Abstract

The invention discloses a post insulator and a composite cross arm. The post insulator comprises: an insulator; an umbrella skirt wrapping the periphery of the insulator; and a first connecting fitting connected with the end of the insulator and comprising a flange cylinder, wherein the flange cylinder is of a hollow structure in the axial direction and is arranged at the end of the insulator in a sleeving mode, the inner wall of the flange cylinder is provided with a plurality of cementing grooves formed in the axial direction at intervals, the cementing grooves are equal in width, and the width of each cementing groove is smaller than the width of the interval between every two adjacent cementing grooves. Through the arrangement, the strength of the post insulator can be improved.

Description

technical field [0001] The present application relates to the technical field of power transmission, in particular to a post insulator and a composite cross arm. 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 transmission towers made of composite materials needs to be improved, especially the strength of post insulators in composite cross...
