Product Description


 

Product Description

24kv Surge Arrester Polymer 5ka 10ka Lightning Arrester
Zinc-Oxide arrester is used for protection of outdoor distribution overhead line, transformer, cable connector and electric equipment from being damaged by lightning Impulse voltage and operated over-voltage.

How does ZnO varistor work? ZnO has good non-linear Volt-Ampere characteristics which flowing current is tiny when working under normal voltage. However, when there's over-voltage, its non-linear Volt-Ampere characteristics takes protection effect on leakage and breaking current, as the resistance will decrease rapidly and leak the energy of over-voltage.

Products are completely in accordance with IEC60099-4 standard.

Our Advantages

1.The low weight facilitates installation and permits erection in limited spaces and at almost all angles.

2.No continuous current and low current impulse residual voltage.

3.Excellent pollution and short circuit performance.

4.Safe to touch when energised by accident.                                                    

5.Stable U-I characteristics,even after multiple strikes.

6.Resistant to UV,ozone,chemicals,mechanical abuse.

7.Fully qualified following IEC60099-4.   

8.Using best material.9.Type test report from KEMA lab
