Abstract

The invention discloses a composite cross arm. The composite cross arm is installed on a tower body, the composite cross arm comprises a post insulator, three cable-stayed insulators and a cross arm connecting fitting, one end of the post insulator is connected with one ends of the cable-stayed insulators to form the composite cross for hanging the end part of the a power transmission line, and the three cable-stayed insulators are arranged around the post insulator at intervals; and the cross arm connecting fitting is used for connecting the other end of the post insulator and the other ends of the cable-stayed insulators with a tower pole, so that the composite cross arm is mounted on the tower body. The invention further discloses a power transmission tower. According to the composite cross arm and the power transmission tower, the stable performance of the power transmission tower can be improved.

Description

technical field [0001] This application relates to the technical field of power transmission, in particular to a composite cross arm and a power transmission tower. Background technique [0002] Due to the advantages of light weight, high strength, corrosion resistance, easy processing, designability and good insulation performance, composite materials are one of the ideal materials for building transmission tower structures, and the towers made of composite materials have the advantages of light tower weight, tower head It has the advantages of small size, light structure, easy processing and molding, low transportation and assembly costs, corrosion resistance, high and low temperature resistance, high strength, low possibility of theft, and low line maintenance costs. [0003] The inventors of the present application found that the performance of towers made of composite materials needs to be improved. For example, the composite cross-arm includes an insulating rod, which ...
