Performance advantages of double-umbrella disc suspension glass insulator
Good anti-pollution performance: the double umbrella structure makes the pollution distribution on the surface of the insulator more uniform, and it is not easy to form local pollution accumulation, thus improving the pollution-resistant lightning pressure of the insulator, and effectively reducing the occurrence of pollution flashover accidents in areas with serious pollution.High mechanical strength: it can bear the vertical load and horizontal tension of the conductor, as well as the additional load generated by severe weather conditions such as strong wind, rainstorm, ice and snow, etc., to ensure that the insulator will not be damaged by mechanical stress during long-term operation.
Long service life: Due to its good pollution resistance and mechanical strength, double umbrella insulators can be used for a long time under normal operating conditions, reducing the frequency of insulator replacement and reducing line maintenance costs.
