Copper-clad steel electrode is a kind of composite metal conductor made from copper and steel throughspecial process. It belongs to grounding material with features: good grounding effect, low-cost and convenientinstallation, and perfectly combinesgroundingconductivitycorrosion resistance and higherperformance price ratio.While applying to lightning protection grounding device , the conductivitycooper-clad steel is very close to pure copper because of the skin effect of high frequency current. The copperlayer thickness can adapt to the corrosion of the environment by adjusting the manufacturing process, whichwill ensure the equipment keep normal operation in the whole life cycle. The steel used has a certain tensilestrength, can be located into the soil directly, which is very easy to installation. Copper-clad steel electrodeapplies for grounding fields such as lightning& grounding protection and high voltage electrical equipmentprotection. Product technical parameters complies with the specified requirements of DL/T 1312 Specificationsfor copper clad steel in power engineering grounding
