Why are some transformers oil filled?

Transformer oil, or insulating oil, is usually a highly-refined mineral oil that is stable at high temperatures and has Excellent electrical insulating properties. It is used in oil-filled Transformers, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage switches and circuit breakers. Its functions are to insulate, suppress corona and arcing, and to serve as a coolant.

After Transformer oil is used for a long-period, the oil will turn to dark liquid. The Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as an effective dielectric.

Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. Also there are some waste impurities, gas contents in the transformer oil which destroy the oil's quality.

Hi-tech Vacuum Transformer Oil Purification Systems is the most efficient and economical purification system.

Hi-tech Vacuum Transformer Oil Purification Systems is applied to filter various of unqualified insulation oils including aging transformer 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.

Hi-tech Vacuum Transformer Oil Purification Systems has the great abilities in removing impurities, particles, water content, gas content, acid, etc... making the waste transformer oil to be regenerated to new oil's quality for reuse.
