The invention provides a bus brace and pantograph brace porcelain insulator on a roof of an electric locomotive. The insulator comprises an upper accessory, non-circular porcelain and a lower accessory. The non-circular porcelain is high-strength porcelain and is in a shape formed by arranging multilayer umbrellas, large umbrellas and small umbrellas in order at intervals, the cross sections of multilayer umbrella skirts and rod diameters of the non-circular porcelain are in non-circular streamline shapes, and a layer of homogenous self-cleaning glaze is applied to the surface of the non-circular porcelain. The upper accessory and the lower accessory are made of anti-corrosion high-strength metal materials and are in non-circular fit with the non-circular porcelain. When the bus brace and pantograph brace porcelain insulator on the roof of the electric locomotive run, a non-circular long shaft is installed in the locomotive traveling direction, a vortex negative pressure zone of the leeward surface of the insulator can be effectively eliminated through the arrangement, the dirt deposition phenomenon of pollutants in the leeward surface region of the insulator is reduced, and the phenomena of pollution flashover, wet flashover and ice flashover caused by the bus brace and pantograph brace porcelain insulator on the roof of the electric locomotive are avoided.
