The zinc oxide arrester is the most advanced over-voltage protector in the world,Due to make the risistor disc of core componet mainly adopt zine oxide arrester. Compared with the conventional silicon carbide arrester,this presciption of the product improves gr-eatly the volt-Ampere characterisics of the resistor disc and increased through-current capability at over-voltage so as to dring a rad-ical changes for the characteristics of the arresters. Under the circumstance of normal operating voltage, the current through the arrester is just on microampere degree, When suff-ered from over-voltage,the arrester’s excellent nonlinear characteristics will make the current through the arrester incrase to several thousand amperse,while the arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments against the demage caused by th over-voltage.

Product characteristic

 

1.Small size,Light weight,resistance to impact,no collision damage during transportation,flexible installation,suitable for use inthe switch cabin.2.Special structure,the overall compression molding,no air gap,good sealing performance,moisture-proofand explosion-proof3.Large creepage distance,good hydrophobicity,strong stain resistance,stable performance and reduceoperation maintenance.4.Unique formula of zinc oxide varistor, small leakage current,slow aging,long service life.

5.With DC reference voltage,rectangular flow capacity and high current and large current withstand capacity are higher than standard requirement.
