ABSTRACT:
The disclosed polymer LP insulator having an FRP rod, an insulation overcoat member made of rubber, which is arranged on an outer surface of the FRP rod, and securing metal members clamped at both end portions of the FRP rod, wherein an end portion of the insulation overcoat member is inserted into an end portion of the securing metal member, includes an elastic member arranged in a space defined by the FRP rod, an inner surface of the securing metal member, and an end surface of the insulation overcoat member, wherein a pressure for clamping and fixing is only applied to a connection portion between the securing member and the FRP rod.
The disclosed polymer LP insulator is produced for example by arranging the securing metal member at both ends of the FRP rod; clamping and fixing the securing metal member to the FRP rod by applying a pressure only to a connection portion between the securing metal member and the FRP rod; and forming the insulation overcoat member made of rubber on an outer surface of the FRP rod, and an elastic member in a space defined by the FRP rod, an inner surface of the securing metal member, and an end surface of the insulation overcoat member simultaneously.
