Abstract
In a high-voltage hollow insulator, which has an insulating body, with a hollow support element made of a thermosetting composition, and a potential control device, the potential control device is encapsulated with the thermosetting composition of the support element and at least partially encoiled with fibers. For production, a blank of the support element is formed from the potential control device and the still soft thermosetting composition in accordance with the filament-winding process and is heated and cured. The hollow insulator can be produced in a simple and low-cost way. The structural design of the potential control device is no longer bound to mechanical requirements or requirements necessary for installation.
Claims10
A hollow high-voltage insulator, comprising:
- an insulating body with a hollow support element made of a thermosetting composition, and a potential control device encapsulated with said thermosetting composition of said support element;
- said potential control device being at least partially encoiled with fibers, and said support element built up by alternating insertion of said potential control device, coiling on of said fibers, and simultaneous or subsequent application of said thermosetting composition.
