Better electrical performance:the surface layer of copper-clad steel strand is oxygen-free copper,which has good electrical conductivity.The inner layer is high-quality carbon steel.
It is widely applied in power transmission line,electrified railway carrier cable,lightning protection earthing and other field.
It is composed of pure copper layer and steel core.
