問題点があった。(Prior Art) Conventionally, lightning arrester insulators have been proposed in which a plurality of cylindrical lightning arrester elements are built in series in a resin mold. In this lightning arrester, in order to prevent deterioration of the lightning arrester element due to moisture absorption and to prevent the resin mold from entering between the lightning arrester elements, the outer periphery of the lightning arrester element is covered with a heat shrinkable tube and the lightning arrester element is fixedly connected. (Patent Publication No. 57-48588) (Problems to be Solved by the Invention) However, since the lightning arrester element is a fired product, it is difficult to obtain a product with a uniform perfect circular shape. For this reason, in the conventional fixed connection method of lightning arrester elements, the heat-shrinkable tube cannot fit closely along the shape of the element, and a gap is partially created between the step part of adjacent lightning arrester elements and the inner periphery of the heat-shrinkable tube. arise. As a result, corona discharge occurs, accelerating the deterioration of the lightning arrester, and when the volume of the void repeats due to expansion and contraction due to heat,
There was a problem in that moisture entered the void, causing the lightning arrester to absorb moisture and deteriorate.

製造等において作業能率を向上できる。Effects of the Invention As detailed above, according to the present invention, the fluid rubber adhesive dries throughout the shape of the lightning arrester element, thereby creating a void between the lightning arrester element and the rubber adhesive. Lightning arrester elements can be fixedly connected in one piece without causing any damage. Therefore, it is possible to prevent deterioration of the lightning arrester element due to moisture absorption and corona discharge, prevent displacement of the lightning arrester element due to vibration, etc., and furthermore prevent rubber from entering between the contact surfaces of the lightning arrester element during rubber molding. . Furthermore, the lightning arrester element can be handled in a fixedly connected state, and work efficiency can be improved in transportation, manufacturing of lightning arrester insulators, etc.
なお、ゴム系接着剤の弾性により避雷素子を破壊するこ
ともなく、ゴム系接着剤の塗布厚は幾層にも重ね塗りす
ることによりに調節できる優れた効果がある。Furthermore, due to the elasticity of the rubber adhesive, the lightning arrester element will not be destroyed, and the coating thickness of the rubber adhesive can be adjusted by applying multiple layers, which is an excellent effect.
