DTL series of copper-aluminum wiring terminals are suitable for transition connection of the
circular aluminum wires, hemicyce-sector aluminum wires, power supply cables in the distri-
bution equipment and copper terminals of the electrical equipment. The material of aluminum
and copper are that of L3 and T2 respectively. The technology of friction welding is wonderfully
adopted. Therefore they have distinguishing features of strong weld intensity, good nature in
electrification, resistant galvanic corrosion and long service life.
