Research On The Performance Of The New Cap And Pin Glass Insulator With Composite Shed In Engineering Application

In order to improve the problem of the insulator in heavily polluted area, base on the new technology and new applications, a new cap and pin glass insulator with composite shed is designed for the application in heavily polluted area. On the basis of the ordinary ceramic insulators and glass composite insulators, the new insulator is designed with new structure and productions technology. The new insulator has high-strength tempered glass pieces as insulating skeleton to withstand the mechanical loads. Its exterior sheds are designed as double or triple umbrella shaped. The tolerance flash capability is highly improved with high-quality high-temperature vulcanized silicone rubber.For the moment, issue on the material features, design, production technology and long term operation reliability is not yet under deep research, and the accumulated operating experience is lacking. Therefore, in order to promote the application of this new technology, from the whole life cycle of this new type cap glass composited insulator, all kinds of basic feature of this new insulator is analyzed and researched. The applications priority in heavily polluted area is proposed, and the principle and scope of the application is determined. While from the whole life cycle of this new type cap and pin glass insulator with composite shed, after the technology economy is analyzed and researched, the economical and social benefits are defined. It plays an active role in the accumulation of insulator design and operating experience, and it also provides the theoretical basis of the promotion for the applications in State Grid Corporation of China, and it provides the guide of engineering design and construction.
