Abstract
L'invention concerne des bobinages pour machines électriques obtenus en enroulant un materiau isolant composite autour d'un conducteur électrique, ledit matériau isolant composite ayant été préparé en liant deux ou plusieurs matériaux isolants à l'aide d'une résine de silicone dont la structure moléculaire comprend des groupements hydroxy, en imprégnant ledit matériau isolant composite avec un vernis isolant comprenant 1 équivalent de composé époxy polyfonctionnel et 2,5 à 25 équivalents d'un isocyanate polyfonctionnel et en durcissant ledit vernis. Les bobinages obtenus ont d'excellentes propriétés d'isolation dans des conditions de température et d'humidité élevées et ont une résistance thermique de la catégorie H ou plus.
