The difference between a fully sealed oil-immersed transformer and a non-hermetic transformer:

The fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving effect and reduce pollution. Compared with the ordinary oil-immersed transformer, the fully sealed transformer cancels the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated oil tank corrugated oil tank, and the transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging, enhance the reliability of operation, and operate normally without maintenance.
