Brief introduction of   zinc oxide surge arrester/ lighting arrester

 

Using the  lightning arrester to prevent the shunt capacitor from overvoltage is one of the most efficient and reliable measures, and in many cased it is a necessity.

 

 

lightning arrester  is the most advanced voltage protect equipment nowadays in the whole world. 

Cause of the core parts are made of zinc oxide and many other metal oxide, comparing with traditional arresters, the volt-ampere characteristics of resistor disc have been improved much, meantime the through-current capacity have been improved too, thus the zinc oxide arrester brought fundamental change of arresters.

 

 Application of   zinc oxide surge arrester/ lighting arrester

Zinc Oxide Arrester will protect the power equipment in power system from damage of atmospheric overvoltage and switching overvoltage

 

 

Working condition:

 

1. Environment temperature: -40--+40 degree

2. sea level elevation:<1000m

3. 48HZ<supply frequency<62HZ

4. Power frequency voltage should not be more than continuous running voltage

5. Max wind speed should be less than 35m/s

6. Earthquake intensity should be less than 7 degree

7. If used in contamination area, should be noted in advance.
