Insulator Function and Requirements

The main function of the insulator such as D Iron Insulator is to achieve electrical insulation and mechanical fixing, for which various electrical and mechanical properties are specified. 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; in the specified machine After long-term operation under electric load and various environmental conditions, no obvious deterioration occurs; the insulator such as Silicon Rubber Insulator of the insulator does not produce obvious corona discharge phenomenon under the operating voltage, so as not to interfere with the reception of radio or television. Since insulators are widely used devices, their connection fittings are also required to be interchangeable. In addition, the technical standards of insulators are required to test various electrical, mechanical, physical and environmental conditions of insulators to verify their performance and quality, depending on the type and conditions of use.
