Power transmission tower

Abstract

The invention discloses a power transmission tower. The power transmission tower comprises a tower body, a cross arm connected to the tower body, and a wire clamp hardware connected to the tail end of the cross arm, wherein the wire clamp hardware is used for connecting a power transmission wire; the cross arm comprises an insulator, and a rotating device arranged on the insulator; the wire clamp hardware is rotated around an axis of the cross arm through the rotating device. The power transmission tower can overcome the shortage of poor twisting resistance of the combined cross arm, and can greatly improve the adaptability of the combined cross arm.

Description

technical field

[0001] The invention relates to a power transmission device, in particular to a power transmission tower. Background technique

[0002] In the power transmission equipment, the composite cross-arm is used as a structure to support the operation of the transmission line. Compared with the traditional iron tower, due to its excellent insulation performance, the tower is less affected by the wind load, the height is significantly reduced, the width of the corridor is reduced, and the weight of the whole tower is reduced. Reduced, the basic force is also reduced accordingly, which improves the safety performance, and at the same time has the advantages of corrosion resistance, strong environmental adaptability, maintenance-free, and good designability.

[0003] Composite cross-arms use hollow insulators as stress components, and their torsional performance is average. If they are used on transmission towers with high stress, they cannot meet the mechanical perfor...
