Brief instruction
Zinc-Oxide arrester is used for protection of outdoor distribution overhead line, transformer, cable connector and electric equipment from being damaged by lightning Impulse voltage and operated over-voltage.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.Products are completely in accordance with IEC60099-4 standard.
