name:copper clad steel wire Description: it is one kind of bimetallic wire products, which is produced by electroplating a rod of steel core material with copper and then drawing the electroplated rod to obtain the desired wire diameter. It combines the strength of steel with the conductivity and corrosion resistance of copper. It is used where strengths higher than copper are required, and some reduction in conductivity is acceptable. It is widely used in the telecommunications industry for telephone and coaxial television drop wire, and by the electric utility industry for grounding conductor.
