ZnO Lightning Arrester Series
Main principle
ZnOlightning arrester is one kind most world advanced over-voltage protector at present. Due to its core components of resistance applying ZnO and other metal oxide to make of, comparing with traditional carborundum arrester. It improves greatly V-A characteristics of Resistance, increases the getting through ability of resistance, thereby it brings fundamental change to features or arrester.
Undernormal working voltage, the current passing arrester only A class, when bearing over voltage, the excellent non-linear V-A features of arrester would make effect, the current passing through the arrester increase high to thousands of Ampere instant, the arrester is under getting through state, to release over-voltage energy, therefore it effective limits the damage to power transmission equipments due to over voltage.
Using environments
Ambient temperature range﹣40℃~﹢40℃;
Above sea level no higher than 1000m (order should be indicated if use in tableland area);
Power frequency is 48-62Hz;
Continuous power frequency voltage on the lightning arrester no higher than continuous working voltage or lightning arrester;
Utmost wind velocity no higher than 35m/s;
Area where earthquake intensity less than 7 degree;
Messy area should be indicated;
Technical performance
Product performance conforms to National standard technical requirements of GB1 1032-2000 (equal to IEC60099-4).
