Grounding wire hook rail structure

The invention discloses a grounding wire hook rail structure. In order to solve the deficiencies of a traditional grounding wire hook rail structure that personal injury accidents are always caused and huge potential safety hazards exist when a downlead is damaged or a user carries out inverse power transmission, the grounding wire hook rail structure is characterized in that a power approaching alarm (2) is also arranged between a hanger (1) and an insulation hook rail (3), and the other end of the insulation hook rail (3) is connected with a telescopic hook (4). Therefore, the grounding wire hook rail structure has the advantages that the downlead is not required and the potential safety hazards caused by downlead damage or the inverse power transmission of the user can be eliminated.
