Hermetically Sealed Type Transformer

Hermetically Sealed Oil Type Distribution Transformer

   This type of transformer is a transformer that uses transformer oil as the electrical short circuit insulation in the transformer. The transformer oil is also used for cooling the inside coils to the outside of the transformer. The transformer tank is sealed hermetically to prevent air coming into and contact with the oil inside the transformer. Therefore, this type of transformer provides great ability to prevent moisture. As a result, the transformer oil will not easily deteriorate. It also helps maintain the insulation of transformer oil to last longer, and lengthen the duration and reduce the cost of the transformer maintenance as well. Generally, this type transformer will be installed outdoor.
