|Product Model:||Metal Oxide Varistor||Use:||Surge Arrester|
zinc oxide varistor,
high voltage varistor
Lower Voltage Zno Resistor Disc , Metal Oxide Varistor Disc D31
Excellent non-linear characteristics
Full face metalized electrodes.
Zinc oxide varistor is the core of the arrester,which main component is Zinc Oxide and with a small quantity of bismuth oxide, fluoride oxide, manganous carbonate, antimony oxide and other gleam of additive and made with high temperature.
Zinc Oxide Varistor is widely used in large filed of lightening protection,they are
specified according to the voltage range that they can tolerate without damage.
Other important parameters are the varistor's energy rating in joules, operating
voltage, response time, maximum current, and breakdown (clamping) voltage.
Energy rating is often defined using standardized transients such as 8/20
microseconds or 10/1000 microseconds, where 8 microseconds is the transient's
front time and 20 microseconds is the time to half value.
Large 2000μs rectangular impulse absorption capacity.
