2. Stable grounding resistance: The plum blossom type grounding module itself has a strong ability to absorb moisture and keep the soil around it moist, ensuring that the grounding module can effectively perform its conductive function; at the same time, the conductive properties of the conductive objects in the grounding body are not affected by dryness, humidity, It is able to provide stable grounding resistance due to the influence of seasonal changes such as high and low temperatures.
3. Reduce contact resistance: The main material of the plum-shaped grounding module has a similar physical structure to the soil and can be integrated with the soil, making the effective contact area between the grounding body and the soil many times larger than that of the metal grounding body, increasing the resistance of the grounding body. The effective dispersion area greatly reduces the contact resistance between the grounding body and the soil, so it can significantly improve the grounding efficiency and reduce the land area occupied by the ground network.
4. Reduce ground potential counterattack: The non-metallic material of the plum-shaped grounding module forms a low-resistance area with relatively gentle changes between the metal and the soil with a huge difference in resistivity. When a large current impacts, the temporary resistance of the grounding body and grounding wire can be reduced. The state potential gradient reduces the step voltage and contact voltage, and reduces the probability of ground potential counterattack.
