Abstract
A method for mounting a tube in a space having a shape corresponding to the shape of the tube. The tube is inserted into the space, pressurized with a hot pressure medium causing the tube to expand until the space is filled, then a cold pressure medium is substituted for the hot pressure medium while maintaining constant pressure causing the tube to solidify in its expanded shape. Also, a rotating electric machine having such a tube between windings of a high-voltage cable in a stator slot.
