Product Overview
High-Performance Bimetallic Transition Lugs
These bimetallic lugs are specifically designed for the transition connection between aluminum or aluminum alloy cables and copper ends of electrical equipment in medium voltage applications. Manufactured using a high-strength friction welding process, they ensure a reliable bond between the aluminum barrel and copper palm to prevent galvanic corrosion. Each unit comes pre-filled with jointing compound and features clear markings for precise crimping according to DIN standards.
