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.
· Te earthquake intensity does not exceed 7 degrees.
