ZY vacuumtransformer oil filtration machine works under the vacuum status, it is a basicrequirement for vacuum oil purification machine, if the working vacuum reach to-0.095MPa, this machine can satisfy the degasification demand. If we use thiskind machine to degassing and dewatering process for the insulating oil, thegas and water content will reduce. If the oil contains much gas, we can see itthrough the vacuum separator viewer, because the oil goes into the vacuum tankwhich is negative pressure, the gas will transgress under the press action. Thetransformer oil filtration machine can easy pump out those gas to air.
