40KVA 3 phase autotransformer advantages:

Choosing a three phase transformer manufactured and supplied by Shuogong Power has the following advantages:

  • Made of high quality silicon steel sheet.
  • Optional copper wire or aluminum wire.
  • Available with or without housing.
  • Configure the scroll wheel.
  • Fast delivery.
  • 100% quality assurance.
  • Sufficient power never cut corners.

3 phase autotransformer advantages.

  • three phase autotransformer consumes less materials and has low cost. The amount of silicon steel sheet and copper wire used in transformer is related to the rated induced potential and rated current of the winding (that is, it is related to the capacity of winding). The winding capacity of 3-phase autotransformer is reduced, the material consumed is also reduced, and the cost is reduced, so the price is lower.
  • three phase autotransformer has low loss and high efficiency. Due to the reduction in the amount of copper wire and silicon steel sheet, under the same current density and magnetic flux density, the copper loss and iron loss of a 3-phase autotransformer are less than that of the dual-winding transformer, so the benefit is higher.
  • three phase autotransformer is easy to transport and install. 3-phase autotransformer is lighter in weight, smaller in size and smaller in footprint than the dual-winding transformer of the same capacity.
  • three phase autotransformer improves the ultimate manufacturing capacity of the transformer. The ultimate manufacturing capacity of transformers is generally limited by transportation conditions. Under the same transportation conditions, the manufacturing capacity of an autotransformer is larger than that of the double-winding transformer.
