Description

Technical Field

[0001] The utility model relates to the technical field of hard engineering plastic bell-shaped insulators, in particular to a hard engineering plastic bell-shaped insulator. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, and are able to withstand voltage and mechanical stress. Insulators are of various types and shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. Rigid engineering plastic bell-type insulators are an insulating device used on power transmission and distribution lines, usually used to support and fix conductors while providing electrical insulation. Therefore, a rigid engineering plastic bell-type insulator is needed, which has a simple one-time molding process in production and improves the strength, weight and electrical performance of the insulator.

[0003] In the composite insulator disclosed in publication number CN202307378U, one or more diaphragms are used to completely cover a certain annular portion of the porcelain or glass surface of the umbrella disk of the insulator, and the annular portion is a closed annular surface surrounding the steel foot of the insulator. The use of this solution to transform the disk-shaped suspension insulator not only improves the anti-pollution flashover performance of the insulator but also maintains the performance for more than fifteen years.

[0004] However, the composite insulator has the following disadvantages: it is not easy to improve the strength, weight and electrical performance of the insulator and reduce the maintenance workload during production; at the same time, it is not easy to simplify the one-time molding process and improve the application prospects during production.
