Abstract

1. A choke for large electric outputs having windings (1) round core flanks made of axially aligned and spaced iron core discs (2) and with yokes (3) which are arranged at the ends above and below the windings and which are fixed by metallic tension elements (4) which coaxially penetrate the iron core discs (2), where said tension elements (4) are made of a high-tensile steel and exclusively dimensioned by taking into consideration the mechanical stress, characterised in that, in the region of the iron core discs (2) and the yokes (3), the tension elements (4) are surrounded by a sealed casing (6) consisting of a material of high electrical conductivity, e. g. of copper or aluminium, which is contrived to be such that the eddy currents produced in the casing (6) reduce the magnetic field inside the tension elements (4) in relation to the magnetic field, which is to be expected without a casing, to a partial amount which is just sufficient in order to maintain the eddy currents in the casing (6) and that the tension element (4) has a rectangular cross-section and the longer sides of the cross-section are arranged to be parallel to the layer direction of the sheets in the yoke (3).
