Dielectric problems in the development of resistive cryogenic and Superconducting Cables

The intent of this paper is to review the electrical insulation concepts which are being considered for resistive cryogenic and superconducting cables and to call attention to our lack of understanding of many of the dielectric phenomena which will influence the design of future low-temperature cables. Since the author is more familiar with wrapped impregnated systems than with the other dielectric systems, this topic will be emphasized.
