Factory Direct Sales 9kv Lightning Arrester Insulator

Polymer housed Metal Oxide arrester lightning
Metal-Oxide lighting arrester is one kind most world advanced overvoltage protector at present.Due to it score 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 ablity of resistance,thereby it brings fundamental Under normal working voltage, the current passing arrester only A class,when bearing overvoltage,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 equipment due to overVoltage.

Using Environments:
a) Ambient temperature no higher than+40ºC, no less than-40ºC;
b) Above SeaLevel 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;
f) Area where earthquake intensity less than 7 degree.Messy area should be indicated.
