Amorphous Alloy oil immersed distribution transformer
1. Scope of application
Amorphous alloy oil immersed distribution transformer is using amorphous alloy material core and three-phase five-column structure. Its loss is particularly low that no-load loss is 75% lower than conventional type, and the annual operating cost is reduced by 22.7% that the energy-saving effect is very significant. It adopts fully sealed maintenance-free structure, which is safe and energy-saving. Transformers with rated capacity range from 30KVA to 2500KVA are suitable for AC 50Hz/60Hz, working voltage 6KV~38.5KV and below power system. They are used as substation equipment in power transmission and distribution fields, infrastructure fields, public transportation, buildings and residences, industrial fields, information technology fields and new energy fields.

4. Product advantages
1) Iron core: adopted 45° full inclined step joint process, which effectively reduces no-load loss, no-load current and core noise. The clamping and pulling plate structure makes the iron core stable and firm as a whole, thereby improving the resistance to short circuit and impact.
2) Coil: high voltage adopts cylindrical type, while low voltage adopts cylindrical type or foil type, which improves the resistance to short circuit. An oil guide structure is provided inside the winding to improve the oil flow path, thereby reducing temperature rise and increasing load capacity.
3) Oil tank: fully sealed bell structure, the reinforced iron of the oil tank adopts corrugated folding plate structure, less welds, high mechanical strength. The cooling device adopts a chip radiator, which has faster circulation speed, high heat dissipation efficiency and improved overload capacity.
4) Body: All insulating parts, winding outlets and lead welding parts have been rounded. The upper and lower parts of the device are positioned rigidly, which can ensure that the body does not shift under various transportation conditions.
5) Energy saving: No-load loss is reduced by about 75% comparing with conventional oil-immersed distribution transformers.
