The main function of insulators is to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are specified. For example, under the specified operating voltage, lightning overvoltage and internal overvoltage, there is no breakdown or flashover along the surface; under the specified long-term and short-term mechanical load, there is no damage and damage;
The main function of insulators is to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are specified.
For example, under the specified operating voltage, lightning overvoltage and internal overvoltage, no breakdown or flashover along the surface will occur; Under the specified long-term and short-term mechanical load, no damage and damage will occur; After long-term operation under the specified mechanical and electrical loads and various environmental conditions, no obvious deterioration will occur; The metal fittings of insulators, no significant corona discharge is produced at 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 insulators according to the different types and conditions of use.
