ABSTRACT:
A method of manufacturing insulators with excellent high-voltage performance having a core member, a sheath arranged on an outer surface of the core member and a shed arranged on an outer surface of the sheath is disclosed. In a first aspect of the invention, a method includes the steps of arranging the sheath made of non-cured polymer materials on an outer surface of the core member, arranging a plurality of the sheds made of cured polymer materials on an outer surface of the sheath, and curing the sheath to connect the sheath to the sheds. In a second aspect of the invention, a method includes the steps of arranging the sheath made of cured polymer materials on an outer surface of the core member, arranging a plurality sheds made of cured polymer materials on an outer surface of the sheath, and connecting the sheath to the sheds by using adhesives. In both aspects, a small diameter portion in which a diameter becomes gradually smaller is arranged on all or a part of an inner circumferential surface of the shed to which the sheath is connected, and a securing force of the shed with respect to the sheath is largest at a minimum diameter portion of the small diameter portion as compared with the other portions.
