What are the advantages of grounding modules over grounding poles

2021-07-29

The grounding module is a grounding body mainly made of non-metallic materials. It is composed of non-metallic materials with low resistance and stable chemical properties and anti-corrosion metal electrodes.

The advantages of the grounding module are as follows:

1) The main body of the grounding module itself is made of anti-corrosion material, and its metal frame adopts a metal material with anti-corrosion treatment on the surface, so the overall anti-corrosion performance of the grounding body is excellent, and the service life can reach more than 30 years. It can absorb moisture, keep effective contact with the soil, and has low grounding resistance.

2) The non-metallic material of the grounding module forms a relatively smooth low-resistance area between the metal and the soil with a huge difference in resistivity. When a large current impacts, it can reduce the transient potential gradient of the grounding body and the grounding wire and reduce the stride. Voltage and contact voltage reduce the probability of ground potential counterattack.

3) The grounding module itself has strong moisture absorption and moisturizing ability to keep the soil around it moist, ensuring that the grounding module can effectively perform the conductive role; at the same time, the conductive properties of the conductive objects in the grounding body are not affected by seasonal changes such as dry humidity, high and low temperatures, etc. Influence. Therefore, stable ground resistance can be provided.

4) The main material of the grounding module is similar to the physical structure of the soil and can be integrated with the soil. The effective contact area of the grounding body and the soil is many times larger than that of the 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, so it can significantly improve the grounding efficiency and reduce the ground network occupation Land area.
