insulator Insulator is a special kind of insulation control, can play an important role in the overhead transmission lines.Early years insulator for more poles, slowly development in high type high voltage wires to hang a lot at the end of the disc insulators, it is to increase the creepage distance, usually made of glass or ceramic call insulator.Insulator should not change due to environmental and electrical load conditions lead to a variety of electrical and mechanical stress and failure, or else there won't have a significant role in the insulator, will damage the whole line of use and operating life.
Details
1. The insulator is usually divided into can breakdown and not breakdown.
2. According to the structure can be divided into the pillar insulator (pillar), suspension insulator, pin insulator, butterfly insulator, tighten insulator, anti-pollutionCharged water irrigation insulator and bushing.
3. According to the application is divided into line insulator and power plant and electrical insulator.Which used in the circuit can be breakdown type insulator pin type, butterfly, disc hanging, not breakdown type with cross arm and bar hanging.Used in power plant, electrical breakdown type insulator can have a hollow needle type pillars, pillars and casing, not the breakdown type pillar and the container has a bar porcelain sets.
4. Used in overhead line insulator, commonly used have pin insulator, butterfly insulator, suspension insulator, porcelain crossarm, rod insulator and tension insulator, etc.
5. The commonly used insulator are: porcelain insulator, glass insulator, composite insulator, insulator semiconductor.
