As is well known 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.

The FUOOTECH Vacuum Transformer Oil Filtration Machine (Series ZYD-EX) has been specially designed for on site use to completely regenerate insulating oils in energized or de-energized transformers even when transformer power both below and above 100kva, 110KV and altitude over 500 meters, as well as purify mutual inductor oil, switch oil and so on. Also it can inject the insulating oil into the transformers on-line and dry the transformer.

The ZYD-EX system not only provides regular oil purification/ reclamation such as degassing, drying and particulate removal, but also can remove acidity, sludge, carbon deposits, sulfur, and other soluble oil decay products and improve physical & chemical properties comparable to new transformer oil.

This type oil filtration is also specially designed for explosion proof, applied with complete explosion proof measure and operated in some dangerous area. The explosion proof class is normally ExdBT4, CT class is also available to design. It can meet requirement in various dangerous environments.
