Abstract

A holding arrangement is disclosed which can be employed to hold a winding enclosure which contains a low-temperature-cooled electric winding on which alternating external forces act, and which is fastened within a vacuum tank by means of tie rods. In particular, the arrangement includes pre-tensioned tie rods which are arranged to unilaterally pull, via pressure posts, with force-transmitting contact the winding enclosure against the inside walls of the vacuum tank. More specifically, the tensioning force at room temperature is selected such that at low termperature a residual tension force remains which is always at least as large as the component of the external force opposing it. With such a design for the holding arrangement no readjustment devices are necessary and the heat conduction effected thereby is relatively minor.
