This product is mainly used for the purification and regeneration of unqualified insulating oil,such as transfer oil,circuit breaker oil,mutual inductor oil,capacitor oil,cable oil,and  high-voltage switching oil,etc. It can quickly and effectively remove moisture,gas,machinery impurities and watersoluble acid and other harmful substances in  the oil,raising the flash point and oil pressurevalue.Besides,it can get rid off the oil sludge ,free carbon,bio-plastic substances and insulation materials from the bad oil.Thereby it can effectively reduce the acid value and dielectric loss of oil and  greatly improve the insulating strength of oil to run equipment in safer and more reliable manner .The onsite charged operation could effectively shorten the trandformer installation and its overhauling  time limit
