CCS-Copper Clad Steel Strand

Dead Soft Annealed (DSA) Copper Clad steel (CCS) conductors are a concentric lay-stranded construction. The CCS strands are a 40% conductivity grade of material using a low carbon steel core rendering greater flexibility to enable easier handling during installation.

Application

Copper clad steel wire (CCS Wire) 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.

DSA Copper Clad Steel stranded conductors 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.
