Bimetal lugs are suitable for transition connection of the circular aluminium wires, hemicycles-sector aluminium wires, power supply cables in the distribution equipment and copper terminals of the electrical equipment. They are made of Cu 99. 9% purity and Al 99. 5% purity. The barrel is friction welded to the palm so that the best possible transition between copper palm and aluminium barrel. To avoid oxidization of the aluminium barrels capped are greased. DTL,CAL-A,CAL-BS lugs are different in the shape of palm.DTLL lug is a bolted lug and can be easily installed by a spanner rather than a hydraulic tool.
