Power transmission tower

The utility model discloses a power transmission tower. The power transmission tower comprises a tower body; a composite cross arm; the tower body and the composite cross arm are connected through the connecting rotating assembly, the composite cross arm can rotate relative to the tower body, the rotating axis of the composite cross arm rotating relative to the tower body intersects with the central axis of the tower body, and the included angle between the rotating axis and the central axis is an acute angle. According to the power transmission tower, the probability that the composite cross arm collides with the tower body under the abnormal operation working condition can be reduced. 本申请公开了一种输电塔，该输电塔包括：塔身；复合横担；连接转动组件，连接塔身与复合横担，并使复合横担能够相对塔身转动，其中，复合横担相对塔身转动的转动轴线与塔身的中心轴线相交，且两者之间的夹角为锐角。本申请所提供的输电塔能够降低在非正常运行工况下复合横担与塔身撞击的概率。
