1500 kVA Substation Transformer Distribution Three Phase 4160V ANSI IEEE C57

The hermetically sealed transformers can be described as transformers without protectors. The insulating medium in the transformer oil tank is fully enclosed and completely isolated from the air.This design can prevent air from entering the transformer oil tank, thus preventing corrosion and siltation in the medium liquid.
