Transformer Oil Degassing Machine CMM-6/7 with Two-Stage Vacuum System

More details - . The transformer oil degassing machine CMM-6/7, designed for both hermetic and non-hermetic transformers, offers deep oil degassing and vacuum oil filling. Its distinctive feature is a two-stage vacuum system, consisting of backing and booster pumps for high vacuum creation. The unit operates in multiple modes, the main ones being degassing, drying, and filtration of transformer oil, facilitated by a three-stage filtration system ensuring high removal efficiency of mechanical impurities. The CMM-6/7 operates at a capacity of 6 cubic meters per hour in these modes. It ensures a breakdown voltage of insulating oil of 70 kilovolts, gas content below 0.1%, and moisture content under 10 grams per ton. Additionally, a tape heater is used for transformer flushing with hot insulating oil, and a vacuum system operates during transformer vacuumizing. The machine is equipped with various sensors for detecting abnormal situations, such as oil leaks, foam generation, and
