Claims

[Claims for Utility Model Registration] 1. A current-limiting element with non-linear voltage-current characteristics is housed inside a mounting tube, and an upper thin plate electrode and a lower thin plate electrode are mounted on both upper and lower ends of the mounting tube using glass, The caps are airtightly sealed with glass solder or an inorganic bonding material such as metal, and an upper cap electrode and a lower cap electrode that cover both thin plate electrodes are fitted to both ends of the mounting tubular part, and the ends of the mounting tubular part A cross section formed on the outer periphery of the cap electrode has an arcuate cross section and an annular caulking portion as a whole is caulked to an annular caulking protrusion formed on the outer circumference of the cap electrode, and an end portion of the caulking portion is caulked. A conductor for electrically connecting the upper and lower thin plate electrodes, the current limiting element, and the thin plate electrode is housed inside the inclined plane of approximately 3 to 5 degrees passing through the end with respect to the horizontal plane passing through. Features lightning protection insulators. 2. The lightning arrester has a cap fitting 7 attached to a covered cylindrical head 5c formed at the upper center of the shade portion 5a of the insulator body 5.
It is a suspension insulator constructed by fixing a pin fitting 8 on the inside of the head 5c, and the cap part 5a is provided with a mounting cylinder part 5d having a through hole 5e. The current limiting element 9 is inserted into the hole 5e, and the upper cap electrode 14 and the cap metal fitting 7, and the lower cap electrode 15 and the pin metal fitting 8 are connected to the lead wire 1, respectively.
2. The lightning arrester according to claim 1, wherein the lightning arrester is electrically connected by terminals 8 and 19.
