Ⅰ. What is a ground module?


The ground module is a ground body with carbon material as the main body. It is composed of non-metallic minerals with good conductivity and stability. The ground modules can be divided into many types according to the products' shapes, including the plum-shaped ground module, cylindrical ground module, square ground module, and so on.


Ⅱ. The advantages of the ground module


1. The main material of the ground module is similar to the physical structure of the soil and can be integrated with the soil. The effective contact area between the ground body and the soil is many times larger than that of the metal ground body, which increases the effective dissipation area of the ground body and greatly reduces the contact resistance between the ground body and the soil. Therefore, it can significantly improve the ground efficiency and reduce the occupation of the ground network.


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


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


4. The main body of the ground module is made of anti-corrosion material, and its metal frame adopts anti-corrosion treatment on the surface, so the overall anti-corrosion performance of the ground body is excellent, and the service life can reach more than 30 years.


5. The ground module can be embedded vertically or horizontally, and the embedded depth is generally 0.8 to 1.0 meters. It has strong moisture retention, moisture absorption and stable conductivity. The metal ground body passes through the peripheral non-metallic module material, and the contact resistance with the earth will be greatly reduced, achieving a good resistance reduction effect.
