Abstract

By laminating a certain number of layers of the nonlinear resistive elements (1), the stacked layer is formed. The electrode terminals (2) composed of the fixing portions (2a) and the plate portions (2b) are disposed respectively on the upper and lower edges of this stacked layer, so that the inner elements of the surge arrester can be formed. A plurality of the slender and the plate type insulation supporting elements (4) having a rigidity and are made of a fiber reinforced plastic (FRP) are disposed so that they define a plurality of openings (3), which extend to an axial direction of the surge arrester on a periphery of the zinc oxide elements (1) and they are fixed to the opposite sides of the electrode terminals (2), respectively. By molding a periphery of the zinc oxide elements (1) and the insulation supporting elements (4) with a silicone resin having an excellent flow property, the silicone resin container (5) composed of the drum portion (5a) and the cap portion (5b) is formed. <IMAGE> <IMAGE> <IMAGE>
