In order to adapt to the rapid development of ultra high voltage transmission line and improving the efficiency of power engineering of all kinds of maintenance work

in view of the angle of a tower grounding resistance line articulated difficult situation

this paper states a new ground wire structure which is an optimal solution by checking the docking ground parts. The demo of model has been tested by safey experiments in real working situation.It finds that the new style structure of ground wire can be used by hand in a long distance and lose weight sharply. The result of research shows that the weight of the new grounding wire is 54% lower than that of the bar grounding wire

while it not only apply to tensioning corner tower

but also is used to change the length and section of grounding wire according to the needs. It has high practical value in application of different tower shapes and different voltage levels.
