Product model: Industrial dehumidifier

China Southern Power Grid Company Limited (English: China Southern Power Grid Company Limited) China Southern Power Grid is a central enterprise under the supervision of the State-owned Assets Supervision and Administration Commission of the State Council. Headquartered in Guangzhou, China Southern Power Grid is an extremely large state-owned key backbone enterprise related to national security and the lifeblood of the national economy.

China Southern Power Grid uses NAISIDA industrial dehumidifier to control the humidity of power equipment places such as distribution rooms, substations, high voltage rooms and computer rooms. When the relative humidity is greater than 80%RH, it is the highest occurrence period of electrical equipment accidents, which is generally occuring in the humid spring, or the seasonal exchange season when the temperature changes rapidly or the temperature difference between day and night is large (sudden decrease and increase).

After controlling the humidity, it is conducive to improving the air insulation performance of the electrical equipment, reducing the moisture attached to the surface of the insulation material, maintaining the insulation resistance of the electrical equipment, especially the equipment with a long service life and more internal dust accumulation, reducing or even eliminating the phenomenon of insulation breakdown;

On the other hand, controlling humidity can reduce the growth of mold, thus reducing the probability of a large number of mold with high water content adsorbed on the surface of the equipment;

In addition, the humid air will make the conductive metal in the power equipment, the magnetic silicon steel sheet and the metal shell rust, reduce the air humidity can maintain the performance and service life of the equipment, reduce the occurrence of electrical failures.
