Product Description
Oil Immersed Transformer Banner
OIL-IMMERSED TRANSFORMER
S11-M series fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, which can achieve a 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 sheet of the corrugated oil tank. The transformer is isolated from the air, so as to prevent and slow down the deterioration of oil and insulation aging, enhance the operation reliability, and avoid maintenance during normal operation.
