insulator features


Three-umbrella disk suspension-type glass insulator, professional insulator supplier

 ▼High quality arc resistance 

The three-umbrella disk suspension type glass insulator often suffers from lightning arc impact, causing the surface of the glass insulator to burn and peel, and the new surface after burn is still smooth glass.

 ▼Good anti-aging properties 

When the glass is tempered, the compressive stress is formed on the surface. If there is a crack on the surface of the glass, it will also compress the micro crack without expanding it. The electrical strength of glass remains unchanged throughout the operation.

 ▼Excellent electrical performances 

The electrical breakdown strength of glass medium under the standard shock wave is 1350~1700 kV / cm. At home and abroad, a lot of shock waves have been tested steeped by the wave head at home and abroad. The results are atmospheric flashover, and the vitreous body is not broken through. The operation experience also proves that the three-umbrella disk suspension type glass insulator will not be penetrated by the lightning.
