b_201_152_16777215_00_images_stories_produkte_impraegnierung_wickelgueter.jpgImpregnation technique, Partial discharge, Avionics

Winding materials for special applications need to fulfill highest requirements. For such special purposes, we offer:

  • Extremely high working voltage on smallest space by Super Impregnation
  • Long-term durability by impregnation and special test processes, such as the Partial discharge measurement
  • Many years of experience
  • Highly automated production for constant quality

Increase your outstanding product portfolio with our long-term experience,  our manufacturing and impregnation technique.


A small overview of our products that are used in all usual aircraft types, i.e. Airbus A380 and Boing Dreamliner 777, are listed in the register Avionics.


Grouting techniquevergusstechnik.jpg

The Grouting gives products an advantage regarding

  • moisture proofing,
  • insulation, as well as
  • heat dissipation.

Currently we use this technique for household appliances for heat dissipation and for avionics.
