Amorphous Distribution Transformer

As the transformer adopt for the city and rural distribution network. It's iron-core is amorphous strip material, the no-load loss is 75% less than S9 transformer and the LV winding is copper winding, which would increase the short-circuit bearing ability. The vectory group is Dyn11, which would reduce the effect to the harmonic wave and improve the power supply quality. Before shipment every transformer have done full-wave lightning impulse test at a voltage 25% higher than national standard to insure the transformer in motion safely.As amorphous Distribution transformer can't bear mechanical force, and rectangle winding's mechanical intensity is week, it is a big difficulty for amorphous distribution transformer pass the short-circuit test, our company has captured this difficulty, exploited SBH16-M-2500/10 distribution transformer, it has passed the short-circuit test in ShenYang National Transformer Quality Supervision Testing Center. It demonstrates that our company's amorphous distribution design has came to the international advanced level.Functional characteristics Vecor Group: Dyn11 Impedance Voltage (%): 4%, 4.5%, 5% Rated voltage: H.
