    Product Overview:
    ZW32-12 Outdoor high-voltage vacuum circuit breaker is outdoor distribution equipment with 12kV rated voltage and 50HZ three phase alternating current It is applied to lead current, over current and short circuit current during the breaking-closing electric system It is suit for protecting and controlling in the transformer substation, industrial and mining establishments' distribution system or other rural power grids.


    Main Feature:

    1.Using the silicone rubber post can reduce the switch's weight, make nice appearance and that isn't easy to fall to pieces
    2.Using the technelogy, the vacuum arcing chamber becomes smaller, environment resistance and no maintenance
    3.As the insulating medium in the product is air, that can avoid the risk of oil and air leakage
    4.Can choose to assemble the spring operating mechanism or permanent magnet mechanism
    5.Can compose the recloser with coincidence controller, and also can compose the sectional~zer with segment controller.

    Main Technical Parameter:

    No.
