Document Type and Number:
Japanese Patent JP4307707
Kind Code:
B2
Abstract:
The invention concerns a method for manufacturing an electrical insulator that includes a body (1) and a coating (5, 5a) of insulating material arranged on the body (1) where the coating is applied onto the body in a screw-like form or a helical-like form, whereby the coating is applied by extrusion directly on the body (1). In this way, the build-up trapped pockets of air between the applied coating and the body (1) is prevented, and good adhesion is achieved. The invention also concerns an apparatus for manufacturing an insulator as well as the use of the said method or apparatus for the manufacturing of a high voltage insulator.
