Oil immersed transformer - 10kV S13 / 20 / 22 series

 S13 type is developed and designed on the basis of S11 type. It fully absorbs the structural advantages of S11 type transformer. At the same time, the best Hi-B silicon steel sheet is used as the magnetic conducting material, and the lower magnetic flux density is selected to reduce the no-load loss of the transformer by 30% compared with S11 type.
