Copper Clad Steel Wire (CCS)
1. Application
It is used in frequency coaxial cable, messenger wire, telephone drop-wire and distribution wire;
It is used as the lead-wire for electronics, carrying wire for railroad and wire for power transmission;
It is used in bind wire, jewellery chain, piano string cover and pipe insulation wire.
2. Section diagram
CCS wire is formed through electroplating method(taking steel wire as the core and depositing the copper layer evenly on the surface
of the steel core) and cladding method (Cladding planished copper stripe concentrically on the outer surface of the steel core).
3. Advantages
l Anti-corrosion. 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.
l 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% to 70% copper can be saved using copper-coated steel wire instead of pure copper wire.
l 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.
