Abstract

The invention relates to a 1100KV rod post porcelain insulator and belongs to the technical field of electroceramics. The 1100KV rod post porcelain insulator is prepared by compounding, grinding, molding and sintering. The 1100KV rod post porcelain insulator comprises the following components in weight percentage: 45-53 percent of calcined bauxite, 8-15 percent of feldspar, 5-12 percent of Zhangcun clay, 7-13 percent of calcined Datong clay and 16-25 percent of Zuoyun clay. According to the 1100KV rod post porcelain insulator, the strength of a test strip reaches up to 220MPa, and the requirement of the 1100KV rod post porcelain insulator on the material strength can be well met.
