Abstract

The individual conductors of a cyrogenic cable are supported in the innermost tube of the cable assembly, having plural concentric corrugated tubes for establishing a controlled temperature gradient, in that short tube sections with peripheral longitudinal grooves are linked together, leaving a gap between each two sections, and in a chain-like configuration; the conductors are preferably wrapped helically around this carrier assembly.

A second chain of cylindrical bodies, on top of which is a conductor in the form of helically placed conductive elements of superconducting material, cylindrical bodies are formed with longitudinal grooves on the outer surface, and metal brackets are used as connecting elements. The invention is illustrated in cherries (Figs. 1, 2 and 3), where I are molded bodies with longitudinal grooves, 2; 3 - coupling brackets and 4 - superconducting material conductive elements. When the cable is bent or in the process of temperature expansions or contractions, the phymaligned pilissic bodies 1 are displaced relative to each other, with a brace 3, which limits this movement within the required limits. At this time, the diameter of the support element is kept constant and the conductive element 4 does not experience destructive loads. Due to the presence of longitudinal grooves, the refrigerant passes freely between the outer surface of the supporting element t and the inner surface of the conductor, which leads to an intensive cooling of the latter. The invention is an electric low-temperature cable containing concentrically arranged corrugated metal pipes and a central core consisting of connected via connecting elements in a multi-link chain of cylindrical bodies, over which the conductor is arranged in the form of spiral-shaped conductive elements made of superconducting material, characterized by that, in order to increase gi: boki and mechanical stability, cylindrical bodies are made molded with longitudinal grooves on the outer surface, and metal brackets were used as connecting elements.
