Problems solved by technology

[0002] With the rapid development of the electric power industry and the continuous improvement of voltage levels, my country's requirements for porcelain insulators used in high-voltage and ultra-high-voltage power transmission and transformation systems are also getting higher and higher, but the porcelain performance of existing porcelain insulators has not reached Requirements, especially the flexural strength of porcelain, is generally only at the level of 140Mpa ~ 160Mpa, which cannot meet the requirements of 220 ~ 1000KV power transmission and transformation system at all.
At present, such products can only rely on imports to meet domestic demand, which not only causes a large loss of funds, but also seriously hinders the development of the electric power industry.
