An electricity supply system for traction comprises at least one transformer, for example an autotransformer or current booster transformer, and/or a rotating convertor. The transformer or rotating convertor comprises a winding including insulation consisting of at least two semiconducting layers (32, 34), each providing a substantially equipotential surface, and solid insulation (33) between the semiconducting layers.
On décrit un système d'approvisionnement en électricité d'un moteur de traction comprenant au moins un transformateur (auto-transformateur ou transformateur survolteur, et /ou convertisseur tournant, par exemple). Le transformateur ou convertisseur tournant présente un enroulement muni d'un isolant constitué d'au moins deux couches semi-conductrices (32, 34) comportant chacune une surface sensiblement équipotentielle, et d'un isolant solide (33) intercalé entre les couches semi-conductrices.
