IEC 63075:2019 specifies test methods and requirements for high-temperature superconducting (HTS) AC power cable systems, cables and their accessories, for fixed installations, for rated voltages from 6 kV ( U<\/em> m<\/sub> = 7,2 kV) up to and including 500 kV ( U<\/em> m<\/sub> = 550 kV). The requirements apply to single-core, three-core and three-phase concentric cables with cold dielectric and their accessories that are not intended for fault current limitation purposes. This document does not cover special cables and their accessories, such as fault current limiting cables or submarine cables, for which modifications to the standard tests may be necessary or special test conditions may need to be devised. This document does not cover test methods and requirements for the cooling system.<\/p>\n
