Abstract: The present invention is directed to a twisted conductor in which better use is made of the material and at the same time the structural dimensions are reduced. The partial conductor has a sharp bend so that the two partial conductor stacks are mutually parallel and leave a space between them. An intermediate piece is fitted in this space in the region of the bend. Thus there is a cooling channel in the twisted conductor for the radial flow of coolant. To ensure that the partial conductor bunch forms a coherent twisted conductor there is a casing in the region of the bend. This casing is a glass-cloth binding pre-impregnated with epoxy resin in the B state. Because of the improved filling factor, the structural height of the transformer can be reduced, resulting in the elimination of the paper insulation itself and the longitudinal intermediate pressboard layer. Moreover, the intermediate pieces can be thinner since there is no longer any need to allow for the expansion of the paper in the spacers.
