| Oil immersed transformer(Oil-filled transformer) for the mining industry and civil systems in one of the important equipment, which 10 (6) kV or 35kV network voltage drops below a user to use 230/400V bus voltage. Such products for exchange 50 (60) Hz, three-phase maximum rated capacity 2500kVA (single-phase maximum rated capacity of 833kVA, is generally not recommended to use single-phase transformers) in the household (and beyond) the use of capacity 315kVA and below can be installed in the pole, the ambient temperature is not higher than 40 ¡æ, not lower than -25 ¡æ, the highest daily average temperature is 30 ¡æ, the highest annual average temperature is 20 ¡æ, relative humidity less than 90% (ambient temperature 25 ¡æ), altitude does not exceed 1000m. If it does not match with the above conditions, shall be the relevant provisions of GB6450-86, adjusted for the appropriate scale. |
