This SiO2 and Al2O3 kinds ceramic is the most popular and low cost material.
As a high tension insulator, it is used for suspension-type insulator, pin-type insulator, or bushing. Also it is used for home appliance heater supporter, porcelain bushing, plug, socket, and wiring parts as a low or middle tension insulator. In case of it is used in outside, we will coat its by a glaze.
