Abstract

Official abstract text for this publication.

A hollow insulator for high electric voltages has an insulating tube and a covering of the insulating tube made from a fiber-reinforced plastic. The covering is placed on an outer surface of the insulating tube. There is also described a method for producing the type of hollow insulator.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a hollow insulator for high electrical voltages, the method comprising: manufacturing an insulating tube; and sheathing the insulating tube with a fiber-reinforced plastic by arranging at least one prefabricated fiber mat around the insulating tube and then introducing plastic into the at least one fiber mat by a vacuum impregnation process. 2. The method according to claim 1 , which comprises manufacturing the insulating tube from a material selected from the group consisting of a ceramic material, a glass and a plastic. 3. The method according to claim 1 , wherein a flange is arranged at at least one end of the insulating tube prior to sheathing the insulating tube. 4. The method according to claim 3 , which comprises connecting the at least one flange to the insulating tube by cementing. 5. The method according to claim 1 , which comprises placing a flange at at least one end of the sheathing after sheathing the insulating tube. 6. The method according to claim 5 , which comprises connecting the at least one flange to the sheathing by an adhesive-bonding connection. 7. A method for producing a hollow insulator for high electrical voltages, the method comprising: manufacturing an insulating tube; and sheathing the insulating tube with a fiber-reinforced plastic by filament-winding the fiber-reinforced plastic around the insulating tube in a wet or dry state.
