Distribution transformer is one of the important industrial and mining enterprises

Distribution transformer is one of the important industrial and mining enterprises and civil equipment for power distribution systems, oil immersed power transformer will be 10 (6) kV or 35kV network voltage falls below 230 / 400V bus voltage users. Such products applicable to the exchange 50 (60) Hz, three-phase maximum rated capacity 2500kVA (single-phase maximum rated capacity of 833kVA, is generally not recommended to use a single-phase transformers) may, within households (outside) the use,oil immersed distribution transformer capacity 315kVA and below can be mounted on the rod, the ambient temperature is not higher than 40 ℃, not lower than -25 ℃, the highest daily average temperature of 30 ℃, the highest annual average temperature of 20 ℃, relative humidity less than 90% (ambient temperature 25 ℃), altitude not more than 1000m. If inconsistent with the above conditions, according to relevant provisions of GB6450-86, and make appropriate quota adjustments.
