 ◆Good arc resistance performance 

The surface of double-umbrella disk suspension type glass insulator which has been subject to lightning burns in service is still smooth and covered with toughened internal stress protective layer. Therefore, the product maintains enough insulating performance and mechanical strength.

 ◆Good vibration fatigue resistance performance 

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

 ◆Uniform voltage distribution 

Because of the large dielectric constant of glass, the double-umbrella disk suspension type glass insulator has a larger main capacitance and the distribution of the voltage is more uniform, thus reducing the radio interference, reducing the corona loss, prolonging the life of the glass insulator and increasing the flashover voltage of the glass insulator.
