Definitions

  • the object of the invention is to present a component with a metallized on its surface ceramic body, which is not exclusively plate-shaped, flat, and has a high partial discharge resistance.
  • the object is achieved by means of the characterizing features of claim 1.
  • Advantageous embodiments of the invention are presented in the dependent claims.
  • the component according to the invention is spatially structured.
  • the ceramic body is a three-dimensional structure.
  • connect to a plate more parts so that a body arises in any form.
  • the whole body is in one piece, d. h., he is not composed of individual parts.
