The invention discloses a prestressed concrete transverse web member type strut for an electrified railway contact network. The prestressed concrete transverse web member type strut comprises ultra-high performance concrete and a plurality of arch frames, the plurality of arch frames are poured in the ultra-high performance concrete from bottom to top; each arch frame comprises two groups of arch-shaped structures; each arch-shaped structure comprises an annular frame and two V-shaped frames; the two V-shaped frames are fixed to the two ends of the annular frame respectively, the two V-shapedframes are symmetrical about the center of the annular frame, the two sets of arch-shaped structures are arranged in parallel and fixedly connected through a plurality of vertical short ribs, and thecentral axes of the annular frame bodies of the two sets of arch-shaped structures are located on the same vertical line. The overall strength and rigidity of the transverse web member type strut areimproved, stress distributi
