To be used for treatment to new oil, imported oil and super HV transformer oil, particularly applicable to 110KV power distribut - details see: https://www.machineto.com/zyd-high-efficient-two-stage-transformer-oil-purifier-10228763

Technical Features:

1. Based on the high efficient vacuum oil purifier, Roots vacuum booster system and secondary high vacuum separation system are added, which enable the vacuum limit reaching ≤5Pa.
2. Being able to remove water and gas fast and effectively under high vacuum and high speed operation status, which achieves satisfactory dryness and could bring the breakdown voltage up to 70KW, resulting in an enhanced one-time filtration effect which reduces the oil aging problem existing with ordinary purifiers as caused by repeated heating.
3. Being able to remove the minimal amount of water and various gases in oil, 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 for pressure protection and power heating system ensures 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 110KV power distribution system and the national grid, shortening the oil treating duration during installation and maintenance of transformer.
