Main Principle:

* ZnO lighting arrester is one kind most world advaned over-voltage protector at present.Due to its core components of resistance applying ZnO and other metal oxide to make of comparing with traditional craborundum    arrester.it improves greatly V-A characteristics of resistance,increases the getting trough ability of  resistance,there by it brings fundamental change to features of arrester. 

* Under normal working vlotage,the current passing arrester only A class,when bearing over voltage ,the    excellent nonlinear V-A features of arrester would make effect,the current passing through the arrester  increase high to shousands of ampere instant,the arrester is under getting through state to release over-  voltage enrgy,there for it effective limits the damage to power transmission equipments due to over voltage.

Usage& feature:

   ZnO Lighting Arrester is one kind protecting equipment preventing electric equipments in AC power system from  high voltage and over-voltage operation.

Using Environments:

* Ambient temperature no higher than +40℃,no less than -40℃;

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

* Power frequency not less than 48HZ and no higher than 62HZ;

* Continuous power frequency voltage loaded on lightning arrester no higher than continuous working voltage of lightning arrester;

* Utmost wind volocity no higher than 35m/s;

* Area where earthquake intensity less than 7 degree;

* Messy area should be indicated;

  Our make product voltage range:0.22kV ~110kV.
