Product Description

Zinc oxide arrester is the most advanced over-voltage protector internationally. For that its core component*-resistance slice adopts the material including zinc oxide and many kinds of metal oxides, compared with traditional silicon-carbide arrester, its volt-ampere characteristic of resistance slice has been improved to great degree, as well as the current-transmit ability of resistance slice, as a result, the capability of arrester has been improved basically and thoroughly. When arrester is under normal work voltage, the current crossing arrester just is microampere rank; Provided suffered by over-voltage, the nonlinear volt-ampere characteristic of arrester will work to great extent, the current crossing arrester will increase to thousands of ampere immediately, that is, the arrester is under transmission case and will discharge voltage energy so as to limit damage of power-distribution and convert equipment from over-voltage efficiently.
