Products? ????? Oil-immersed distribution transformers transformer is one of the important industrial and mining enterprises and civil equipment for power distribution systems, it will be 10 (6) kV or 35kV network voltage drops below 230 users / 400V bus voltage. Such products applicable to the exchange 50 (60) Hz, three-phase maximum rated capacity 2500kVA (single-phase maximum rated capacity 833kVA, generally do not recommend the use of single-phase transformers) may, within households (outside) the use, capacity and below 315kVA 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 of 25 ℃), Altitude not more than 1000m. If inconsistent with the above conditions, according to relevant provisions of GB6450-86, and make appropriate adjustments quota. ? ????? ????? Model interpretation? ????? Features? ????? 1, no conservator height lower than similar products. ????? 2, sealed transformers and transformer conservator with the body of exactly the same, so you can correspond to different models of transformers designed for users to choose. ????? 3, the transformer sealed vacuum oiling process to completely remove the moisture in the transformer. After sealing the transformer oil is not in contact with air, oxygen and moisture effectively prevent immersed transformer insulation performance degradation caused (insulation and oil aging), and therefore do not have regular oil sample test.
