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. 4,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.
