Hermetically Sealed Oil Type Distribution Transformer

This type of transformer uses transformer oil as an insulator to prevent short circuits inside the transformer and release heat from inside the coil to the outside area. The tank itself is carefully sealed to prevent external air from leaking inside and mixing with the oil. There are 2 types of fin; corrugated fin and radiator fin. This type of transformer, therefore, is highly capable of withstanding moisture and deteriorates at a slower rate. It will also help preserve the quality of the insulator of transformer oil as well as extend the durability and reduce maintenance costs. This type of transformer is mainly installed outdoors and cable box is the optional accessories.
