Abstract
A method of manufacturing a wound insulator pipe, in particular for a high voltage insulator, having one or more ducts for conductors of any kind is provided. A laminate structure is achieved by winding a material onto a spindle and impregnating with a resin. Initially first layers of the material to be wound are applied; then at least one groove is made in the surface obtained and then the winding is completed until the final diameter is attained.
Claims3
A method for manufacturing a wound insulator pipe for a high-voltage insulator, the wound insulator pipe 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 spindle first layers of a material until a first diameter is achieved, the material including one of rovings, tape, fiberglass, and synthetic material;
- impregnating the first layers with resin to form an armor;
- curing the armor so that a surface obtained can be mechanically machined;
- machining at least one groove in the cured surface, the at least one groove extending one of longitudinally and in a spiral;
- and
- winding additional layers of the material onto the spindle until a final diameter of the insulator pipe is achieved, with the at least one groove therein forming a channel.
