The quality of production and repair of electrical machines is very much determined by the quality of electrical insulation.
SIBEL Ltd. offers the high-quality insulation materials of the world leader in electrical insulation – the concern VON ROLL – Switzerland.
The RESIN RICH system is the most widely used for the production and repair of HV motor sections. The electric insulating material used contains a relatively high percentage (about 40%) of thermosetting resin, which is simultaneously pressed and baked in special presses. It does not need to be further impregnated with resin.
The main advantages of the RESIN RICH insulation system are the following:

  • Use of modern insulation materials.
  • Automatic placement of insulation.
  • Thermal insulation class – class F.
  • High insulation breakdown voltage – over 50 KV/mm.
  • Low water absorption of the system – practically absent.
  • Small dielectric losses.
  • Low cost of repairs.
  • Not very complex process and equipment.
  • Mica based insulation for high partial discharge resistance.

Main advantage is repairability, i.e. any damaged section can be removed from the stator side and a new one can be r eplaced, with minimum cost of repair.

  Modern insulation materials that fulfill the specific requirements applicable to the RESIN RICH system:
