DTL-2 Bimetal cable lug
A cable lug for mounting on the end of a cable for making electrical connection between a conductor of the cable and other electrical equipment. The lug includes a palm for connecting the lug to the electrical equipment, a generally elongate cylindrical barrel for receiving therein one end of the cable conductor, and an insert for disposal within the barrel and for extending around and along the inner surface of the barrel to align the lug more concentrically on smaller cables, preferably with the barrel being conveniently made with uniform wall thickness.
Bimetallic lug are mostly useful where an aluminum cable has to be terminated by a copper busbar or copper contact.
Technique of production:
The transition section between aluminum and copper is produced by friction welding, no breaking welding.
Barrels are supplied capped and filled with jointing compound to avoid oxidation of the aluminum conductor.
Material: 99.9% purity copper & 99.5% purity aluminum.
Final treatment: Acid cleaning
