insulator features

 


glass insulator


1、Good mechanical strength

The stability and dispersion of glass are better and the electromechanical strength of stain resistant disc suspended glass insulator decreases after high frequency vibration.

2、Smaller size and weight

Because of the high tensile strength of the mandrel,  composite insulators can be made very lightweight.

3、Good arc resistance performance

The surface of 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.

4、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 insulators 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.
