Semiconducting glaze insulators show excellent electrical performance under contaminated conditions. In order to mass‐produce this type of insulator, it is first necessary to determine the kind of materials that have such semiconducting properties and to decide on an optimum resistivity of the semiconducting glaze from a practical manufacturing standpoint. This paper describes the results of a series of investigations into the macroscopic surface resistivity needed to develop the expected superior electrical characteristics of these insulators, and the optimum distribution of volume resistivity of the glaze over the actual insulator surface, among others. The chemical composition of the glaze ingredients and the manufacturing conditions are critical for realizing the resultant glaze characteristics. © 2000 Scripta Technica, Electr Eng Jpn, 131(1): 10–18, 2000
