Description
The fully sealed oil-immersed type transformer has the advantages of low loss, low noise, and high efficiency, and can achieve good energy saving effect and reduce pollution. Compared with the ordinary oil-immersed transformer, the fully-sealed oil-type transformer cancels the oil storage tank, 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, preventing and slowing down the deterioration of oil and insulation aging. , Enhanced operational reliability, maintenance-free normal operation.
