Metal-Oxide lighting 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 trough ability of resistance.

thereby it brings fundamental under normal 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,therefor it effective limits the damage to power transmission equipment due to over voltage.

a. Ambient temperature no higher than +40℃,no less than -40℃

b. Above sea level no higher than 1000m(order should be indicated if used in tableland area)

c.Power frequency not less than 48Hz and no higher than 62Hz

d.Continuous power frequency voltage loaded on lighting arrester no higher than continuous working voltage of lighting arrester

e.Utmost wind velocity no higher than 35m/s
