Technical Specifications
Overview
Bimetallic Lug - French Standard (CAUBT)
The CAUBT series bimetallic lugs are specifically designed for the transition connection between aluminum or aluminum alloy cables and copper terminals of low-voltage electrical equipment. Manufactured to the NF C 63-061 French standard, these lugs utilize friction-welding technology to ensure a high-strength bond between the aluminum barrel and copper palm. This construction prevents galvanic corrosion and ensures a reliable, long-lasting electrical connection in power distribution systems.
