A method for manufacturing a post insulator and a post insulator

摘要

A method for manufacturing a post insulator comprises the steps of introducing a core (7) into a tube (1) of an insulating stiff material while leaving a small circumferential space separating the core and the inner walls of the tube. Adhesive is then introduced under an overpressure into the interior of the tube and is cured while maintaining an overpressure in the interior of the tube.
