insulator features


earth wire disk suspension-type glass insulator


 ●Good  mechanical strength 

The stability and dispersion of glass are better, and the electromechanical strength of Earth Wire Disk Suspension Type Glass Insulator decreases after high frequency vibration.


 ●Low spontaneous detonation rate for product annual operation 

The spontaneous detonation of the earth wire disk suspension type glass insulator in line operation pertains to early exposure. It generally happens in the first one to three years(spontaneous detonation peak period), later on shows a tendency to gradually decline and then stabilizes at a certain level, which increases the reliability of safe operation of the line.

 ●Excellent sand-proof and anti-U.V performance 

The toughened internal stress protective layer of the earth wire disk suspension type glass insulator is capable of resisting the sand invasion during desert storms, high surface temperature and ultraviolet radiation.
