The 200kva fully-sealed oil-immersed transformer developed and produced by our company has the advantages of low loss and low noise, which is desirable for good energy-saving effects and reducing pollution. Compared with ordinary oil-immersed transformers, fully sealed transformers have eliminated the oil conservator. The oil volume of the transformer is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank.
