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.
Lightning Arrester Usage & Feature
The Zinc Oxide lighting arrester protects the electrical equipments in AC power systems against being damaged by atmos-pheric over-voltage and operational over-voltage.
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-proof.
3.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.
