6kv 10ka Distribution Type Polymeric Metal-Oxide Surge Arrester Without Gaps

Company Profile * Our StrengthMore 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 Description * Brief instructionZinc-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. Product Parameters* 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 U1mA* SpecificationElectrical characteristicsSpecificationUnitRated voltage of Surge arrreser6kVNominal discharge current510kARated frequency50HzMaximum continuous operating voltage5.1kVSteep current impulse residual voltage22.6kV(Crest)Lightning Impulse residual voltage18kV(Crest)Switching Impulse residual voltage16.8kV(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   Detailed Photos  *  Spare parts detail for Surge arrester  Packaging & Shipping* Carton & Pllets package Workshop* Assembling workshop* Polymer pressing & Testing room* Warehouse for spare parts and finished goods /* 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
