Copper Clad Steel wire

Model: CCS
Diameter: 0.10mm~4.00mm
Capacity:300 tons/m
Tensile strength : 290 Mpa – 1500 Mpa
Electrial conductivity: 15-40% ICAS
Elongation: 1%-25%

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).
CCS wire can be divided into six types by conductivity, 15%CCS,18%CCS,21%CCS, 25%CCS, 30%CCS,40%CCS,and two mechanical status: Annealed (A) and Hard drawn(H).

We can supply products with various conductivity and tensile strength upon the requirement of customers.

Furthermore, CCS wire can be processed to be silver plated or tinned CCS wire

Manufacture Standard:
China standard YD/T722-94 ASTM B 869-96,ASTM B 452-93

Features:

As a composite material, the copper-coated steel wire has the combined advantages of both copper-wire and steel wire, namely the conductivity of copper wire and the strength of steel wire. Moreover, it has 3 to 4 times the strength of pure copper wire and 3 to 5 times the conductivity of steel wire. It is being widely used as a new generation communication lines and power transmission cables.

Advantages:

  • 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.
  • 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.
