Different types of insulators in China have withstood long-term icing, high altitude, pollution, high temperature, low temperature, ultraviolet, rain, lightning, earthquake and typhoon and other special operating environment tests, successful operation experience has proved that different types of insulators have excellent electrical, mechanical, weather, seismic characteristics.
Different types of insulators in China have withstood long-term icing, high altitude, pollution, high temperature, low temperature, ultraviolet, rain, lightning, earthquake and typhoon and other special operating environment tests, successful operation experience has proved that different types of insulators have excellent electrical, mechanical, weather, seismic characteristics. Different types of insulators have their own advantages and disadvantages, of which suspension porcelain insulators have 95 years of operating experience, umbrella-shaped rich, its inherent defects are not easy to find, need to carry out deterioration detection and other operation and maintenance work. The suspension glass insulator has the characteristics of zero-value self-explosion, there is no zero-value detection problem, and its umbrella shape is relatively single, mainly deep prismatic. The above two types of insulators have excellent mechanical and electrical properties and have a service life of more than 30 years. Composite insulators have the unique advantages of excellent mechanical and electrical performance, excellent antifouling performance, light weight, simple manufacturing process, diameter and structure height not easily limited by manufacturing process, strong flexibility, good heat dissipation, excellent explosion-proof performance and simple operation and maintenance. It is a non-breakdown insulator, there is no zero value detection problem, and the service life is more than 20 years. Suspension composite insulators, pillar composite insulators, hollow composite insulators and pillar porcelain insulators have been widely used in AC/DC high voltage, EHV and UHV power transmission and transformation projects. It reflects the development of composite insulators for more than 20 years, and its excellent performance and high reliability have been accepted and affirmed by users.
