This oil purifier is a maintenance system for transformers and Transformer oil. ZYD transformer oil filter can keep transformers and transformer oil in a normal and good running condition. So that to save the new oil cost and transformers replacement cos


This oil purification plant is applied to filter various of unqualified insulation oils including aging transformer oil, insulation oil, specially for the power which is above 110KV, mutual inductor oil, switch oil and so on. Also it can inject the insulating oil into the transformers on-line.


1. Double-stage High Vacuum dehydration and degassing and removing impurities from the used transformer oil.

2. Eliminate acidity, sludge, free carbon, discoloration elements, and other soluble matters in the oil, which decays the transformer.

3. It can vacuum filling oil to transformers, and it can vacuum dry transformers and on-line operation with transformer.

4. The standard ZYD system is designed for purifying and filtering oils in workshops, in storage tanks or directly in transformers (energized or de-energized transformers).

The oil technical data after treatment:

1. Gas content is less than 0.1%

2. Impurity size is less than 1μm without free carbon

3. Water content is less than 3 part per million

3. Oil dielectric strength (breakdown voltage) is more than 75KV

4. Acidity value is less than 0.01 mg KOH/g

5. Dielectric loss factors at 90°C is less than 0.001
