Ultrahigh-voltage cable and auxiliary equipment for production thereof

The invention provides an ultrahigh-voltage cable and auxiliary equipment for production thereof. The ultrahigh-voltage cable comprises a multi-layer structure arranged from inside to outside, the innermost layer is a conductor, the conductor comprises a plurality of solid strips, the cross section of each solid strip is of a fan-shaped structure, the plurality of solid strips can enclose to form a cylindrical structure, and the circle centers of the plurality of solid strips are located on the same straight line. The flexibility and the bending performance of the cable with the structure are improved; the auxiliary equipment for ultrahigh-voltage cable production comprises a mounting base, a supporting rod, a track plate and two limiting structures, one end of the supporting rod is fixed to the mounting base, the other end of the supporting rod is rotationally connected with the track plate, and the track plate is provided with a first track structure and a second track structure; one limiting structure is i
