treatment to new oil ,imported oil and super HV transformer oil,particularly applicable to 110KV power distribution system - details see: https://www.machineto.com/zyd-50-two-stage-vacuum-transformer-oil-purifier-10228624

1.based on the high efficient vacuum oil purifier,roots vacuum booster system and secondary high vacuum saparation system are added. Which enable the vacuum limit reaching ≤5pa.

2.being able to remove water and gas and effectively under high vacuum and high speed operation status ,which achieves satisfactory dryness and could bring the breakdown valtage up to reduces the oil aging problem existing with ordinary purifier as cuased by repeated heating.

3.being able to remove the minimal amount of water and various gases in opil ,thus ensuring zero acetylene existence.the purifier can also serve as vacuum oil filler and dryer for transformer.

4.the advanced infrared level automatic control system.interlocking control foe pressure protection and power heating system ensure long-term safe and reliable operation.

Use:

to be used for treatment to new oil ,imported oil and super HV transformer oil,particularly applicable to 110KVpower distribution system and the national grid,shortening the oil treating duration during installation and maintenance of transformer
