Application:
Copper clad steel has been widely used in fields of communication, electron, power and traffic engineering,Ground wires;telephone, telegraph, and railway signal line, etc.
Direction:
Copper clad steel conductor is a kind of composite bimetal wire with copper facing which feature high intensity, high electric conductivity and high stability .Copper clad steel is available with either in two tempers -soft(A) and as drawn(H).
