Abstract
An apparatus in the field of power transmission, the apparatus includes a superconducting component or another component to be cooled, in a cryostat. A vacuum switch is provided in order to prevent heat being introduced into the cryostat by means of thermal conduction through the electricity cable of the component in the event of an electricity failure. This vacuum switch is integrated in a bushing in the electricity cable, so that its vacuum completes the thermal insulation of the cryostat.
