Today, the editor in charge of graphite grounding will talk about the characteristics of graphite grounding modules. Firstly, graphite grounding modules are divided into plum blossom grounding modules, cylindrical grounding modules, zeolite grounding modules, and square grounding modules.
Advantages of graphite grounding module products:
1. The main material of the graphite grounding module has a similar 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.
2. The graphite grounding module itself has strong moisture absorption and retention ability, keeping the surrounding soil moist and ensuring the effective conductivity of the grounding module; 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 non-metallic material of the graphite grounding module creates 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 counterattack.
4. The main body of the graphite grounding module itself is made of corrosion-resistant material, and its metal skeleton 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.
5. The grounding module can be vertically or horizontally buried, with a burial depth generally ranging from 0.8 to 1.0 meters. The metal grounding body has strong moisturizing, moisture absorbing, and stable conductivity. The contact resistance between the metal grounding body and the ground through the non-metallic module material on the periphery will be greatly reduced, achieving good resistance reduction effect.
