Zinc-Oxide Surge Arrester

General

The Zinc Oxide Type Surge Arrester is the latest advanced over－voltage protector for distribution line and power station device. Incorporated with zinc oxide and other metal oxide as the core resistor disc, the volt-ampere characteristics and the through-current capability of the resistor discare improved drastically compared with the conventional SiC type surge arrester.

Under nominal operating voltage, the current through the surge arrester is only about micro-ampere grade. When the surge arrester experiences an over-voltage, the resistor disc with excellent non-linear characteristics will increase the current through the surge arrester to several thousand amperes instantaneously. The surge arrester is in a conducting state and then will release the over-voltage energy to the earth and thereby protects power distribution I transmission device against the impact of over－voltage.

Technical Performance:

Product performance conforms to technical requirements of IEC60099-4, IEEE.C62.11.
