Product Description

Product Description
48KV 10KA Polymeric Metal Oxide Gapless Lightning Arrester

Feature: 

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 conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through- current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.

Normal service conditions: 

  1.The ambient temperature: -40°C ~+40°C

 2.The altitude above sea level :not exceed 1000-2000m (the altiplano area should be indicated when order)

 3.Earthquake intensity: not higher than 7 degrees;

 4.Maximum wind velocity :less than 35m/s.

 5.The filthy area should be given clear indication.
