SUPERCONDUCTING WIRE OF "SHEATHED CABLE" TYPE (CONDUIT CABLE) Russian patent published in 2011 - IPC H01B12/16 

FIELD: electricity.

SUBSTANCE: superconducting wire of "sheathed cable" type (conduit cable) for windings of magnetic systems, including windings of thermonuclear fusion plant of TOKAMAK type, and windings of energy accumulators "SPIN". Wire comprises superconducting core and metal sheath. Channels for coolant pumping are provided between inner surface of sheath and outer surface of superconducting core. Sheath may be arranged as combined with inner part in the form of all-metal seamless pipe of aluminium or its alloys, and external part is made of steel or titanium. Channels to pump coolant between superconducting cores and shell may be formed by making inner surface of aluminium pipe as shaped with ribs or ledges. Channels may be formed by arrangement of gasket in the form of spiral wound onto core between superconducting core and sheath.

EFFECT: invention makes it possible to develop absolutely tight system of coolant circulation with provision of increased density of flow due to selection of optimal ratio of areas of cross section of channels and area of wire and coefficient of fill with superconductor.
