Porcelain spool insulators are low-voltage insulators. Low-voltage insulators are often used in overhead power lines with DC or power frequency AC-rated voltages lower than 1000V to play the role of insulating and fixing wires. Low-voltage insulators can usually be divided into three types according to their structure types: low-voltage pin insulators, low-voltage butterfly insulators, and low-voltage spool insulators. Other types such as screw type, tension, and tram line insulators also belong to low-voltage insulators./

In actual use, porcelain spool insulators also have many electrical and mechanical performance requirements. For example, under the specified operating voltage, lightning overvoltage, and internal overvoltage, bobbin insulators cannot have internal breakdown or flashover along the surface. ; Under the specified long-term or short-term mechanical load, the spool insulator cannot be damaged or damaged; after long-term operation under the specified electromechanical load and various environmental conditions, the bobbin insulator cannot produce obvious deterioration.
