Oil immersed series transformer
 

S11-M series fully sealed oil immersed power transformer developed and produced by chaotai power has the advantages of low loss, low noiseand high efficiency, which can achieve good energy-saving effect and reduce pollution. Compared with the ordinary oil immersed transformer, the fullysealed transformer cancels the oil conservator, and the changeof oil volume is automatically adjusted and compensated by the elasticity of thecorrugated sheet of the corrugated oil tank. The transformer issolated from the air, so as to prevent and slow down the deterioration of oil andinsulation aging, enhance the operation reliability, and avoid maintenance in normal operation.
