Abstract

Carcasse de transformateur présentant de hautes qualités d'isolement électrique. Elle comprend une carcasse intérieure comportant un mandrin, des joues, des embases et, autour du mandrin, contre les joues, deux feuillures sur lesquelles prennent appui, après bobinage du primaire, deux demi-carcasses extérieures s'emboîtant l'une dans l'autre par un assemblage à recouvrement. Ces demi-carcasses sont destinées à recevoir l'enroulement secondaire. Application aux transformateurs d'équipements d'abonnés pour centraux téléphoniques.
