Abstract
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.
Claims7
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.
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.
