Designed for Stranded Sector and Circular Stranded Aluminium Conductors, the CABAC range of Bi-Metal Lugs is made from the highest quality aluminium (99.6%) and copper (99.9%) and are joined using a friction welding process. This produces a very strong electrically sound joint, which will not be subject to electrolysis. The barrel is chemically treated to reduce contact resistance and corrosion and is filled with a jointing compound, which breaks the oxide layers on the aluminium. When crimping the lug should be crimped from the palm end first, to force the joint compound into conductor strands. They are designed to be crimped using standard Australian tooling, using normal aluminium hexagonal dies.
