insulator features

 glass insulator for electrified railway catenary


 ◆Good vibration fatigue resistance performance 

After 15 million vibration fatigue and 2 million high-frequency mechanical vibration tests, the electromechanical strength of the glass insulator remains basically unchanged and electromechanical properties attenuation does not occur.

 ◆Large main capacitance and uniform voltage distribution 

Dielectric constant of glass is kept between 7 and 8 to make the main capacitance of Glass Insulator for Electrified Railway Catenary maintained at a relatively high level and uniformly distribute voltage to lower the voltage withstood by the insulators on the wire side and ground site, weaken the radio interference impact, reduce the corona loss and lengthen the service life of Glass Insulator for Electrified Railway Catenary.

 ◆Good self-cleaning performance and not easy to age 

According to the reflection from Electric Power Department, the glass insulator is not accumulate dirt and easy to clean. glass insulators in southern lines are cleaner. The Glass Insulator for Electrified Railway Catenary in typical lines will be periodically sampled for mechanical and electrical performance inspection. The result shows that the performance remains almost unchanged after years of using and no aging phenomenon has been found.
