TT-FD-A+composite grounding unit graphite grounding resistance reduction module non-metallic grounding module manufacturer

Description :

　　Why is the grounding module called a "grounding treasure"?

　　In engineering, the grounding module is referred to as the "grounding treasure" in impedance reduction products. With such high praise in the industry for grounding modules, what are its characteristics and honors?

　　Advantages of the grounding module of Qingdao Zhongdian Lightning Protection Technology Co., Ltd.:

　　1. The main raw material of the grounding module is non-metallic material, which forms a relatively gentle low resistance area between the metal with a huge difference in resistivity and the soil. When a large current is applied, it can reduce the transient potential gradient of the grounding body and grounding wire, lower the step voltage and contact voltage, and reduce the probability of ground potential rebound.

　　2. The grounding module itself has strong moisture absorption and retention capabilities, keeping the surrounding soil moist and ensuring that the square grounding module effectively conducts electricity; At the same time, the conductivity of the conductive material in the grounding body is not affected by seasonal changes such as dry humidity, high and low temperatures. Therefore, it can provide stable grounding resistance.

　　3. The main material of the grounding module is similar in physical structure to the soil and can be integrated with the soil. The effective contact area between the grounding body and the soil is much larger than that of a metal grounding body, which increases the effective dissipation area of the grounding body and greatly reduces the contact resistance between the grounding body and the soil. Therefore, it can significantly improve the grounding efficiency and reduce the land area occupied by the grounding grid.

　　4. The main body of the grounding module itself is made of corrosion-resistant material, and its metal frame is made of metal material that has undergone anti-corrosion treatment on the surface. Therefore, the overall anti-corrosion performance of the grounding body is excellent, and the service life can reach more than thirty years.
