The invention discloses a 10 kV pole-mounted switch protection cover. The 10 kV pole-mounted switch protection cover comprises a cover body and a cover head which are connected. A through hole through which the cover body and the cover head are communicated is formed in the protection cover. An opening communicated with the through hole is formed in the wall body of the protection cover in the axial direction of the through hole. A first connection piece and a second connection piece which extend towards the outer side of the protection cover are arranged on two edges of the opening respectively. The extending width of the first connection piece is larger than the extending width of the second connection piece. The side faces, connected in a butt joint mode, of the first connection piece and the second connection piece are attached to each other. Installation lugs for installation tools to be conveniently connected in a clamping mode are arranged on the outer wall of the protection cover. The wall body of the protection cover is made of elastic insulating materials. By means of the 10 kV pole-mounted switch protection cover, electrified installation can be rapidly and conveniently conducted, the electrified installation operation of the pole-mounted switch protection cover is greatly simplified, the labor intensity of installation personnel is lowered, and the work safety is improved.
