Technical Examples
Disclosed is a method for manufacturing a composite high voltage insulator in which a plurality of skirts are manufactured and joined to a rod, and more particularly to a method for manufacturing a composite high voltage insulator in which an expanding pipe is inserted into a plurality of skirts arranged in a line by a skirt holder to expand the inner diameters of the skirts, so that the skirts are mounted on precise positions of the rod, and an adhesive agent is easily applied, so that an interface between different materials is not formed in order to improve reliability of insulator products.
