Oil Immersed Power Transformer (S9/S11/S13 type)

1.FEATURES
S11-M.RL three-dimensional roll-core transformer series, the whole body is athree-dimensional triangular shape. And there are taut rods all around and in the central. With top and bottom frames, insulation, laminated wood, it is constituted as awhole body. The high and low voltage coils are circular and concentric winding, which can effectively resist the axial mechanical stress of sudden short circuit.
It has good anti-short circuit ability.
Compared the S11 -M.RL three-dimensional roll-core transformer series with ordinary transformers, no-load current is reduced by 75% and no-load loss is reduced by 30% in average. And the comprehensive energy saving is up to 15% -30%
