Bare Copper-Clad Steel Stranded Wire

Bare Copper-Clad Steel Stranded Wire is composed of multiple tightly twisted strands of copper-clad steel wire, combining the advantages of a highly conductive copper layer with a high-strength steel core. Its exposed copper surface ensures excellent current transmission efficiency while also offering exceptional tensile and corrosion resistance. This type of wire is primarily used in power grounding systems, lightning protection systems, and high-voltage transmission lines, ensuring rapid and secure current conduction and equipment safety. Bare Copper-Clad Steel Stranded Wire is widely used in power projects, telecommunications base stations, transmission towers, and railway electrification projects. It is particularly well-suited for environments requiring high electrical conductivity and mechanical strength, achieving stable, secure grounding and efficient current transmission.

High-strength copper-clad steel wire, combining excellent conductivity and mechanical strength for grounding and overhead lines.
