Amorphous alloy distribution transformer uses a new type of permeability magnetic material: amorphous alloy. The iron core is made up from amorphous alloy and in the structure of three phases and five columns. Amorphous alloy core is processed with annealing treatment. The iron yoke is staggeringly jointed. The iron core and winding coils both have rectangular cross sections.

These transformers are widely used in industrial engineering, agriculture and urban communities, especially in the power network of the countryside and developing areas.

Note 1: Transformers of “Yyn0” can also be supplied upon demands if the iron core is in the structure of three phases and three columns. Note 2: If the rated capacity is 500kV.A or below, the data of “On-Load Loss” on the left of slash (/) is suitable for Dyn11, on the right for Yyn0. Note 3: Transformers with other loss values can also be supplied upon demands. Note 4: Three-phase transformers with other high voltage tapping range can also be supplied upon demands.
