The WSK-2 (TH) temperature and humidity controller with imported high-performance temperature and humidity sensors is suitable for monitoring multiple parts of the cabinets of operating mechanism boxes, central switch cabinets, handcart switches and other equipment. Since the selected imported sensor is particularly sensitive to condensation, it can automatically switch on the heater power when it is wet or about to dew to prevent creepage and flashover accidents caused by moisture or condensation under high voltage. Once the moisture is dry, the heating is automatically stopped.

 

The long-term operation of the power system applied to the switchgear proved that the product has obvious effects of moisture-proof, anti-condensation, temperature control, stable and reliable performance, and can replace similar imported products. The product has been widely adopted by major power design institutes, power plants, major power supply bureaus across the country, and many well-known domestic power equipment and switchgear manufacturers.
