Amorphous Distribution Transformer

Description

This kind of transformer can take replace of silicon steel iron-core transformer and widely used in the outdoor distribution system. As the transformer adopt for the city and rural distribution network. It's iron-core is amorphous strip material, the no-load loss is *5% less than S9 transformer and the LV winding is copper winding, which would increase the short-circuit bearing ability. The vectory group is Dyn*1, 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 *5% 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 SBH**-M****0/*0 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.
