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.
