured to comply with AS4325 Part 1 (Australia) and internationally recognised standards including IEC, DIN/VDE, JIS, and BS.

The link is engineered with 99.6% aluminium and 99.95% copper conductive materials, providing excellent conductivity and low resistivity for stable electrical performance. With a tensile strength of 110 MPa and a ductile rating of 28%, it is built to withstand installation stresses while maintaining a strong electrical bond. Its operating temperature range of −40°C to 125°C makes it suitable for demanding environments, ensuring connections remain stable across varying site conditions. For electricians working on commercial or industrial systems, this reliability helps reduce the risk of connection failures and costly downtime.

Designed for Fast, Practical Trade Installations

When working on tight project schedules, electricians need connection hardware that installs quickly and performs reliably. The CABAC BLKS120/4/16 bi-metal sector link is designed for straightforward cable termination and efficient installation during switchboard builds, upgrades, or maintenance work. Its sector-to-circular cable design simplifies joining aluminium distribution cables to copper infrastructure, helping contractors avoid time-consuming workarounds on site. The durable construction and dependable conductivity support long-term installations in residential, commercial, and industrial environments.

Available through iSupply Electrical’s trade-focused wholesale range, electricians can quickly source the components they need for ongoing projects. With competitive pricing and reliable supply, contractors can keep jobs moving without delays caused by hard-to-find connection hardware.
