Zinc-Oxide composite silicone rubber polymer surge lightning 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.
We manufacture a wide range of surge arresters, and we always offer a high performance of lightning surge arrester in China because we have almost 15 years of design, manufacturing and exporting experiences. And We have won pretty good feedback.
