S11-M 20kV/0.4kV 30KVA-2500KVA Oil Immersed Transformer-Winding Series

S11-M full-sealed oil-immersed power transformer developed has the advantages of low loss, low noise and high efficiency and can achieve good energy-saving effect and reduce pollution. Compared with common oil-immersed transformer, it is unnecessary for full-sealed transformer to be equipped with oil conservator and change in oil volume is automatically adjusted and compensated by elasticity of corrugated sheet of corrugated tank, and transformer is isolated from air to prevent and slow down oil degrading and insulation aging, enhance operational reliability, with normal operation and no maintenance.
