摘要（英）：

The invention relates to a grounding device for reducing shock ground impedance of an electric transmission line tower, and belongs to the technical field of electrical grounding devices. The grounding device mainly comprises a guide conductor and shunt conductors. The grounding device has the characteristics that the grounding device is simple in structure, convenient to mount, high in grounding conductor utilization rate, and wide in the application area, and can reduce the shock ground impedance effectively; lightning protection levels of electric transmission lines are raised; and lightning stroke trip-out rates of the lines are reduced. The grounding device can be widely applied to the electric transmission line tower, in particular to the tower in a high soil resistivity area.
