Ring belt cores

We supply toroidal strip cores made of grain-orientated silicon steel in thicknesses of 0.10 – 0.30 mm. The toroidal strip cores are available in the following versions:

normal: For use with protective caps.

Reinforced with synthetic resin: To protect against the mechanical loads exerted by the copper winding.

coated with epoxy resin: Suitable for direct winding without further protection,

  • temperature-resistant up to 140 °C,
  • dielectric strength of 40-50 kV/mm
  • Thickness 250 µm.

In order to fulfil the magnetic requirements, we recommend the following ratio as far as possible
