    GDQC-501H SF6 Vacuumizing and Filling Device hits:

    Product Description

    The model GDQC-501H is mainly used for vacuumizing and vacuum degree testing during installing, running and maintaining procelain SF6 breakers of 35-220kV, CT/PT and other SF6 equipment. It is a compact device, all filling and vacuumizing device is installed on a rugged metal car-frame. It is easy to move even on macadam road.


    Product Configuration

    1. Vacuum pump, 24hours continuous working without heating and losing vacuum degree.

    2. Pointer vacuometer

    3. Regulating valve

    4. Gas pipe

    5. The required valve for SF6 breaker maintenance

    6. Control part



    1. Fast air extracting for SF6 equipment, with good sealing.
    2. High efficient, with fast filling for SF6 equipment.
    3. The mode of gas filling is flexible, air pressure is adjustable.
    4. Customized phase sequence protection, voltage withstand up to 500V, greatly improve the reliability.
    5. Air cooling and movable type. It can be used even in no water condition.
    6. 3phase 5wire power supply, with leakage protector.
    7. Handle moving type, compact and rugged, suitable for working in harsh environment.
    8. Ball valve using Swagelok principle, the sealing components has auto-compensation performance.
    9. Ball valve is applied to vacuum and pressure working condition, ensure the vacuum and pressure is not leakage.
    10. With wheels, easy to move.
    11. Complete function, small size, and less energy dissipation, low noise.
    12. Using digital vacuum vacuometer, with stable performance, vacuum degree is easy to read and the measurement is accurate.
    13. Full automatic oil back protection system.
    14. One set of vacuum pump with 3chambers can be customized.
    15. It is helpful for testing SF6 dew point, purity, decomposition products and leakage/year leakage rate.
