[Qinghai Tongchuan Material Copper Clad Steel grounding lightning protection and grounding hospital dedicated] Circle Line Circle Line Copper Clad Steel grounding soft state and hard state is divided into two kinds, the former using the turntable into a shaft packing, generally 100 m / disk, hard state line is a straight line , generally 6 m / roots. Single Copper clad steel grounding Circle Line is I am using electroplating, continuous casting production process of the new grounding, using the most advanced technology will be 99.9% pure copper surface coverage to a special steel core made of conductive properties of copper rod with the same diameter same, but the cost is much lower than copper, corrosion resistance far superior to galvanized steel, with good conductivity, low resistance, excellent corrosion resistance, easy to transport, easy construction, construction efficiency advantages, is an alternative to round steel, angle, galvanized flat steel and other traditional materials, the best choice for grounding.
