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

1. Double-stage High Vacuum dehydration and degassing and removing impuritiesfrom the used transformer oil.
2. Eliminate acidity, sludge, free carbon,discoloration elements, and other soluble matters in the oil, which decays thetransformer.
3. It can vacuum filling oil to transformers, and it can vacuumdry transformers and on-line operation with transformer.
4. The standardZYD system is designed for purifying and filtering oils in workshops, in storagetanks or directly in transformers (energized or de-energized transformers).

The oil technical data after treatment:
1. Gas contentis 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 dielectricstrength (breakdown voltage) is more than 75KV
4. Acidity value is less than0.01 mg KOH/g
5. Dielectric loss factors at 90°C is less than 0.001

Zhongneng oil purifier is the most efficient and economical purificationsystem.
