Oil Filled Type Distribution Transformer

Oil filled distribution transformer as named oil immersed transformer or oil cooled transformer, it means the winding of the transformers immersed with transformer oil and the distribution transformer cooling method called oil cooled type.
The rating capacity of the distribution transformer is normally from 30KVA to 200MVA. There are several types of winding connections for oil filled distribution transformer and normally the customers adopt Delta-star connection method, we could make any accept any winding connections according to customer’s requirement.
The advantage of the oil filled distribution transformer is the good heat dissipation because of the oil circulation cooling, the transformer oil has good insulation performance and heat conduction, this advantage could ensure the distribution transformer operates in normal condition for a long time.
