Abstract

This chapter describes the benefits and associated technical challenges of closed-loop cryogenic helium gas circulation for cooling high-temperature superconducting cable systems. The many potential applications of gaseous helium-cooled high-temperature superconducting cables are discussed. The major technical challenges specific to the development of gaseous helium-cooled superconducting power cables are also described. The need for the development of new cryogenic dielectric material systems for realizing medium-voltage power cables is emphasized. Available technology for ...
