Abstract
Abstract In a current feeding device for conductors which are cooled to a low temperature, the conductors being connected to a cooled normal conductor which consists of metal netting, metal net with constant conductor cross section over its entire axial length is employed and has connected thereto in an electrically conducting manner a predetermined number of conductor elements of predetermined conductor cross section permitting simple metal netting with a large heat exchange area to be used for the normal conductors while allowing the conductor cross section of the normal conductor to be optimized with respect to minimum heat loss.
