9kv 15kv Zinc Oxide Surge Arrester Power Distribution Application GB11032 2000

zinc oxide surge arresters using non-linear V- the Ante excellent oxygen zinc resistance film, and therefore theonly slope 0f the arrester, lightning surge, the protective properties of the operating wave than traditional silicon carbide

arresters have greatly improved. In particular, zinc oxide varistor has only slope response characteristic, without delay to thesteep voltage operation, low residual voltage, there is no discharge dispersion, etc.. Overcome inherent in the silicon carbide

arrester discharge delay due to steep slopes of the steep slope of the discharge voltage operating wave discharge dispersioncaused by the disadvantages of operating wave discharge voltage, making the slope protection under the operating wavemargin is greatly improved. in the insulation co-ordination can be done on steep slopes, lightning surge protection of theoperating wave margin is nearly identical, and thus provide the best protection for electrical equipment, thus improving thereliability Of the protection. The high-voltage surge arresters at the same time absorb the lightning over-voltage, operating
