FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, particularly a corona shielding paper, and can be used in a corona shielding system for an electric machine, for example a high-voltage machine. In the simplest case, the corona shielding paper is produced by compacting partial discharge-resistant, planar, conductive particles but can comprise both reinforcement fibres and a woven fabric. Disclosed paper comprises planar and electrically conductive coated particles, wherein spherical particles are additionally mixed for targeted control of anisotropic electrical conductivity to planar particles.
EFFECT: higher stability of the corona shielding paper.
