Abstract

L'invention a pour objet de créer une machine électrique destinée à des tensions admises maximales de 6,6 kV, dont l'enroulement soit plus facile à fabriquer qu'une bobine formée à fils plats et qui empêche les effets négatifs sur le comportement de fonctionnement des machines haute tension. Pour ce faire, on utilise selon l'invention un enroulement à fils ronds semés par l'entaille (1) en version fil émaillé ou dénudé. Un ruban micacé est entouré, avec chevauchement, sur le fil et les chignons. Chaque enroulement, respectivement situé dans deux rainures (2) à moitié ouvertes, est composé d'au moins deux enroulements partiels (4 et 6) superposés, montés en série et isolés l'un de l'autre par des couches intermédiaires (5). Le revêtement de rainure (3) et l'isolement en phase sont assurés par une matière isolante de surface micacée.
