Copper-Clad Steel Round Wire

Copper-Clad Steel Round Wire is based on a high-quality steel core, uniformly coated with a highly conductive copper layer. This combines the high strength of steel with the excellent conductivity of copper. Its structure ensures excellent electrical performance while also possessing exceptional mechanical strength and tensile strength, making it suitable for complex construction environments. The copper layer provides excellent corrosion and oxidation resistance, extending the product's service life and maintaining stable conductivity even in humid or high-salt spray environments. This product is commonly used in electrical grounding systems, overhead lines, and lightning protection devices, ensuring smooth current conduction while providing reliable mechanical stability. It is an essential material in power and communications engineering.
