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 ofGlass Insulator for Electrified Railway Catenary.

Good self-cleaning performance and not easy to age
