Application
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, 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.
Specifications
CCS bare conductors meet or exceed the following ASTM specifications:
B-910 Standard Specification for Annealed Copper-Clad Steel Wire
B-258 Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors
B-228 Standard Specification for Concentric-Lay-Stranded Copper-Clad Steel Conductors
NOTE: The ampacity rating and the DC and AC resistance of the Copper Clad Steel wire conductor is not equivalent to that of copper conductor.
