Changdi Power Equipment Co., Ltd. is a professional manufacturer with over 10 years of experience in lightning protection and grounding solutions. Our main products include copper bonded grounding rods, copper clad steel flat bars, copper clad steel round conductors, exothermic welding products, grounding accessories, copper busbars, and grounding enhancement materials. Supported by advanced production facilities, strict quality control procedures, and ISO-certified management systems, our products are exported to customers worldwide.
Our Copper Clad Steel Flat Bar is manufactured through a continuous molecular bonding process, creating a permanent metallurgical bond between high-purity copper and a low-carbon steel core. The copper layer thickness can be customized according to international standards and project requirements, ensuring excellent electrical conductivity, superior corrosion resistance, and high tensile strength.
Compared with traditional galvanized steel conductors, copper bonded flat bars provide lower grounding resistance, longer service life, and outstanding performance in aggressive soil conditions. They are widely used in substations, power transmission projects, telecommunication towers, solar power plants, railway systems, and lightning protection grounding networks.
