General

    Widely used in power plant, substation and various monitoring and application environments. 
    Long endurance vacuum interrupter and epoxy casting technology have ensured that no maintenance is required for integrated pole assembly. 
    Adopt APG technology which makes the poles particularly sturdy and reliability and protects the interrupter from effect of the environment. 

   The stucture is more compact and reliable.
