Abstract

A high voltage hollow composite insulator of diameter variable type is prepared as sticking end connection pieces firmly at two ends of winding tube, setting a unified structure of umbrella body at external of winding tube, setting said winding tube to be tube body in variable diameter, using high temperature silicon sulfide rubber to form a unified structure of umbrella body by injection forming process.

Description

technical field [0001] The invention relates to a hollow composite insulator used in a high-voltage power station in the electric power industry, in particular to a tower-shaped high-voltage hollow composite insulator with variable diameter and a manufacturing method thereof. Background technique [0002] After searching the relevant patent documents, no variable-diameter high-voltage hollow composite insulator with the same structure as the present invention and its manufacturing method have been found. Existing insulators for high-voltage equipment are mainly divided into two categories: porcelain sleeves made of porcelain materials and silicone rubber hollow composite insulators. There are many structural forms of porcelain bushings, such as straight shape, conical shape and waist drum, etc., but the weight of porcelain bushings is heavy, and it is easy to damage other equipment after explosion. It has low pollution resistance and complicated firing process; the hollow co...
