This kind arrester is used to protect AC electrical equipments of power plant and transformer substation from being damaged by atmosphere over-voltage and operation over-voltage.

 

 

 

Technical  Parameter:

 

 

 

Keystone:

 

The zinc oxide arrester is the most advanced over-voltage protector in the world, due to make the resistor disc of core component mainly adopt zine oxide arrester, compared with the conventional siliconcarbide arrester,  this presciption of the product improves greatly the volt-Ampere charateristics of the resistor disc and increased through-current capability at over-voltage so as to bring a radical changes for the characteristics of the arresters.

 

Normal service conditions:

 

1.The ambient air temperature is no higher than +40 degree. no lower than -40 degree.

2.The altitude above sea level does not exceed 2000m

3.Power frequency 48Hz~62Hz

4.Maximum wind speed does not exceed 35m/s

5.The earthquake intensity does not exceed 7 degrees

6.The voltage that long-time exerted shouldn't exceed its Max MCOV
