Y10W 12kv Polymer Lightning Surge Arrester 12KV Surge Arrester for Distribution Line

The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc   of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this   prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through-   current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.

    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.
