The utility model discloses a heat shield for hot-line work of a heat-resisting guide line. The heat shield for the hot-line work of the heat-resisting guide line comprises a heat shield main body (1) and a pair of U-shaped hooks (2), wherein the section of the heat shield main body is U-shaped, the pair of U-shaped hooks (2) are arranged on the inner wall of the heat shield main body (1), and an insulated handle (4) is arranged at the lower end of the hook (2). The heat shield for hot-line work of heat-resisting guide line has the advantages of conducting heat insulation protection to operating personnel in the process of the hot-line work of an electric transmission line of the heat-resisting guide line, preventing the operating personnel from being influenced by high temperature, keeping the points between the operating personnel and the high-temperature guided line equal and the potential difference between during the hot-line work zero, and doing no harm to a human body and being simple in structure and good in safety performance.
