Product Description

Application: Bimetallic lug are mostly useful where an aluminum cable has to be terminated by a copper busbar or copper contact. Technique of production:friction welding.  The transition section between aluminum and copper is produced by friction welding,bending 180°,no  breaking welding. Barrels are supplied capped and filled with jointing compound to avoid oxidation of the aluminum conductor.
