Abstract
A lightning arrester insulator in which a voltage non-linear resistor having a major constituent of zinc oxide is integrally fixed in a longitudinal bore in the insulator with a layer of an inorganic adhesive agent which is interposed between an outer surface of the resistor and an inner wall surface of the insulator defining the longitudinal bore. A contact angle of the adhesive agent layer defined by each end face thereof and an associated end part of the inner wall surface is held within a range of 10 to 60 degrees. To establish the contact angle, at least one of the end face of the adhesive agent layer and the associated end part of the inner wall surface of the insulator is inclined with respect to the longitudinal centerline of the longitudinal bore. Each end surface of the voltage non-linear resistor is spaced from the corresponding end of the adhesive agent layer axially inwardly along the longitudinal centerline of the longitudinal bore.
