Abstract
A method for producing a wound insulating conduit, in particular for a high-voltage insulator, with at least one empty channel for subsequent insertion of a conductor, e.g., an optical fiber. First layers of a material to be wound are applied first, then a molded body provided with at least one empty conduit is applied to a resulting surface and wrapped by additional layers. The molded body has lateral projections which extend over an entire length of the empty conduit and are designed so that they correspond to the surface to which it is secured.
Claims4
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;
- and
- winding additional layers of the material onto the winding mandrel until a final diameter of the insulating conduit is achieved.
