Zno Metal Oxide Varistor of Surge Arrester MOV of MOA Accessories of Lightning Arrester

ZnO metal oxide varistor is the core element of MOA. Zno varistor is mainly made from Zinc Oxide. Gapless zinc oxide (ZnO) surge arresters are widely used between the phase and ground terminals in the power system.

Why is ZnO used in lightning arresters?

A Lightning arrester is a kind of equipment to protect the machine against the overvoltage impulse. Compared with traditional carborundum, MOV(Metal Oxide Varistor) has greatly mended voltage-current characteristics and improved through-current capability, thereby it will line up protection. According to the surge arrester selection guide, the Gapless zinc oxide surge arrester will use a ZnO metal oxide varistor. Valve-type metal oxide surge arrester will use Sic metal varistor.
