International Situation of Insulators Industry

Porcelain insulators is the product of the industrial revolution in the 19th century. After human master the power generation technology, the transmission of electricity to the electric field can not be separated from the insulating medium. The earliest used insulating medium is the porcelain insulator . With the increase of power generation capacity and transmission distance, the voltage level is increasing, and the requirements for mechanical and electrical properties of ceramic insulators are also increasing.
