What is the tensile strength of Copper Clad Steel Flat Wire?

Raytron CCS flat wire achieves tensile strength of 850-1300 MPa depending on the copper-to-steel ratio. This is approximately 3-4× the tensile strength of pure copper flat wire (~300 MPa), making CCS ideal for overhead ground wires, grounding systems, and applications subject to ice loading and wind stress.

What copper coverage ratios are available for CCS Flat Wire?

Raytron offers CCS flat wire with copper coverage ratios of 10%, 20%, and 30% by cross-sectional area. Higher copper ratios improve conductivity (up to 40% IACS at 30% coverage) while lower ratios maximize tensile strength. The most common specification for grounding applications is 20-30% copper coverage.

Can CCS Flat Wire be used for grounding applications?

Yes. CCS flat wire is specifically designed for grounding applications. It provides equivalent corrosion resistance to solid copper in underground environments while offering 3-4× higher tensile strength. CCS grounding conductors have a typical lifespan of 30+ years and cost 20-30% less than equivalent pure copper. It complies with IEEE 80 and IEEE 837 standards for grounding.

Manufacturing Process

This product is manufactured using Clad & Weld process with metallurgical bonding. It is NOT electroplated.

Metallurgical bonding creates a permanent atomic-level connection, ensuring superior reliability compared to electroplating. This enables excellent weldability, resistance to peeling during bending, and stable performance under thermal cycling conditions.
