Abstract

The invention discloses a 110 kV double-loop drilling tower and relates to the field of electric power pole towers. The 110 kV double-loop drilling tower comprises a tower body, and the tower body comprises a tower body main material, tower body cross inclined materials, tower legs and leg inclined materials connected with the tower legs; cross arm structures, namely a ground wire cross arm and aconducting wire cross arm, are arranged on the tower body sequentially from top to bottom; the ground wire cross arm and the conducting wire cross arm are both symmetrically arranged on the two sidesof the tower body; and the whole drilling tower is made of angle steel. The 110 kV double-loop drilling tower comprises the double layers of cross arm structures, namely the ground wire cross arm andthe conducting wire cross beam, and the total height of the pole tower can be decreased. The whole drilling tower is made of the angle steel, the structure is simple, machining and manufacturing are convenient, the rigidity of the pole tower can be ensured, and safety is ensured. According to the 110 kV double-loop drilling tower, the height of the head of the iron tower is greatly decreased, andthus the total height of the iron tower is decreased. By using the 110 kV double-loop drilling tower, the width of a corridor can be decreased, the construction cost is lowered, and environmental friendliness of engineering is improved.

Description

technical field [0001] The present application relates to the technical field of power poles and towers, in particular to a 110kV double-circuit drill-through tower. Background technique [0002] As the power grid construction becomes more and more dense, 110kV transmission line projects often have the situation of drilling through other towers, and the drilling tower needs to maintain a sufficient clearance distance and ground distance for crossing. Therefore, the drilling tower needs to be reasonably designed , to ensure the security of the transmission grid. [0003] At present, many 110kV double-circuit drill-through towers on the same tower are usually equipped with three-layer cross arms, which are ground wire cross arms, upper wire cross arms, and middle and lower wire cross arms from top to bottom. The three-story cross arm is arranged vertically, the tower head of the pole tower is high, the construction is difficult, the construction volume is large, and it increa...
