Beschreibung
Zusammenfassung:	A multisection superconducting cable for carrying alternating current is provided which comprises a heat insulation envelope, a superconductive shield with a stabilizing substrate and an electrical portion for carrying an electrical current and including at least one conductor assembly of two coaxial cores. One of the cores is made tubular and provided with a superconductive layer and a stabilizing substrate. The other core extends inside the tubular core. The stabilizing substrate of each section of the electrical portion and of the shield are formed by local segments of a stabilizing material. The segments are separated by a material of a lower electrical conductivity than the stabilizing material, the resistance of the stabilizing substrates within each section being in excess of the impedance of the electrical portion of this section. Both the cores of the electrical portion are electrically connected at least in the points intended to be used for connection of terminal devices. The inner core is made of a normal metal and the thickness of the stabilizing material of the substrate is not in excess of the effective depth of penetration of alternating current. The proposed cable can find its practical utilization in superconducting transmission systems.
