초록

This paper deals with the electric insulator in terms of its toughness. The toughness is determined by the notched beam test and it is found that the toughness of electric insulator largely depends on the porosity as well as crystalline phases. This study also indicates that the Korean electric insulators have improved its toughness for last seven years and the recent products show comparable properties with imported insulator.
