Bimetallic cable lug are manufactured using an electrolytic forged copper palm and electrolytic aluminium barrel.These two are joined using friction
welding technology. Bimetallic crimping connectors are used when aluminium cables need to be terminated to the copper contact or when
aluminium cables enter a switchboard or substation for termination. They are also used where there are long main runs andaluminium
cable is a cheaper method to install than copper cable. The aluminium cable is cheaper than copper cables and requires the bimetallic
cable lug to terminate the aluminium cable to a copper busbar or copper cable, so the lug is the change point between aluminium
and copper cables or copper busbar. If cable lugs are made up of only copper or aluminium, a galvanic action occurs due to
dissimilar contact. Thus, bimetallic cable lug are more effective from the perspective of strength & durability.
