Background

The insulator is a device which is installed between conductors with different electric potentials or between the conductors and a grounding component and can withstand the action of voltage and mechanical stress, and can play an important role in an overhead transmission line. Early-year insulators are mostly used for telegraph poles and are slowly developed in high-voltage wire connecting towers. The main function of the insulator is to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical properties are specified. Under the action of specified operating voltage, lightning overvoltage and internal overvoltage, breakdown or flashover along the surface does not occur; under the action of specified long-term and short-term mechanical load, no damage and damage are generated; no obvious deterioration after long-term operation under the specified mechanical and electrical loads and various environmental conditions; the insulator hardware does not generate obvious corona discharge phenomenon under the operation voltage so as to avoid the interference of the radio or television reception. Since the insulator is a device used in large numbers, interchangeability is also required for its connection fitting. In addition, the technical standards of insulators also require various tests of electrical, mechanical, physical and environmental condition variations, depending on the model and the conditions of use, in order to verify the performance and quality of the insulators.
