S11-M 630KVA 10/0.4KV power transformer oil immersed power transformer
S11 full-sealed oil-immersed power transformer developed by the company 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.
