    Product Introduction:

    How does ZnO varistor work? ZnO has good non-linear Volt-Ampere characteristics which flowing current is tiny when working under normal voltage. However, when there's over-voltage, its non-linear Volt-Ampere characteristics takes protection effect on leakage and breaking current, as the resistance will decrease rapidly and leak the energy of over-voltage.

    Normal service conditions:
    · The ambient air temperature is no higher than +40°C, no lower than —40 °C .
    · The altitude above sea level does not exceed 1000m. ( the plateau area should be indicated when order.)
    · AC system frequency is 50Hz or 60Hz.
    · Industrial frequency voltage brought to bear on arrester for a long time does not exceed the continuous operation voltage of the arrester.
    · Maximum wind speed does not exceed 35m/s.
    · Te earthquake intensity does not exceed 7 degrees.
    · The filthy area should be given clear indication.
