The at least one HTS-tape being at least partly surrounded by a cooling layer comprising said fluid cooling medium and an electrical insulation at least partly impregnated with said fluid medium. The power cable of the invention has shown to reduce the risk of fault current and electrically breakdown. When extra cooling is needed for stable operation the cooling medium may evaporate in the cooling layer for providing the cooling.
