What types of insulators are there?

2021-11-09

(1) Insulators are usually divided into breakdown type and non-breakdown type.
(2) According to the structure, it can be divided into column (pillar) insulators, suspension insulators, pin insulators, butterfly insulators, tension insulators, pollution-proof insulators and bushing insulators.
(3) According to the application, it is divided into line insulators and power station and electrical insulators. Among them, the breakdown type insulators used for the line include pin type, butterfly type and disc type suspension type, and the non-breakdown type includes cross arm and rod suspension type. Type. Breakable insulators used in power stations and electrical appliances include pin pillars, hollow pillars and sleeves, and non-breakable types include rod-shaped pillars and container porcelain sleeves.
(4) The insulators used in overhead lines include pin insulators, butterfly insulators, suspension insulators, porcelain crossarms, rod insulators and tension insulators.

(5) The commonly used insulators are: ceramic insulators, glass fiber reinforced plastic insulators, composite insulators, semiconductor insulators.
