1.General description
    Embedded pole uses the insulation material to reliably sealing combine vacuum interrupter and the main loop conductive element, and the insulation support as a whole, which has the advantages of simple assembly, stable weight, high reliability and strong environmental pollution tolerance.
    Matched with relevant indoor&outdoor vacuum circuit breaker or vacuum distribution device, it is especially useful to frequent operation places, such as electric power, machinery, chemical industry, metallurgy, mining and other departments, with frequency 50Hz/60Hz, rated voltage 12kV, 17.5kV, 24kV, 27.5kV, 40.5kV.
    Meets or exceeds the requirement of IEC60694 and JB-T11203-2011.
