Problems solved by technology
For example, composite cross-arms are generally formed by a combination of post insulators and cable-stayed insulators, including various forms. The ends of composite cross-arms are generally equipped with end fittings for hanging transmission lines, and composite cross-arms will bear A certain torque, under this premise, puts forward higher requirements for the connection process of the end fittings. In addition, the current composite cross-arm has low production efficiency and high production cost.

The invention discloses a composite cross arm and a power transmission tower. The composite cross arm comprises a post insulator and a cable-stayed insulator, one end of the post insulator and one end of the cable-stayed insulator are both used for being connected with a tower body of the power transmission tower, the other end of the post insulator and the other end of the cable-stayed insulator are connected through an end fitting, the end fitting comprises at least two flange cylinders which are coaxially arranged and sequentially connected, the at least two flange cylinders are arranged on the periphery of the post insulator in a sleeving mode, one flange cylinder is connected with the cable-stayed insulator so that the post insulator can be connected with the cable-stayed insulator, and the peripheral face of one flange cylinder is smooth. According to the composite cross arm, the production efficiency can be improved, and the production cost can be reduced.
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, composite cross-arms are generally formed by a combinatio...
