ABSTRACT:
A rotating electric machine (1) has a rotor, a stator (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 inside 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 evacuated 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).
