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 columns12-1, 12-2, in which plural polymer post insulators1-1to1-4are stacked, are arranged in parallel. The polymer post insulator columns12-1, 12-2arranged in parallel are connected with each other via connecting plates13-1to13-3at each connection site of the polymer post insulators1-1to1-4constituting the polymer post insulator columns12-1, 12-2as well as at the top and bottom of the polymer post insulator columns12-1, 12-2. Thus, the cantilever strength in a direction of arranging the polymer post insulator columns12-1, 12-2in parallel is increased, and also the compression strength in a direction of stacking the polymer post insulators1-1to1-4is increased.
