Abstract
A method for manufacturing a long size non-ceramic insulator is provided. The method includes the first step, in which a rubber housing having a plurality of trunks and skirts is formed around a long size core while molds are tightly assembled, and 1 second, in which the long size core is moved a length corresponding to the rubber housing while the molds are separated. Further according to a third step, the long size core is set in a position in the molds as the distal portion of the formed rubber housing is clamped by positioning jigs disposed in the molds while the molds are tightly assembled. While the rubber housing is clamped, the next continuous rubber housing is formed around the long size core, which will be connected to the last formed rubber housing.
