Abstract

The invention discloses a power transmission tower. The power transmission tower comprises a tower body, a composite cross arm, a connecting and rotating assembly and a limiting assembly, wherein theconnecting and rotating assembly is used for connecting the tower body with the composite cross arm and enabling the composite cross arm to rotate around a rotating axis relative to the tower body, and the limiting assembly is used for limiting the maximum rotating angle of the composite cross arm relative to the tower body. According to the power transmission tower provided by the invention, thepossibility of abnormal discharge in a normal operation condition and the probability of collision between the composite cross arm and the tower body can be reduced.

Description

technical field [0001] The present application relates to the technical field of power transmission, in particular to a power transmission tower. Background technique [0002] Transmission lines are an important lifeline for the development of the national economy. Once a transmission line in a certain area fails, it will cause immeasurable economic losses to the regional users it serves. Therefore, ensuring the normal operation of transmission lines is extremely important for daily life and economic development. Important, and the transmission tower is a necessary condition to ensure the normal operation of the transmission line. [0003] Most of the current transmission towers include a tower body and a cross arm for hanging transmission lines, wherein the cross arm is arranged on the tower body and extends outward for a certain length. The inventors of the present application have found that currently, under extreme weather such as typhoons, the tower body is damaged due...
