It is suitable for distribution system with 10KV, 50Hz for industrial and mine enterprise and power illumination.
It conforms to GB1094 (power transformer standard)
It is a new generation of energy saving product. Its strong points: Advanced workmanship, advanced performance technology, novel design, nice appearance and less ground demand.
1. Iron core is made of plate and seamless, ungraded. Its section closes to pure circle. Iron yoke and core limb link as rounded corner. The iron core is sealed.
2. High & Low voltage coil around iron core directly. Two coils have good concerntricity and strong anti-short circuit.

3. Because of its special structure of the iron core, coiling and burning crystalline state orientation high-quality cold-rolled silicon sheet, comparing to same capacity S9 type, S11-M. R no load loss falls by 30%, no load current falls by 70%, and noise reduce by about 8dB.
4. Instead of oil conservator, we use ripple typing tank. Oil volume variations caused by temperature are adjusted by turbo wave flexibility to isolate from air and prolong service life.
