Set value and reduce contact resistance: The graphite material of the graphite ground module is similar to the physical structure of the earth. The buried energy of the grounding module is combined with the soil, making the effective contact area between the grounding body and the soil many times larger than that of metal grounding, thereby increasing the effective stray area of the grounding and greatly reducing the interaction between the grounding body and the soil. contact resistance between. Soil, it can significantly improve grounding efficiency and reduce the topography of the grounding grid.
Secondly, reduce the counterattack of the ground potential: the special material of the graphite ground module will cause a difference in resistivity between the metal and the soil, thus forming a relatively mild low-resistance area. When a large current impacts, it can reduce the transient potential of the connecting body and the ground wire. The graphite material is located between the metal ground body and the soil and plays a certain role in this process.
The grounding module has the ability to absorb grounding moisture. Therefore, keep the soil surrounded by the grounding module moist to ensure the safety of the grounding module. Grounding has an effective conductive effect; at the same time, the conductivity of the conductor in the grounding body is not affected by changes in humidity, high temperature, and low temperature, thus providing stable grounding resistance. The grounding module virtually guarantees the soil resistivity of the same housing structure.
