Bimetallic Lugs are mostly useful where an aluminum cable has to be terminated by a copper bus bar or copper contact. If Cable Lugs of only copper or aluminum are used , a galvanic action occurs due to dissimilar contact. The use of bimetallic lugs thus ensures a technically sound and durable joint. The Aluminum barrel is friction welded to the copper palm thereby achieving the best possible transition between barrel & palm.
Our range of Bimetallic Lugs is having following advantages:
• Material : Conductivity Aluminum Barrel of 60% IACS & Copper Palm 99.6% IACS.
• Final Metal State : Fully Annealed.
• Jointing Method : Friction Welding
• Sizes : 16 Sqmm to 1000 Sqmm
In Bi-Metal lugs barrel of the lug is of aluminium and the head or palm of the lug is of copper. This ensures contact between aluminium cable to terminal lug is of aluminium and contact between terminal lug to copper bus bar or contact is of copper. Thus contact between dissimilar metal is avoided and contact between similar metal is established. Thus Bi-Mettalic or galvanic action is completely eliminated and hence technically sound and durable joint is achieved.
