        abstract = {Silica and Alumina based Porcelains are being majorly used in electrical applications. However, these porcelains have lower electrical strength due to the increased glass phase. This study aims to investigate a mechanically and electrically strong enough porcelain insulator by optimizing the chemical composition of Alumina and Silica. Here, three electrical porcelains have been prepared with different amounts of Alumina and Silica compositions and fired in an industrial furnace at 1300°C. The characterization techniques were adopted to evaluate the variations in structural and micro-structure, respectively, through enhancing and lowering the weight concentration of Silica and Alumina for the base composition of the porcelain insulator. The tensile strength and physical behavior measurement was analyzed for all the samples. The Alumina and Silica composition sample with 35 and 10 weight% indicates a maximum density of 2.50 grams per cubic centimeter with water absorptive of 1.83%. The highest tensile, compressive, and electrical strength values of 35 Mega Pascal, 178 Mega Pascal, and 23.1 kiloVolt per millimeter were achieved. Scanning Electron Microscopy revealed dense particles and uniform distribution of long and thin needle-shaped mullite are predominant in sample microstructures with the highest electrical strength.},
