1、接地模块的主体材料与土壤的物理结构相似,能与土壤结合为一体。使接地体与土壤的有效接触面积比金属接地体大许多倍,增大了接地体的有效散流面积,

极大降低接地体与土壤的接触电阻,因此能显著提高接地效率,减少地网占用土地面积。

2、接地模块自身有很强的吸湿保湿能力,使它周围的土壤保持湿润,保证接地模块有效发挥导电作用;

同时,接地体中导电物的导电特性不受干湿度、高低温等季节变化的影响。因此能提供稳定的接地电阻

3、接地模块非金属材料使电阻率相差巨大的金属与土壤之间形成一个变化比较平缓的低电阻区域,

当大电流冲击时,可降低接地体接地线暂态电位梯度,降低跨步电压接触电压,减少发生地电位反击的概率。

4、接地模块的主体本身是抗腐蚀材料,它的金属骨架采用的表面经抗腐蚀处理的金属材料,因此该接地体总体抗腐蚀性能优良,使用寿命达到三十年以上。

5、接地模块可进行垂直埋置或水平埋置,埋置深度一般为0.8~1.0米。

具有很强的保湿、吸湿性和稳定的导电性,金属接地体通过外围的非金属的模块材料与大地的接触电阻将大大减小,达到良好的降阻作用。

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 between the ground body and the soil is many times larger than that of the metal ground body, and the effective discharge area of the ground body is increased.
It greatly reduces the contact resistance between the ground and the soil, so it can significantly improve the grounding efficiency and reduce the land area occupied by the ground network.
2, the grounding module has a strong moisture absorption and moisture ability, so that the soil around it remains moist, to ensure that the grounding module effectively plays a conductive role;
At the same time, the electrical conductivity of the conductor in the ground body is not affected by seasonal changes such as dry humidity and high and low temperatures. Therefore, it can provide a stable ground resistance.
3, the non-metallic material of the grounding module causes a relatively gentle low resistance area between the metal and the soil with a huge difference in resistivity.
When the large current hits, it can reduce the gradient of the ground connection and the transient potential of the ground line, reduce the step voltage and the contact voltage, and reduce the probability of the site potential counterattack.
4, the main body of the grounding module itself is an anti-corrosion material. Its metal skeleton uses a metal material with anti-corrosion treatment on the surface. Therefore, the overall anti-corrosion performance of the grounding body is excellent, and its service life has reached more than 30 years.
5, grounding module can be buried vertically or horizontally, buried depth is generally 0.8 ~ 1.0 meters.
With strong moisturizing, hygroscopic and stable conductivity, the contact resistance of metal grounding body to the earth through the peripheral non-metallic module material will be greatly reduced, and a good resistance reduction will be achieved.
