FEATURES
1)On the basis of S9 series, the no-load loss of S11-S13 series products is reduced by 30% on average, and the no-load current is reduced by 70%-85% compared with S9 series.
2)We improve the effectual support of the loop's terminal face to strengthen the anti-short circuit electricity capability.
3)The box is the corrugated radiator tank, not only has the cooling function but also has the 'breathing' function. The elasticity of the corrugated radiator can compensate the oil volume change caused by the temperature change.
4)The three-phase oil Immersed distribution transformer applies new type insulating structure and make the short-circuit resistance strong.
5)The Iron core is made of high quality cold rolled silicon steel plate.
6)High -voltage winding groups is made up of high quality oxygen free copper lines and it adopts multi drum type structure.
