In order to adapt to the rapid development and meet the needs of maintenance of ultra-high voltage transmission lines,and to solve the problem of angle connection difficulty in transmission tensioning tower,a kind of hand-thrown grounding wire is designed according to the actual work in the field.Compared with the disadvantages of the two traditional grounding tools,a new type of grounding wire clamp structure is put forward.Through mechanical design and connection,it is the first time in the field of grounding wire clamp to realize the completion of the long-distance throwing and dismantling of the grounding wire with the single-direction force and double-section control wire clamp.Through the field 1∶1 transmission tower throwing and dismantling experiment,the connection is successfully completed,and it has been mass-produced after passing the safety test.According to the needs of power production,with the adoption of the mechanical wire clamp structure idea mentioned above,the corresponding wire clamp size is changed and the grounding copper wire of different lengths and sections is configured,which can be applied to the grounding of transmission lines of a variety of voltage levels.
