Nanocrystalline Cores for Power Transformer (LLE-PC)

Naocrystalline Cores for Power Transformer(LLE-PC)

1.Features:
  • High permeability 
  • High saturation Induction ,Low core loss
  • The density and lamination coefficient of nano-crystalline is lower than that of                                                        
  • Permalloy, under the condition of the same size and similar performance of the
  • two. It is 1/4 lighter in weight, and 1/3 lower in the manufacturing cost.
  • Good temperature stability:work for a long time at temperature of -55 ~ 130 ℃
  • The linear range of nano-crystalline alloy is wider than that of Permalloy .
