Abstract
A cable such as used in cryogenic and superconductive applications includes an inner conductor, an outer conductor or shield, and a solid dielectric between the inner and outer conductors. The dielectric is introduced into the space between conductors in liquid or gaseous form, preferably under pressure, and the temperature of the dielectric is lowered to or below the freezing point for the material. Pressure relief should the solid dielectric suddenly vaporize by rapid heat rise is provided by holes in the outer conductor or by scoring the inner surface of the outer conductor to provide rupture points in the conductor.
