Cap insulator: The insulation part is circular or cap shaped, which is commonly used in scenarios such as equipment connection in power systems and can provide good insulation protection.
Disc insulator: It has a disc-shaped insulating part and is widely used in high-voltage equipment. The disc-shaped suspension ceramic insulator, with its disc-shaped structure, helps to increase the creepage distance and improve insulation performance.
String insulator: composed of multiple insulator units connected in series. By connecting multiple insulators in series, the electrical insulation strength can be improved to meet the insulation requirements of high-voltage lines.
