What Is An Oil Immersed Transformer?

Distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the 10 (6) kV or 35 kV network voltage to the 230/400V bus voltage used by users. This type of product is suitable for AC 50 (60) Hz, three-phase maximum rated capacity 2500 kVA (single-phase maximum rated capacity 833 kVA, single-phase transformer is generally not recommended), can be used indoors (outdoors), can be installed on poles when the capacity is 315 kVA or below, the ambient temperature is not higher than 40 ℃, not lower than -25 ℃, the highest daily average temperature is 30 ℃, the highest annual average temperature is 20 ℃, the relative humidity does not exceed 90% (ambient temperature 25 ℃), and the altitude does not exceed 1000m. If it does not meet the above conditions of use, it should be adjusted appropriately according to the relevant provisions of GB6450-86.
