摘要：
One of the obvious motives for development of superconducting power transmission cables is reduction of transmission losses. Loss components in superconducting cables as well as in conventional cables have been examined. These losses are used for calculating the total energy lasses of conventional as well as superconducting cables when they are placed in the electric power transmission network. It is concluded that high load connections are necessary to obtain energy sating by the use of HTS cables. For selected high load connections energy saving of 40% is expected. It is shown that the thermal insulation and cooling machine efficiency are the most important loss element in a superconducting cable system.
