• Amorphous Alloy Iron Cores

  Classification of Amorphous Cores/Lamination

  • Three-phase oil-immersed amorphous alloy distribution transformer core
  • Single-phase oil-immersed amorphous alloy distribution transformer core.
  • Three-phase dry type amorphous distribution transformer core.
  
  

  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.
