Product Description
The S11-M series hermetically sealed oil-immersed power transformers developed and produced by ourcompany have the advantages of low loss,low noise and high efficiency,which can achieve good energysaving effect and reduce pollution.Compared with ordinary oil-immersed transformers,hermetically sealedtransformers eliminate the oil conservator,and the change of oil volume is automatically adjusted andcompensated by the elasticity of the corrugated sheets of the corrugated oil tank.The transformer is isolatedfrom the air to prevent and slow down the deterioration ofoil and insulation aging,enhance the reliability ofoperation,and maintain normal operationwithout maintenance.
