Abstract

Selon la présente invention, une barre conductrice à n plans (n = 4, 6, 8 ... n - 2, n) est réalisée par n/2 - 1 pliages de la barre Roebel à 2 plans constituant la barre initiale fictive, de telle manière que la position en hauteur de chacun des axes de pliage est donnée par la relation m.(2h/n) (m = 1, 2, 3 ... m - 1, m), dans laquelle h est la hauteur de la barre. Application notamment aux enroulements d'entrefer des turbo-alternateurs de grande puissance, par exemple supraconducteurs.
