Factory Direct Low Price 48kv High Voltage Metal Gapless Arrester

 Product Description48kv High Voltage Metal Gapless Lightning ArresterNormal 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. 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.Technical Parameters:DescriptionUnitValue. Rated voltageKV48 Nominal discharge currentKA10 Rated AC system frequencyHz50 / 60 Continuous operating voltage(rms)KV39 1/4μs steep current impulse (crest)KV100 8/20us Lighting impulse residual voltage(crest)KV139 30/60us Swithcing current impulse KV115 Rectangular current withstand 2msA500 4/10us High current impulse withstand(crest)KA100 Leakage/Creepage Distancemm1280/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
