COMPOSITE INSULATOR MANUFACTURING PROCESS Russian patent published in 2008 - IPC H01B19/00 H01B17/32 

FIELD: electrical engineering; polymeric insulators and their manufacturing process.

SUBSTANCE: proposed composite insulator manufacturing process includes skeleton fixation in winding mechanism that rotates it about longitudinal axis at the same time moving skeleton along its axis, production of profiled band from T-section silicone rubber band by means of extruder, installation of fin in a spaced relation between turns followed by its rolling-on. Skeleton rotating and moving mechanism is inclined relative to extruder through angle equal to that of fin inclination. Fin is thickened at least on one end of base and this end is flattened in the course of rolling to fill up clearance between adjacent turns. Then part obtained is polymerized and wiring hardware is mounted thereon.

EFFECT: facilitated manufacture, improved termination of silicone finning edge.
