Abstract
Abstract A coolable cable such as a cooled superconductive cable or the like has one or more electric conductors and includes a conduit concentric therewith for directing a coolant therealong. A plurality of tubes are provided in parallel spaced relation to the electric conductor and a metal band is wound around the tubes and forms a radiation shield. Supporting members are disposed intermediate the conductor and the tubes at respective positions along the longitudinal cable axis for supporting the tubes and the metal band.
