[Lanzhou Xianyang 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. After a long period of accumulation, our company in Lanzhou, Xianyang and other regions with long-term supply of customers and establish good relations of cooperation, the majority of users, enterprises and institutions alike, Botou Golden Resources Limited is engaged in mine lightning protection equipment engineering design, construction lightning, with the China Meteorological Administration issued a "mine engineering design qualification certificate", "mine engineering construction qualification certificate" and other professional qualifications mine, experienced design and construction teams to professional lightning protection has a profound understanding and deeper knowledge, and timely tracking the latest domestic and international mine developments, the latest standard, regularly organize personnel to participate in professional and technical training, and constantly improve the level of self. All construction personnel are certificates, used construction equipment, equipment to ensure compliance with national building lightning protection design specifications ...
