Abstract
The invention discloses a composite cross arm and a power transmission tower. The composite cross arm comprises two post insulators and two cable-stayed insulators, one ends of the two post insulators and the two cable-stayed insulators are used for being connected with a tower body of the power transmission tower, and the other ends of the post insulator and the cable-stayed insulators are connected together to form the composite cross for hanging the end part of the power transmission line, wherein, the two cable-stayed insulators are located on the same side of the two post insulators and are arranged adjacent to the two post insulators correspondingly, meanwhile, the included angle between the two post insulators is 20-50 degrees, and the included angle between each post insulator and the adjacent cable-stayed insulator is 15-45 degrees. The composite cross arm provided by the invention is high in stability, and can provide favorable conditions for mounting a first grading ring on the post insulator and mounting a second grading ring on the cable-stayed insulator.
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. And the current composite cross-arm is generally formed by a combinati...
