Application
Copper Clad Steel Wires are used in place of copper conductors in grounding applications and systems.conductors are classified as follows: Grade 40 HS, Grade 30 HS, Grade 30 EHS, Grade 40 DSA, and Grade 30 DSA.CCS strand wire is divided into soft state and hard state with perfect conductivity, which is a good choice for various industries such as communications, electrical power and electronics.
DESCRIPTION
Copper clad steel wire (CCS) combines the high tensile strength of steel as its core and the conductivity properties of copper as its outer layer. The core material is usually low carbon steel and is typically used as either grounding wire or the inner conductor of coaxial cables.

FAQ
Copper clad steel wire (CCS Wire) is a composite conductor with a continuous copper layer bonded to a steel core. It combines the electrical performance of copper with the tensile strength of steel, making it a cost-effective alternative to solid copper for select grounding, utility, and communication applications.
High Mechanical Strength–Compared with solid copper of similar size, CCS wire can offer much higher tensile strength for long spans, sag control, messenger wire and demanding grounding applications.
Excellent Corrosion Resistance–The copper surface protects the steel core against atmospheric corrosion, moisture and many soil conditions when cladding continuity and installation quality are maintained.
Cost-Effective Solution–By replacing part of the copper with steel, CCS wire can reduce material cost while maintaining sufficient conductivity for many grounding and utility applications.
Long Service Life–Steel strength plus copper corrosion resistance supports long service life when soil chemistry, connectors and electrical duty are evaluated.
Copper clad steel wire (CCS Wire) is common used in Grounding systems,Earthing grids,Lightning protection systems and Bonding conductors.
