A rotating electric machine (1) has a rotor, a sta- tor (2), and stator windings (3, 4). The windings (3, 4) include high voltage cable drawn through slots (5, 6) in the stator (2). Support members (8) are arranged inside the slots (5, 6) along and in contact with the windings (3, 4), said support members (8) comprising a hose (8') with a substantially triangular cross-section. A wire (9) is extending through and being attached to each support member (8). When mounting the support members (8) air in- side a support member (8) is evacuated in order to shrink the support member (8). Then the wire (9) extending through the support member (8) is used to pull the evacu- ated support member (8) into a slot (5, 6), whereupon the evacuated support member (8) is expanded by releasing the vacuum inside in order to make it clamp a cable inside a slot (5, 6) of the stator (2).
Une machine électrique tournante (1) est munie d'un rotor, d'un stator (2) et d'enroulements de stator (3, 4). Les enroulements (3, 4) comprennent un câble haute tension tiré à travers des fentes (5, 6) du stator (2). Des éléments de soutien (8) sont arrangés dans les fentes (5, 6) le long des enroulements et en contact avec ceux-ci (3, 4), lesdits éléments de soutien (8) comprenant un tuyau (8') doté d'une section transversale essentiellement triangulaire. Un fil (9) se prolonge dans chaque élément de soutien et y est fixé (8). Lors du montage des éléments de soutien (8), l'air à l'intérieur d'un élément de soutien (8) est évacué afin de le rétrécir. Ensuite, le fil (9) se prolongeant dans l'élément de soutien (8) est utilisé pour tirer l'élément de soutien évacué (8) dans une fente (5, 6), où l'élément de soutien évacué (8) est expansé en libérant le vide à l'intérieur de façon à lui faire serrer un câble à l'intérieur d'une fente (5, 6) du stator (2).
