Evaluation of the electrical porcelain properties of alumina-silicate nano-clay

Abstract

The experimental evaluation of the electrical porcelain properties of alumina-silicates nano-clay was investigated. The nano-clay was produced using the sol-gel method. The properties analyzed were shrinkage test, porosity, plasticity, density, water absorption test and rupture test, mechanical falling load, dry frequency flashover voltage test and insulation test. The results obtained meet the requirement for low-voltage electrical porcelain, e.g., result of the mechanical falling load met the minimum required load of 13.5 kN specified for electricity transmission. The dry frequency flashover voltage of the sample was 26.7 kV which fell within the specified value of 25–30 kV. Finally, since the nano-clay was able to meet most of the criteria of electrical porcelain insulator, it can be used in the production of low-voltage porcelain.
