Abstract
Abstract An electrical superconductor comprises a hollow prismatic member consisting of a cylindrical tube covered with an extra layer of the slightly resistive material to form the external shape, and containing superconductor elements, and a lining of mechanically strong material, fixed onto the prismatic member.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
84 words
A stabilized superconducting cable comprising: a hollow member consisting Of material having very low resistivity at low temperature, a plurality of superconductor elements, in the form of wires or strips, which are embedded in the hollow member and distributed around the cavity thereof, and a base consisting of material having high-mechanical strength rigidly coupled to said hollow member, said base bearing against one of the faces of said hollow member and comprising two edges which are bent over and embedded in said hollow member.
Claim 2
Dependent Claim
