Copper Clad Steel Wire
Copper Clad Steel Wire
APPLICATIONS
Copper Clad steel wire and strand combines the electrical characteristics of copper with the mechanical properties of steel. Often used for buried ground grid systems, overhead ground wire and messenger wire, it can resist mechanical damage during installation, as well as electrical damage during a fault condition. Copper Clad steel has virtually no scrap value, and is extremely difficult to cut with traditional wire and cable cutting tools, greatly reducing the potential of theft.
CONSTRUCTION
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.
