ST ascending Thai grounding module block is a non-metallic materials as the main body of the grounding body, it has conductivity, stability of non-metallic minerals and metal electrodes composed of better. Main characteristics: 1, resistance reduction characteristics, grounding module using non-metallic conductive material as the main agent, is an inorganic physical type of resistance reduction, no chemical pollutants. Resistivity as low as 0.15Ωm. 2, long-lasting properties, grounding module used non-metallic conductive substances with good chemical and biological stability, to ensure that the use of liters of Thai 50 years after the use of effective, grounding module material itself more than 50 years of life. 3, corrosion characteristics, the grounding module wrapped in the metal electrodes, isolation of the soil oxygen and moisture contact with the grounding electrode, which greatly reduces the rate of corrosion of the metal electrode, especially in saline and alkaline soils, and the metal electrode. Especially when used in saline soil, the effect is more obvious, after excavation tests, the grounding body surface to form a steel gray passivation film, no signs of corrosion of the grounding body, and passivation film has a further role in protecting the grounding body from corrosion. According to customer requirements, the module in the middle of the metal electrode replaced by copper and other corrosion-resistant highly conductive metal, so that life expectancy of more than 50 years.
