How does a graphite grounding module material usually perform?森萌 tells you!
The grounding module is a grounding body primarily made of non-metallic materials. It is composed of non-metallic minerals and electrolytes with good conductivity and stability. Its unique shape increases the grounding resistance of the grounding body itself. Additionally, it possesses excellent moisture absorption and retention properties, as well as the ability to improve the soil's conductivity around it. This leads to a continuous reduction in grounding resistance, approaching long-term stability.
Key points of its main role in lightning protection and grounding for everyday use:
Reduce Contact Resistance: The graphite material of the graphite grounding module is similar to the physical structure of soil. When buried underground, the grounding module combines with the soil as one, significantly increasing the effective contact area between the graphite grounding body and the soil compared to a metallic grounding body. This enlargement of the effective spreading area of the grounding body reduces the contact resistance between the grounding body and the soil, thereby substantially improving the grounding efficiency and reducing the land area occupied by the ground grid.
Ground Resistance Stability: Graphite grounding modules do not experience fluctuating resistivity due to soil dryness or moisture. The modules possess strong moisture absorption and retention capabilities, keeping the surrounding soil moist, ensuring the effective conductivity of the grounding modules; at the same time, the conductivity properties of the conductive materials in the grounding body are not affected by seasonal changes such as humidity, high and low temperatures, thus providing stable grounding resistance. The use of grounding modules almost guarantees a constant and unchanging soil resistivity value around the modules.
