Abstract
A cooled multiphase ac cable comprising a means for protecting the cable against the effect of the axial magnetic flux, made of a superconducting material in the form of a plurality of closed conductors separately embracing the surfaces of the internal and external layers of stabilized superconducting material of the cable phases. The closed conductors embracing the surface of the external layer of stabilized superconducting material are electrically associated. The proposed multiphase cable is simple in manufacture, reliable in service and adequately protected against the effect of the axial magnetic flux.
