Product Description

Application Series ZYD Double-stage vacuum Transformer oil purifier machine is special for treating the used cable insulating oil and old transformer oil, mutual oil, switch oil. Comparing with the single stage type, this machine adopts the double stages vacuum system, which can improve the machine working vacuum value highly, so it can remove the water, gas and impurities in insulation oil high-efficiently, increasing the pressure force and quality of oil, make sure the electric device running safely. Also it can inject the insulation oil into the transformers on line, regeneration the seriously deteriorated oil by removing the polarity materials. The machine is specially applied to vacuum filling oil and drying for power transmission equipments that are over **0KV.Also it can fill the insulating oil into the transformer on-line. The oil technical data after treatment:1. Gas content less than 0.1%2. Impurity size less than 1μm without free carbon3. Oil dielectric strength (breakdown voltage) more than *5KV4. Acidity value less than 0.*1 mgKOH/g5. Dielectric loss factors at *0℃ less than 0.**1
