Category: Our Services Written by Super User

After drying the transformers whose assembly of active part is completed, in the drying furnaces at 120 degrees Celcius are put into tanks and filled with oil in the vacuum chamber. The air entrapped in the transformer tank is removed by the suction effect in the vacuum chamber and this helps penetrate the insulating oil into the active part thoroughly. The oil filled serves as insulation and coolant. Drying process is accomplished according to a predepned program depending upon the rated voltage and power of the transformer.
