Method of producing a composite high-voltage insulator, high-voltage insulator and plastic material for use in the inventive method, and method of producing a non-cylindrical component

摘要

The invention relates to a method of producing a high-tension insulator comprising an elongated central solid or hollow body (1), a synthetic material shield layer (6) and one or more synthetic material weathersheds (3) by the following steps: ;applying said synthetic material shield layer (6) to said solid or hollow body by molding or extrusion; ;molding said synthetic material weathersheds (3); ; one or both of the synthetic material of said shield layer (6) and the synthetic material of said weathersheds (3) being partly cross-linked and, if appropriate, the synthetic material of said shield layer (6) or weathersheds (3) not partly cross-linked substantially totally cross-linked, ;locating said weathersheds (3) at a predetermined site on said shield layer (6); and ;totally cross-linking the thus formed blank of said high-tension insulator.
