Abstract
To provide a cooling method of a superconducting cable line wherein moistures contained in the cable in the superconducting cable line after laid is removed before cooling, so that solidification of the moistures can be prevented from clogging of piping including a coolant flow channel and a return pipe. There is provided an inert gas generating vessel so that before the coolant is flown into the superconducting cable line, the inert gas is blown into the cable line from an inflow pipeconnected with a supply pipe' and is discharged from a discharge pipetogether with the gas. The inert gas is preheated by a heaterbefore feeding it into the cable line. The discharge pipeconnected with a discharge side B of the return pipeis provided with a moisture measuring instrumentto measure a moisture content of the discharged gas.
