Electric transmission pole tower adopting novel crisscross-shaped grounding method

An electric transmission pole tower adopting a novel crisscross-shaped grounding method relates to the technical field of high-voltage electric transmission lines. The electric transmission pole tower comprises a pole tower main body and a grounding device, wherein the bottom of the pole tower main body is connected with the grounding device through conductors; the grounding device is composed of a horizontal grounding body and vertical grounding bodies; the horizontal grounding body is composed of an outer frame and a cross-shaped frame, the outer frame is sleeved out of foundation main columns, four end points of the cross-shaped frame are respectively welded with middle points of four edges of the outer frame, the outer frame and the cross-shaped frame are combined to form a crisscross shape, and the vertical grounding bodies are respectively welded at the middle points of the four edges of the outer frame and at the centre point of the cross-shaped frame. Angle steel is respectively welded at the middle points of the four edges of the outer frame and at the centre point of the cross-shaped frame, so that the grounding resistance is greatly reduced. The electric transmission pole tower adopting the novel crisscross-shaped grounding method, provided by the utility model, has the advantages of avoidance of digging of grounding troughs, reduced land clearing fees, lowered difficulty in coordination of civil matters, reduced vegetation destruction and construction cost, and protection of the environment.
