Abstract

L'invention concerne un appareil électrique inductif comportant un enroulement électrique 10, 12 isolé électriquement dans une enceinte, un fluide diélectrique isolant entourant l'enroulement 10, 12, et une structure isolante 16, 18, 22 comportant des pièces 16, 18 associées avec l'enroulement et qui se projettent dans le fluide diélectrique isolant. Chaque pièce isolante 16, 18 comporte un liant adhésif solide et une charge de microsphères, tandis que le liant et les microsphères sont choisis de telle sorte que ces microsphères constituent entre 25 % et 75 % en poids de la pièce isolante 16, 18 pour que, de façon optimale, la structure isolante 16, 18, 22 ait une constante diélectrique basse aussi proche que possible de la constante diélectrique du fluide diélectrique isolant. Application aux transformateurs de puissance.
