Vacuum Insulation Oil Dehydration and Degassing System,Two Stage Vacuum Transformer Oil Purifier is widely used for industries of power plant, power station, electricity company, transformer factory, metallurgy, petrochemical, mechanical engineering, transportation, railway and transformers manufacturing etc.

Especially, it applies to maintenance of transformers above 110KV and deep purification of high grade new transformer oil, imported transformer oil, mutual inductor oil and ultra high voltage transformer oil. It can be also used for oil vacuum filling and vacuum drying as well as transformer vacuum evacuation operation. Moreover, the machine can be working online without stop of transformers.

Application

It can quickly and effectively remove moisture, gas (Hydrogen, acetylene, methane, etc.) and impurities from the insulation oil, to improve the oil dielectric performance. The filtered oil can effectively ensure the power equipment run safely and normally. 

ZYD Double-stage vacuum oil purifier,Vacuum Insulation Oil Dehydration and Degassing System is widely used in power supply, power generation, power transmission and transformation, power equipment manufacturing, power engineering, electrical equipment maintenance, power testing, electrical research and other industries. It is especially suitable for the filtration of high-grade transformer oil and ultra-high transformer oil, and can be applied to online oil filtering operations at the power substation (like 110KV / 220KV / 500KV). 

Meanwhile, It has the functions of vacuum drying, vacuum oil injection, and hot oil circulation. It can also be used as a separate vacuum pumping unit to evacuate transformers and power equipment.
