Oil-immersed Power Transformer

Our oil-immersed power transformer has the advantages of low loss, low noise, etc., which can achieve good energy-saving effects and reduce pollution. Compared with ordinary oil-immersed transformers, the fully sealed transformer eliminates the oil storage cabinet. 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, enhancing operational reliability, and normal operation is maintenance-free.
