Abstract

PURPOSE: To improve the air-tightness and to facilitate the inspection, by empolying a multiple-enclosed structure in the container for containing the arrester element while containing a reactive member which discolors in accordance with the humidity in it and employing a transparent structure for enabling the eye inspection of said discoloration from the exterior.
CONSTITUTION: Cylindrical non-linear resistor 2 such as sintered zinc oxide is contained in a porcelain tube 1 made of transparent glass, then ring packings 3a, 8b are applied above while ring packings 3b, 8c are applied below to produce double enclosed structure. Reactive members 15a, 15c and 15b are arranged in the first and second enclosed spaces formed respectively between the packings 8b, 3a and the packings 8c, 3b, and between the packings 3a, 3b. Silica gel, for example, which discolors when it absorves more than predetermined water is employed as each reactive member. With such arrangement the deterioration of inner air-tightness can be eye inspected.
