The semiconducting glaze insulators show excellent electrical performance under contaminated condition. In order to make mass production of such type of insulators, it is first necessary to determine the kind of the materials to develop such a semiconducting property and to decide an optimum resistivity of the semiconducting glaze from practical manufacturing technology point of view.
This paper describes the results of a series of investigation into the macroscopic surface resistivity to develop the expected superior electrical characteristics of insulators, the optimization of the volume resistivity of glaze itself, the optimum distribution of volume resistivity of the glaze over the actual insulator surface, etc. The chemical composition of the glaze ingredients and the manufacturing conditions are essential for the resultant glaze characteristics.
