3 Phase Distribution Transformer Application

The 3 phase 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 35kV 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 of 2500kVA (single-phase maximum rated capacity of 833kVA, generally not recommended to use single-phase transformers), and can be used indoors (outdoors). When the 3 phase distribution transformer capacity is 315kVA and below, it can be installed on the pole, the ambient temperature is not higher than 40°C, not lower than -25°C, the highest daily average temperature is 30°C, the highest annual average temperature is 20°C, and the relative humidity is not more than 90% 25°C). Altitude does not exceed 1000m. If it is inconsistent with the above conditions of use, 3 phase distribution transformer should be adjusted according to the relevant provisions of GB6450-86.
