1. Principle & Characteristics  

     S9 S10 S11 series oil-immersed full sealed distribution transformers are widely used for power supply & distribution in industrial and civil occasions, to step down grid voltage (11, 10.5, 10, 6.3, 6KV) to line voltage 400V, which can serve both indoors and outdoors at an ambient temperature range -25℃ to 40℃. With reasonable structure design, the transformers are qualified to withstand short-circuit and overload, and are free of maintenance and easy to repair. 
    The transformers have S9, s10,advanced S11 and the newest S13 series, the S11 is more recommended for the balance in less loss and reasonable price.
