Abstract
The special problems that arise when designing a superconducting system are examined. These are: (1) that the voltage and current levels chosen must permit economic integration into existing transmission and generation facilities; (2) the mechanical design of components that get cold must permit relatively large absolute contraction and possibly differential contraction without damage that may affect successful operation, and cool-down and warm-up cycles throughout the life of the system should not cause deterioration of the dielectric insulation; and (3) the dielectric losses of the insulation must be carefully controlled in AC systems. Basic research on cryogenic dielectrics is briefly reviewed, and 11 projects around the world that have engaged or are engaging in electrical insulation testing of prototype cables are described. The development of accessories is discussed.<>Keywords
