1. A method of mounting a support member in a rotating electric machine having a rotor, a stator, and stator windings, the windings including high voltage cable drawn through slots in the stator, wherein support members are arranged inside the slots along and in contact with the windings, said support members including a hose with a substantially triangular cross-section, the method comprising:
evacuating air inside a support member to shrink the support member;
pulling the evacuated support member with a wire extending through the support member into a slot; and
expanding the evacuated support member by releasing the vacuum inside the support member to make the support member clamp a cable inside a slot of the stator.
