S11 series fully sealed oil-immersed power transformer has the advantages of low loss, low noise and efficiency, which can achieve good energy-saving effect and reduce pollution. Compared with the ordinary oil-immersed transformer, the fully sealed transformer eliminates the oil storage tank, the oil volume change is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated tank, the transformer is isolated from the air, prevents and slows down the deterioration of the oil and insulation aging, enhances the operation reliability, and the normal operation is maintenance-free.
