Abstract:
A method for producing a wound insulating conduit for a high-voltage insulator; the wound insulating conduit having at least one channel for at least one of conductors and optical fibers to be subsequently drawn in, comprising the steps of:winding onto a winding mandrel first layers of a material until a first diameter is achieved, the material including one of rovings, a ribbon of glass, fibers of glass, and synthetic material;impregnating the first layers with resin to form a sheathing;positioning and securing a molded body on an outer surface of the sheathing, the molded body having at least one empty conduit forming a channel, wherein lateral projections extend in a longitudinal direction over an entire length of the at least one empty conduit; andwinding additional layers of the material onto the winding mandrel until a final diameter of the insulating conduit is achieved.
