Anti-rain protection system, in particular external anti-rain protection system for an electrical machine

摘要

Use of a rain protection system as part of a main insulation of an electrical machine, which includes flat particles, resistant to partial discharges and electrically conductive as fillers in a polymer matrix, to constitute paths for electrical current, characterized in that The filler further includes spherical particles resistant to partial discharges and electrically conductive, by means of which the electrical conductivity in the direction transverse to the electrical current paths of the flat particles is ensured.
