The key elements of Surge arrester

Compare

The varistor is the core element of MOA, which is mainly made by Zinc Oxide. Compared with traditional carborundun, MOV(Metal Oxide Varistor)has greatly mended voltage-current characteristics and improved through-current capability, thereby to line up protection.

Our company produces series of Zno varistors and Sic varistor for polymeric housing surge arresters and porcelain housing surge arresters from 0.22kv to 330kv, and passed ISO9001-2000 International Quality Management System Recognition.
