NSH VFD series Double-Stage High-Efficiency Vacuum Transformer Oil Purifier is mainly used to filtrate ultra high voltage transformer oil (above 110kv), unused oil, imported oil, mutual inductor oil, and some expensive oils such as transformation system capacitor oil, and refrigerated oil, etc. This purifier can also be used in vacuum injection and drying treatment of transformer. 

NSH VFD series Double-Stage High-Efficiency Vacuum Transformer Oil Treatment Plant is mainly used to improve the properties of insulation oil. It can remove minim water, gas, mechanical impurities etc. from the insulating oil effectively so as to increase special indexes of insulation oil.

NSH VFD series Double-Stage High-Efficiency Vacuum Transformer Oil Purifier combined vacuum flashing evaporation technology and delaminating gradual-close filter technology. Based on the vacuole theory, contact area of liquid oil expands to hundreds times than before in the Vacuum Separator. And vacuole system continually makes the evaporation surface of oil expand. So that the oil flows track and static water evaporation area were expanded to the largest extent. The particular double-stage vacuum separator and pressure-boost technical make vacuum degree in vacuum pot higher than that in common oil purifier plant. It removes water, gas, sludge etc. efficiently and effectively and reduce dielectric loss and acid value under lower temperature to increase oil flash point and breakdown voltage hugely as well as to decrease media wastage and acid value. The breakdown voltage of unused oil can be changes from below 25KV to over 75KV under the whole treatment. In this way, the installation period and maintenance period can both be shortened effectively.
