China Electric Power Transformer Maintenance Equipment Insulating Oil Vacuum Drying and Filtering Machine

China Electric Power Transformer Maintenance Equipment Insulating Oil Vacuum Drying and Filtering Machine

Product Description

Electric power transformer maintenance equipment insulating oil vacuum drying and filtering machine


This machine is mainly used for regenerating the electrical insulating oil such as transformer oil, switch oil and mutual inductor oil, especially suitable for the regeneration of seriously deteriorated insulating oil.

1.Besides the common vacuum oil purifier’s function of dewatering, degassing and eliminating impurities, this machine can regenerate the seriously deteriorated oil by removing the polarity materials such as the deep oxides, free carbon in the oil effectively. It can recover the seriously deteriorated oil to comprehensive index of anti-alkali and water-solubility etc.

2.Three ways of service: use only vacuum dewatering, degassing, removing impurities system; use only the regeneration system independently; and also can use both at the same time.



It can not only remove water, gases and impurities from the unqualified insulating oil and improve voltage withstanding value, but also can remover many values to the national standard such as the acid value, PH value etc. Meanwhile, it can filtrate out the free carbon, deep oxides and so on to comprehensively improve various properties of insulating oil.
