Braco Aluminium alloy tubular bi-metallic terminals are manufactured out of aluminium of purity equal to or greater than 99.5 % having maximum coductivity not less than 60% IACS. These are anti-corrosive and used for highly corrosive environment. The barrels are kept filled with grease so as to avoid oxidization of the Aluminium. These are designed to accept a variety of conductor forms especially low stranded compacted conductors.
These terminals are mainly used to terminate on copper bus bars. Whenever aluminium links terminated on to copper or copper based alloy terminals without suitable plating, results in the corrossion of the joint over a period leading to higher joint resistance. Bi-metallic terminals are found most reliable and suitable for such connections.
