Grounding of Chemical Tube: In the previous grounding type, the following important factors are taking into account:
1. The hollow tube used in the grounding of the chemical pipe is provided with a G.I. "Appropriate size" strip and CCM (Crystalline Conductive Mixture) is compressed into the pipe and the pipe is sealed at both ends.
2. CCM is a semi-metal and hollow tube filled with CCM behave like a solid tube and therefore the current carrying capacity increases substantially.
3. The CCM has a high melting temperature of 2500 ° C and unlike coal it will not burn in ashes under high temperatures of 1500 ° c under high fault currents occurring due to phase-to-phase or phase-to-earth failure.
4. The Moisture Factor (Moisture Level) is maintained by Aluminum Silicate surrounding the slug-shaped electrode. Aluminum silicate has the property of absorbing water 13 times its weight and does not dissolve in water. It stays moist and soft throughout life. A minimum rainfall of 2.5 cm in a year makes the wet and moist aluminum silicate for next year and therefore the cycle continues to repeat year of the year. Therefore, due to the quality of aluminum silicate, no additional watering is done, whether in summer, winter or rainy season, ie under any weather conditions.
Conclusion: - The life of chemical grounding according to reports from the US and other countries is more than 15 years without fault records. E) In India, technology is only a few years old and the record of failures is almost insignificant. Properly installed grounding system under the direction of manufacturers can safely guarantee years and years of working life. It does not need any maintenance unlike the grounding of the conventional plate.
