Problems solved by technology

[0008] 1) There are copper wires (belts), copper clad steel (including electroplated copper, etc., continuous casting copper) lightning protection grounding wires. Although the corrosion resistance performance has been improved for general medium soil environments, it still cannot meet the requirements of certain specific organic media. Corrosive environment, because once the product is formed, it cannot change its surface corrosion resistance to specific corrosive media, and a large amount of copper is buried in the soil, if it does not match the background metal content of the original soil environment, the soil environment of the area will be used polluted
[0009] 2) There are galvanized steel materials supplemented by a large amount of resistance reducing agent to reduce the grounding resistance, but in the construction of complex climate environment (alpine, severe cold, etc.), it is basically unable to meet the construction requirements, and the reliability of the electric welding joint At the same time, the resistance reducing agent may also cause corrosion to the grounding steel material, and the welding point cannot be guaranteed against corrosion
[0010] 3) Some grounding modules or ion-type grounding bodies are used. Such products are not only expensive, but also develop the grounding body in depth, and the construction cost will be greatly increased
And this type of method uses metal materials as the main frame of the grounding system---the main material, and the main material is used as the basis of the system grounding to connect and constitute the main frame of the electrical connection. The corrosion resistance and conductivity of the connection end are stable. The performance is subject to the construction skills and quality of the on-site construction personnel, and the unstable factors are extremely large
At the same time, all ionic materials have the problems of corrosion to the main material metal and contact resistance cannot be guaranteed
[0011] 4) There is a simple lightning protection grounding method that uses galvanized steel profiles as the main material of the lightning protection grounding device, but it has been considered unsuitable for the above-mentioned heavy corrosion fields in the industry, and is only limitedly used in extremely common requirements Lightning protection grounding system for buildings
