The invention relates to electromechanical constructions. The stator for high-voltage electrical machine comprises three phase windings 1 in the form of spiral coils, placed between two insulating cylinders 2, 3 and separated by insulating layers 4, and is characterised in that each phase winding 1 is furnished with an electrostatic screen 5 bored with holes for the cooling agent, this screen encompassing the cross section of the winding 1 over its entire perimeter and being connected electrically to the neutral of the winding 1. The invention can be used most advantageously in high-power cryogenic turbogenerators. L'INVENTION SE RAPPORTE AUX CONSTRUCTIONS ELECTROMECANIQUES.LE STATOR POUR MACHINE ELECTRIQUE A HAUTE TENSION COMPORTE TROIS ENROULEMENTS DE PHASES 1 SOUS FORME DE BOBINES EN SPIRALE, PLACES ENTRE DEUX CYLINDRES ISOLANTS 2, 3 ET SEPARES PAR DES COUCHES ISOLANTES 4, ET EST CARACTERISE EN CE QUE CHAQUE ENROULEMENT DE PHASE 1 EST DOTE D'UN ECRAN ELECTROSTATIQUE 5 PERCE DE TROUS POUR L'AGENT DE REFROIDISSEMENT, CET ECRAN EMBRASSANT LA SECTION TRANSVERSALE DE L'ENROULEMENT 1 SUIVANT TOUT SON PERIMETRE ET ETANT RACCORDE ELECTRIQUEMENT AU NEUTRE DE L'ENROULEMENT 1.L'INVENTION PEUT ETRE UTILISEE LE PLUS AVANTAGEUSEMENT DANS LES TURBOGENERATEURS CRYOGENIQUES DE GRANDE PUISSANCE.
