Application
Porcelain insulators are commonly used in high-voltage transmission lines in power systems. In the power system, transmission lines are important channels for transmitting electrical energy generated by power plants to user terminals. Since transmission lines often face the test of various harsh environments, such as strong winds, high temperatures, acid rain, etc., the requirements for insulators are relatively high. Porcelain insulators have high mechanical strength and heat resistance, which can effectively resist erosion and damage from the external environment, maintain good insulation status of lines, and ensure safe transmission of electric energy.
