Abstract
The cantilever and compression strength of a polymer post insulator decreases according to lengthening of lever length of the polymer post insulator. By combining polymer post insulators to construct a structure having an increased strength in an arbitrary direction, a polymer insulator apparatus and a method for mounting the same can provide a sufficient strength and rigidity even as a long insulator for high voltage that requires a long insulation distance. Polymer post insulator columns--, in which plural polymer post insulators-to-are stacked, are arranged in parallel. The polymer post insulator columns--arranged in parallel are connected with each other via connecting plates-to-at each connection site of the polymer post insulators-to-constituting the polymer post insulator columns--as well as at the top and bottom of the polymer post insulator columns--. Thus, the cantilever strength in a direction of arranging the polymer post insulator columns--in parallel is increased, and also the compression strength in a direction of stacking the polymer post insulators-to-is increased.
