The Functions and Requirements of Insulators
- Jul 30, 2018 -

The main function of insulators is to achieve electrical insulation and mechanical fixation. Therefore, various electrical and mechanical requirements are required. There is no breakdown or flashover on the surface under the prescribed operating voltage, lightning overvoltage and internal overvoltage; it does not produce damage and damage under the prescribed long-term and short-time mechanical load; no obvious deterioration is produced after long-term operation under the prescribed machine, electric load and various environmental conditions; insulation is not produced; The metal fittings under the operating voltage do not produce obvious corona discharge, so as not to disturb the reception of radio or television. Because insulators are widely used devices, their connection fittings also require interchangeability. In addition, the technical standard of insulators also requires a variety of electrical, mechanical, physical and environmental conditions to test the performance and quality of insulators according to the different types and conditions of use.
