Nanocrystalline based on nanocrystals less then 10 nanometer in their physical structure, therefore cores made by nanocrystalline are much more superior then the other soft magnetic material.

Suitable Application:
  • Current transformers: With 0.2; 0.2s; 0.1 accuracy class. Bushing current transformer for gas insulated or oil-immersed switchgears. Lv, Mv & Hv switchgear, and other apparatus in electric power transmission.
  • Power transformers: Switch mode; pulse; inverting; square wave, isolation.
  • Current sensors
  • Frequency converters
  • Smps
  • Ac inductors
  • Dc inductors
Characteristics:
  • High permeability
  • Minimized current measuring error in CT
  • High saturation induction
  • Small size and light weight compared to Nickel alloy CT
  • Excellent thermal stability can work at -55 °C - 155 °C for long time
  • Low cost
  • Light weight and minimize the core dimension compared with Nickel Alloy.
  • Good linearity
  • Protected with plastic case & psp boxes also aluminum boxes
  • Wide range of permeabilities
