 The oven is applied for drying of oil immersed transformers, transformers, capacitors and other products body,comparing the traditional hot air circulation drying, ordinary vacuum drying and low-frequency drying Equipment, the processing time can be shorten about 1/3, energy consumption can be decreased by 30% -50% and after treatment, the minimum water content of insulating materials can be 5ppm. Comparing the investment with the kerosene vapor phase drying oven,it is 25% -45% of that kind.It is with reliable and energy saving process. Transformation of vacuum drying oven is currently used for voltage 220kv and 110kv ,below the power transformer 500kv ,below transformer and other paper-insulated power. Transformer vacuum drying oven is the best choice for drying equipment.

 

Working principle: By vacuuming, the saturated vapor pressure of water in the environment where the coil insulation material is located is increased to make it easier to evaporate from the insulation paper. During this period, it is continuously heated to raise the temperature to ensure water gasification energy, let the water easier to discharge.
