12kv Surge Arresters with Polymer Housing

Product DescriptionThe 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.Surge arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lighting impulse voltage and operated over-voltage.   Company Profile More than 35 years of production experience;Sample order is available;Coustomerization is available.Continuous improvement and perfection of products;High productivity, large spare parts inventory.    Product ParametersElectrical characteristicsSpecificationUnitRated voltage of Surge arrreser12kVNominal discharge current510kARated frequency50HzMaximum continuous operating voltage10.2kVSteep current impulse residual voltage42.2kV(Crest)Lightning Impulse residual voltage36kV(Crest)Switching Impulse residual voltage31.7kV(Crest)Long duration current impulsewithstand voltage150250AHigh current impulses65100kA (Crest)Rated Short-circuit current20 / 12 / 6 / 0.6 ± 0.2kAClass of Surge arresterClass 1 or Class 2 ApplicationDistribution type With or without gapGapless Designation of arresterDesign B     Spare parts   NEMA A or B mounting bracketwith/without Disconnectorwith/without Earth leadwith/without Bird guard capwith/without Line clampwith/without Upper terminal (incoming line) bolt sizeM12 Lower termina (outgoing line) bolt sizeM10     Material   Upper terminalStainless steel 304 HousingPolymer type Color of housingDark grey / light grey VaristorHigh quality zinc oxide varistor Size of Varistor35mm / 38mm /40mm / 42mm     Package   Qty/package3pc/carton   Service conditions  Environment maximum temperature40ºCPollution levelHeavy Altitude≤1000Meter   StandardIEC60099-4:2014  Normal service conditions1.The ambient temperature: -40°C ~+40°C2.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 :lower than 35m/s.5.The filthy area should be given clear indication. Work Shop  Packaging & Shipping Certifications  /* 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
