Roebel bar for an electric machine and manufacturing method of such a roebel bar

摘要

The bar (10) has a number of essentially parallel transposed sub-conductors (11-13) arranged above and/or next to each other to form a bar of essentially rectangular cross-section enveloped by insulation (19) with an internal discharge protection arrangement between the insulation and sub-conductors containing pre-formed angled profiles (17,18) of electrically conducting material in the longitudinal direction enclosing the edges of the rod. An independent claim is also included for the following: (a) a method of manufacturing an inventive device.
