Abstract: Nowadays,high-alumina electric porcelain has become a core component to ensure the safe operation of the power grids.Due to its brittleness and high sensitivity to defects,traditional electric porcelain struggles to meet the reliability requirements for extreme environments,therefore,the research and development of high-strength and high-toughness high-voltage electric porcelain has become the key to ensuring the long-term stable operation of the power grids.Three effective methods for enhancing the performance of high-alumina high-voltage electric porcelain materials and their mechanisms were summarized:the optimization of the preparation process improves the mechanical properties and reliability through improving the densification and uniformity of the materials;the optimization of raw material selection,which adjusts the ratio and improves the purity,enhances the mechanical strength and electrical insulation;and additive toughening technology,especially whisker toughening and nanoparticle dispersion toughening,significantly improves the fracture toughness and resistance to crack propagation.

Key words: high-voltage electric porcelain, high-alumina, strengthening and toughening, fracture toughness, electrical insulation
