Abstract
An insulator for a gas insulated device and method of making and/or producing the insulator are disclosed. The insulator includes an injection molded insulator disc and a conductor. The insulator disc includes a center opening encompassed by an inner bead inside which the conductor is arranged. The insulator disc includes, for example, a first material which is injection molded onto the conductor.
Claims22
An insulator for a gas insulated device, the insulator comprising:
- an injection molded insulator disc;
- and
- a conductor, the insulator disc including a center opening encompassed by an inner bead inside which the conductor is arranged and an outer bead encompassing the insulator disc, and wherein the insulator disc is formed of a first material which is injection molded onto the conductor.
A method for the production of an insulator, the method comprising:
- providing a mold for injection molding of an insulator disc, the insulator disc comprising an inner bead surrounding a center opening;
- arranging a conductor in a cavity of the mold;
- injecting a first material into the mold to form the insulator disc, wherein the conductor is positioned inside of the center opening and the inner bead of the insulator disc and the conductor are firmly interconnected directly or indirectly;
- and
- removing of the insulator disc and the conductor from the mold.
A method for making of an insulator disc, the insulator disc having a center opening and an inner bead and an outer bead, and a conductor arranged in the center opening of the insulator disc, the method comprising:
- providing an injection mold, the injection mold having a first mold half, a second mold half interacting with the first mold half along a parting plane, a cavity corresponding to the insulator encompassed by the first and the second mold half, and at least one injection nozzle arranged at the first mold half configured to discharge liquefied material into the cavity directly or indirectly;
- closing the mold by relative movement of the first with respect to the second mold half until the cavity is closed;
- injecting liquefied material through the at least one injection nozzle;
- opening the mold by relative movement of the first with respect to the second mold half;
- and
- removing the insulator from the mold cavity.
