【Abstract】 The high temperature superconducting (HTS) cables are most likely to be used for commercial operation in the urban underground transmission systems. They are aimed mainly at retrofitting of the city electric network to replace the traditional cable with HTS cable to increase its transmitting capacity without having to change the existing duct and transmission of huge electric power (larger than 1GVA) into the load center of large cities by means of 220kV HTS cable with transmission capacity of 1～4GVA instead of traditional 500kV power cable, and even by 110kV HTS cable to transmit some 1GVA electric power penetrating cities, which have been verified by the results of design of series HTS cables of different diameters of conductor formers and with rated voltages of 35kV, 110kV and 220kV respectively used for urban underground transmission systems. A criterion for determining the suitability of HTS cables for practical use is specified in the paper which is well justified.更多还原
