SUPERCONDUCTING MULTI-PHASE CABLE SYSTEM, METHOD OF ITS MANUFACTURE AND ITS APPLICATION Russian patent published in 2010 - IPC H01B12/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to superconducting multi-phase cable system with cooling by fluid medium. Said medium comprises the following components, i.e. cable with at least three electric conductors making, at least two phases and zero or neutral wire. Note that said conductors are electrically isolated. It includes also heat insulation that sets central lengthwise axis and has inner and outer surfaces. Said inner surface of heat insulation forms radial limit of cooling chamber designed to hold conductors cooling fluid medium. Invention relates also to method of producing cable system and to its application. At least a section of said cable is arranged off-center relative to said central lengthwise axis and adapted to cable thermal shrinkage and expansion relative to thermal insulation.

EFFECT: higher reliability, reduced repair terms.
