Abstract

This study examines cooling of superconducting power cables with counter-flow of liquid nitrogen with thermal contact through the cable dielectric. We investigate the effect of thermal conductance of the cable dielectric between coolant streams flowing in opposite directions, analyze longitudinal temperature distribution in superconducting power cables using heat balance equations, and give some examples taken from a cooling design study on superconducting power cables.
