Magnetic properties of combined magnetic cores

Combined magnetic cores GM 29-4 are made from electrical steel and nanocrystalline alloy GM 414. The insertion of nanocrystalline alloy GM 414 increases magnetic permeability in weak magnetic field.

Combine magnetic core GM 29-4:

  1. Magnetic core from electrical steel,
  2. Magnetic core from nanocrystalline alloy GM 414,
  3. Protective box.

Magnetic permeability of combine magnetic core GM 29-4 and components.

Combine magnetic cores are used in high-accuracy current transformers at frequency 50 Hz. The dimensions of combine cores are from minimal internal diameter 20 mm up to maximal outside diameter 600 mm.
