Compound lightning -proof insulator

The utility model relates to a compound lightning -proof insulator is refered in particular to in electric wire netting lightning protection field, including upper portion gold utensil, lower part gold utensil, casing, the upper portion gold utensil passes through the bolt to be connected with the perverse fastener of needle, and a confined cavity is constituteed to upper portion gold utensil, casing and lower part gold utensil fixed connection in proper order, from last resistance card and the resistor ring of having put in proper order extremely down in the cavity, resistor ring embeds there is discharge electrode, discharge electrode axial in pairs arranges in the resistor ring. After adopting above -mentioned scheme, improve the electric conductivity of lightning protection vase, reduced thunderbolt line breaking line's probability. 本实用新型涉及电网防雷领域，特指种复合防雷绝缘子，包括上部金具、下部金具、壳体，所述上部金具通过螺栓与针剌线夹连接，上部金具、壳体和下部金具依次固定连接组成个封闭的腔室，在腔室内从上至下依次置有电阻片和电阻环，所述电阻环内置有放电电极，所述放电电极成对轴向置于电阻环内。采用上述方案后，提高了防雷瓷瓶的导电性，减少雷击线路断线的概率。
