Oil Immersed Power Transformer 4000kVA 35kv
Oil Immersed Power Transformer 4000kVA 35kv is reduced by 30% on average, and no-load current is 70-80% lower. The iron core is made of import high magnetic conductivity, low loss, cold-rolled high-quality silicon steel sheet, which reduces the no-load loss and saves energy significantly. It shows characteristics of high safety and reliability, advanced structure, small dimension, light weight, low noise, low temperature rise, anti-corrosion and reliable anti-leakage measuresto prevent oil leakage.
Products peatures
1.The low-voltage winding is made of full-section copper foil and by special low-voltage winding machine with f-grade insulation.
2.The winding end is sealed and casted with resin, and then shaped by curing to prevent moisture and fouling.
3.Temperature control device: the transformer is equipped with BWDK series signal thermometer, which is embedded in the upper part of the low-voltage coil.The temperature-measuring components can automatically detect and display the working temperature of the corresponding phase coil, and alarm and trip at over temperature .
4.Insulation grade: the insulation grade of transformer can be divided into grades.
