Copper clad steel conductors are commonly used in various applications, including power transmission and distribution systems, telecommunications, grounding systems, and electrical grounding rods. The steel core provides structural integrity and helps to reduce the overall weight and cost of the conductor, while the copper layer ensures low electrical resistance and high conductivity.
As the copper-coated steel wire has a steel core with a uniform copper coating, it is highly resistant to corrosion in air. If the wire is of large diameter and is used as aerial line, bare wire can be used without PVC covered.
Small signal transmission decay. There is skin effect in the transmission of high frequency communication signal. The electric signal is transmission signal. The electric signal is transmitted in the outer copper layer. The transmission decay of copper-coated steel wire is as small as pure copper wire. 50%to70% copper can be saved using copper-coated steel wire instead of pure copper wire.
High strength and low density. Since the steel core can enhance the strength of copper-coated steel wire, and the density of steel is lower than that of copper, the size of suspension steel wire can be reduced by using copper-coated steel wire as aerial line.
