9kv Surge Arresters with Polymer Housed

Product DescriptionZinc-Oxide arrester is used for protection of outdoor distribution overhead line, transformer, cable connector and electric equipment from being damaged by lightning Impulse voltage and operated over-voltage.How does ZnO varistor work? ZnO has good non-linear Volt-Ampere characteristics which flowing current is tiny when working under normal voltage. However, when there's over-voltage, its non-linear Volt-Ampere characteristics takes protection effect on leakage and breaking current, as the resistance will decrease rapidly and leak the energy of over-voltage.Products are completely in accordance with IEC60099-4 standard.  Detailed Photos Our AdvantagesMore 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.  Design Highlights√ MOV discsHigh quality MOV discs are made in Zhejiang or Chengde China.√ Upper TerminalsMade of Grade 304 stainless steel√ Sealing performance of arresterDuration of 42 hours into hot water around 100ºC√ 100% routine tested for below test itemsReference voltage at D.C. 1mALeakage current in D.C.0.75 U1mAProduct ParametersElectrical characteristicsSpecificationUnitRated voltage of Surge arrreser9kVNominal discharge current510kARated frequency50HzMaximum continuous operating voltage7.65kVSteep current impulse residual voltage33.7kV(Crest)Lightning Impulse residual voltage27kV(Crest)Switching Impulse residual voltage23.8kV(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 conditions 1.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. Packaging & Shipping FAQQ: How about the performance of your surge arresters?A: We use reliable material from our supplier and each batch material have qulified certificate. And the assemblied product also 100% tested before package.  Q: Can we customize the surge arresters according to our drawing/design?A: Yes, we accept customized order, but the quantity needs to reach at 1000pcs if the mold fee are beared by you. For mold fee beared by us, the quantity need to reach to a large one. Q: What kind of certificate of the surge arrester you have? A: We have KEMA etc.Q: What is MOQ of the surge arrester?A: The MOQ of the surge arrester is 1 piece for sample.Q: What is the warranty for the surge arrester?A: For the all surge arrester, we offer 2 years warranty for free.Q: What is the terms of payment?A: T/T, L/C,western union, trade assurance or cash; 30% for deposit, the balance 70% before shipment.Q: What is the delivery time?A: 3 work days with stock after receiving the payment. No stock, 20 work days after receiving the payment. /* 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
