I. Introduction casting copper grounding electrode is the introduction of advanced plating process from production, it has a copper layer thickness (0.254 mm or more), low resistance, corrosion resistance, high strength, easy installation, electrical connection resistance, good adhesion, no peeling, (can be rolled thread) and so on. The first is characterized by its tensile strength (greater than 600 N / mm2). Corrosion resistance (guaranteed service life of 30 years), there is a certain low resistance and good plasticity, both high conductivity copper has properties of both steels. Plating process to produce a series of products to overcome the defects of poor adhesion coating method sleeve, and even copper-clad steel grounding grounding device can be widely used in power transmission and communication lines, power plants, buildings and antennas can also be used for computers and other electrical equipment grounding system, and with the air terminals (lightning, lightning line) and deflectors consisting of lightning protection and grounding devices. Second, the technical advantages of a unique manufacturing process: the use of the country's first horizontal continuous casting production process to achieve metallurgical weld between the copper and steel. Can be like pulling a single metal, like any drawing, does not appear out of line, warping, cracking phenomenon. 2, anti-corrosion properties superior: composite interface with high temperature welding, no residue, combined with surface corrosion does not occur; surface of the copper layer is thick (average thickness greater than 0.254mm) corrosion resistance, long life (over 40 years), reduce the labor intensity overhaul. 3, better electrical performance: Surface copper material excellent electrical properties, and even make their own copper-clad steel grounding resistance value is much lower than conventional materials. 4, widely practicality: This product is suitable for different soil moisture, changes in ground temperature under construction, PH value and the resistivity. 5, the connection is secure: Use a dedicated connection tube or using hot-melt welding, the joint firm, good stability. 6, easy installation and quick: complete accessories, easy to install, can effectively improve the speed of construction. 7, improving ground Depth: special connection transmission mode, can be 35 meters deep underground, in order to meet the requirements of low resistance for special occasions. 8, low construction cost: Compared with the traditional use of copper grounding rods, grounding strap construction methods, the cost dropped significantly. Third, the scope and even copper clad steel grounding electrode material for use in special circumstances the general environment and humid, saline, acidic soils and produce chemical corrosion medium, widely used in power plants, substations, transmission line towers, communication base stations, airports , railway, subway stations, a variety of high-rise buildings, microwave relay stations, network room, petrochemical plants, oil storage facilities and other places of lightning protection and grounding, anti-static grounding, protective grounding, grounding work.
