SUPERCONDUCTIVE MULTIPHASE CABLE SYSTEM METHOD OF ITS MANUFACTURING AND APPLICATION Russian patent published in 2014 - IPC H01B12/16 

FIELD: electricity.

SUBSTANCE: invention is related to superconductive multiphase cable system of direct or alternating current for the purpose of electric energy distribution with fluid cooling, and the system contains a) a cable with at least three electrical wires being at least three phases and a zero or neutral wire, at that the above electrical wires are isolated from each other electrically and b) heat insulation setting the central longitudinal axis and having inner surface surrounding the cable, at that the above inner surface of the above heat insulation forms a radial limit for the cooling chamber intended for cooling of fluid used for cooling of the above electrical wires. The invention is also related to the method of the cable system manufacturing and its application.

EFFECT: according to invention in the cable system electrical wires contain superconductive material in the form of strips or wires twisted around the lower layer thus forming a superconductive layer and located in the order and under the unwinding angles which ensure low electric energy losses of alternating or transient current due to optimisation of a superconductive strips number and current distribution in the superconductive layers.
