Grounding module is a kind of grounding body with carbon data as the main body. It is composed of non-metallic minerals with good conductivity and stability. Chemical stable non-metallic conductor data is selected as the conductive medium of the module, and its conductivity is not affected by the season. The graphite composition of the grounding module is as high as more than 50%. The module itself has strong moisture absorption and moisturizing ability, which can always keep the soil around the grounding module in a quality and moist state, so as to achieve good conductivity. The main data is similar to the physical structure of the soil and can be integrated with the soil, so that the useful contact area between the grounding body and the soil is many times larger than that of the metal grounding body, which increases the useful dispersion area of the grounding body and greatly reduces the contact resistance between the grounding body and the soil, so it can significantly improve the grounding power and reduce the land area occupied by the grounding grid. The cylindrical grounding module itself has strong moisture absorption and moisturizing ability, Keep the soil around it moist to ensure that the grounding module is useful and has a conductive effect.
