Product Information lightning arrester
The zinc oxide surge arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage.
The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the traditional silicon-carbide arrester, this prescription of the product improves greatly the volt-Ampere characteristics of the resistor discand increase through-current capability at over-voltage so as to bring a radical-change for the characteristics of the arrester.Under the circumstance of normal operating voltage, the current through the arrester is just on microampere degree, When suffered from over-voltage, the arrester's excellent nonlinear characteristics will make the current through the arrester increase to several thousand amperes, while the arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments against the damage caused by the over-voltage
1. Small size, Light weight, resistance to impact, no collision damage during transportation, flexible installation, suitable for use in the switch cabin.
2. Special structure, the overall compression molding, no air gap, good sealing performance, moisture-proof and explosion-proof
3. Large creepage distance, good hydrophobicity, strong stains resistance, stable performance and reduce operation maintenance.
4. Unique formula of zinc oxide varistor, small leakage current, long service life.
5. With DC reference voltage, rectangular flow capacity and high current and large current withstand capacity are higher than standard requirement.
