Application Fields

Glass insulators are widely used in high-voltage and ultra high voltage transmission lines, including transmission lines with voltage levels of 110kV, 220kV, 500kV, and even higher. They can be seen in urban power supply networks, cross regional transmission projects, and output lines of large power plants. For example, in the transmission lines connecting large hydropower stations and urban power grids, glass insulators play a crucial role in ensuring the safe and efficient transmission of electricity to thousands of households.
