ABSTRACT:
A high-voltage system has an insulation-gas filled metallic encapsulation which surrounds active parts to which voltage is applied. A first protective coating (3) is provided on the internal surface of the encapsulation, as it is on the external surface of the active parts. As a result, a high-voltage system is provided in which a reduction of the dielectric strength of the insulating gas paths cannot occur as a result of freely mobile particles (5). This is achieved by covering the first protective coating (3) at least partially with a second protective coating (4).
