​Under effect of heat and electric field, the exposure of insulation oil contained trace water, gas and particulate matters etc.
 The use of Vacuum Transformer Oil Purifier (Model SINO-NSH VFD) is necessary, which will help you maintain optimal oil cleanliness. VFD series is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matters etc. from the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system. VFD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.
