Insulators play a vital role in controlling insulation and are particularly important in overhead transmission lines. Initially, they were only used on telegraph poles, but over time, numerous disk-shaped insulators were installed on one end of the high-voltage wire connection tower to enhance creepage distance. These insulators are often made of glass or ceramics and are known as insulators. To be effective, insulators must withstand various electromechanical stresses resulting from environmental changes and electrical load conditions. Otherwise, they will fail and negatively impact the lifespan and use of the entire line.
The main function of insulators is to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are specified. If under the specified operating voltage, lightning overvoltage and internal overvoltage, no breakdown or flashover along the surface; under the specified long-term and short-term mechanical load, no damage and damage; under the specified machine , After long-term operation under electrical load and various environmental conditions, no obvious deterioration will occur; the fittings of insulators will not produce obvious corona discharge under the operating voltage, so as not to interfere with radio or television reception. Because insulators are widely used devices, their connection fittings are also required to be interchangeable. In addition, the technical standards of insulators also require various electrical, mechanical, physical, and environmental conditions to test the performance and quality of the insulators according to different types and conditions of use.
