Abstract
This paper presents the analysis on the properties of porcelain insulators with the manufactured year. The domestic porcelain insulators manufactured in 1995, 1997, and 2002 and the imported one are prepared. The content of alumina was increased with the manufactured year, and the hardness of ceramic parts showed the same trend. Moreover, the distribution and the size of pore were more decreased and reduced on the junction parts between the glaze and the ceramic. Therefore, we concluded that the domestic porcelain insulators have been improved with the lapse of time.
