。Metal spraying is applied to the upper and lower end surfaces of a current-limiting element made of a sintered body mainly composed of zinc oxide, and the upper and lower terminals are connected to this, respectively, and the entire outer circumference of the element excluding the connection part of both terminals. A semicircular arc-shaped current limiting element unit, which is integrally molded with an insulating material, is fixed to the lower end opening of the cylindrical porcelain body.
Connecting the upper terminal of the element unit that is fitted into the semi-circular storage part provided in the extension of the upper part of the lower cover made of synthetic resin, which is arranged concentrically with respect to the inner peripheral wall of the lower part of the porcelain body, and which is further fitted. The lower terminal is connected to a lower fixed electrode of the main body, and the lower terminal is connected to a discharge electrode, and the connected discharge electrode is opposed to the flash angle of the arm mounting bracket through a discharge gap. Cylindrical cutout with built-in current limiting element.
