Abstract

L'invention concerne un noyau de transformateur comprenant au moins une branche et un élément culasse, la section de la branche ou des branches étant pourvue d'au moins quatre bords multiples réguliers. Le noyau constitué d'anneaux de bandes de largeur constante enroulées possède de bonnes propriétés électriques. Ce transformateur est également facile à fabriquer et réduit les déchets des matériaux.
