AMORPHOUS ALLOY IRON CORES

    Classification of amorphous alloy iron cores
  • Three-phase oil-immersed amorphous alloy distribution transformer core Single-phase oil-immersed amorphous alloy distribution transformer core
  • Three coherence is the core of amorphous alloy distribution transformer
    Product Characteristic
  • Small lightweight transformer to reduce direct material cost
  • The equipment is simple and fast, and the production capacity is greatly improved.
  • Low noise effect
  • Compared with the silicon steel sheet transformer of the same capacity voltage grade, the no-load loss is reduced by 70% and the no-load current is reduced by about 75%. The energy saving effect is obvious.
