Product features: Oil Immersed Power Transformer 4000kVA 35kv use insulating oil as cooling and insulating medium.
The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor.
Vacuum oil injection process is adopted to effectively prevent oxygen and water from penetrating into transformer oilresulting in the decline of insulating oil performance.
It is a new generation of energy-saving and environmental protection products.
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.
