[Halfback Gansu nonmetal mine equipment grounding module AAA grade standards] metallic grounding module, compared with the traditional grounding, this product has high efficiency and reduction in resistance, grounding resistance stability and reduce back ground, long life, corrosion resistance, non- toxic environmental protection, construction and easy installation, widely used in lightning protection and grounding, safety grounding, grounding exchanges, DC working grounding, anti-static grounding, shielding, grounding, and other special ground. Non-metallic ground module works and the role of the grounding resistance ground network mainly by grounding the material itself and its connection resistance grounding contact resistance with the surrounding soil and into the ground current diffusion resistance in the soil composition, wherein the ground and soil contact resistance and current in the soil into the ground diffusion current is a major part of earth resistance, grounding resistance accounted for 98% or more. The traditional multi-metal grounding conductor, such as flat steel, round steel, angle iron, steel, copper rod, copper and so on. Grounding material made using traditional ground network influenced by the seasons, grounding resistance is not stable enough, to network relatively short life, particularly in the soil resistivity under conditions of high ground is difficult to solve the problem. Botou City Jinyuan Lightning Protection Equipment Co., Ltd. was established in 2002, is located in Chengdu Industrial Development Zone Company headquarters, is a new type of lightning electromagnetic pulse protection and grounding materials, new energy products, electricity parameter detection, measurement and other products R & D, manufacturing, marketing, design and construction of high-tech enterprises.
