In apparatus for supplying power to electrical devices having conductors cooled to a low temperature and in which the apparatus establishes connections between normal conductors at room temperature and the cooled conductors, with the end of the cooled conductors which are connected to the normal conductors located in the gas flow of an evaporated coolant, means are provided to supply an additional cold gas into the gas flow of the evaporated coolant at a temperature level which is above the evaporation temperature of the coolant thereby permitting the conducting cross-sectional areas of the normal conductors in the apparatus to be designed only for an average operating current and to thereby reduce coolant losses.
