The invention discloses an extra-high voltage (EHV) fiber composite material skeleton overhead wire formed by a fiber reinforced composite material hollow skeleton and an outer conductor. The fiber reinforced composite material hollow skeleton has a supporting effect and the outer conductor has a conductive effect. The cross section of the fiber reinforced composite material hollow skeleton is in an annular shape and is divided into two layers, wherein an inner layer is unidirectional fiber enhancement and an outer layer is bidirectional fiber enhancement. The outer conductor is made of conductive metal such as silver, copper, aluminum and the like and has a cross section in a circular or profiled shape. The fiber reinforced composite material hollow skeleton in the annular shape may increase the diameter and the outer surface area of the wire so as to relieve a corona discharge phenomenon of the wire under the EHV condition. Used as the fiber reinforced composite material hollow skeleton, a fiber composite material is light in weight and good in mechanical properties so as to enable the wire to be light in weight, good in performance, and low in sag. The EHV fiber composite material skeleton overhead wire is suitable for being used in the EHV environment.
