Transformer, Cell, Kiosk
They are produced in the power range of 25 - 5000 kVA, up to 36 kV high voltage level, three or single phase, with oil, natural cooling (ONAN), with idle tap changer or automatic tap changer under load, and can be used both outdoors and indoors. Hermetic oil type distribution transformers are manufactured by filling oil under vacuum, balancing the oil pressure and atmospheric pressure at the desired temperature, and ensuring that the cooling oil does not come into contact with the atmosphere.
In hermetic oil type distribution transformers, internal heat as a result of changing oil pressure due to thermal changes is controlled by the natural expansion and contraction of the boiler wave walls. Mechanical design and manufacturing are done to withstand these effects.
Hermetic oil type distribution transformers have lower heights than transformers with expansion tanks. Therefore, it can be used in smaller areas.
Since the oil in hermetic transformers does not come into contact with the atmosphere, it does not require oil changes at certain periods, as in transformers with expansion tanks.Transformers from 50kVA to 2500 kVA are available from stock.
