Abstract
A method for cooling a plant for superconductive cables is provided, where the plant includes two thermally insulated end closures () and at least one thermally insulated, tubular cryostat () arranged between the end closures, in which at least one superconductive cable is arranged. Liquid nitrogen contained in a cooling agent supply is pumped by means of a pump () through a first end closure and the cryostat to a second end closure. At least one vacuum insulated tank () is used for the cooling agent supply, where the tank () contains nitrogen at operating temperature and out of which the nitrogen is pumped. For making available a quantity of liquid nitrogen necessary for operating the plant, the supply of liquid nitrogen contained in the tank () is supplemented during operation or is switched over to another tank () containing liquid nitrogen.
