초록
In order to analyze the physical and chemical characteristics of the home production porcelain insulators by change of the alumina addition amount, 36000lbs ball socket type suspension insulators which were manufactured in 1989, 1995 and 2001 removed in transmission line and an experiment was performed. By the result, 8 [wt.%] alumina that influences the mechanical properties and arc resistance properties in case of insulators that were manufactured in 1989 was contained, and the relative density and the fracture toughness of insulators appeared by 94.2% and 1.4 [MPa
