A high voltage rotating machine and an electric installation provided therewith

摘要

A high voltage rotating machine comprising
a stator part (1) equipped with: a core part (2); a winding comprising a plurality of coils (4) each of which comprises a plurality of parallel conductors (7), arranged in a predetermined order and covered by a surrounding electrical insulation (9); said coils (4) extending through said core part in slots (3) therein and protruding out of the core part (2), thereby defining an overhang part (6) outside the core part (2), wherein there is also provided a corona protection layer (10) covering at least one of said coils (4) in the region in which said coil (4) exits the core part (2). The corona protection layer (10) extends such that it covers said coil (4) throughout the whole length of the overhang part (6).
