Gw1 - 12 Series Outdoor Disconnector Disconnecting Isolator Isolating Isolation Knife Switch Disconnectors

Photos of ProductGeneralGW1-12 series outdoor high voltage AC disconnector (hereinafter referred to as "disconnector") It is applicable to the device on the outdoor high-voltage distribution equipment line for the replacement of 10kV line under voltage and no load, and for the electrical isolation of the overhauled high-voltage bus, circuit breaker and other electrical equipment from the live high-voltage line. It can also be used to close a small capacitive current and inductive current.The Isolation switch(disconnector) is a double column vertical opening type, equipped with a manual or electric mechanism, which can realize three-phase linkage.The Isolation switch meets the technical standards of high voltage AC disconnectors and earthing switches (GB/T 1985-2014) and high voltage AC disconnectors and earthing switches (DL/T 486-2010).Model And MeaningUsage Environmental ConditionsAltitude: no more than 1000m. If the altitude is higher than 1000m, the rated insulation level shall be corrected accordingly.Ambient temperature: upper limit + 45 0C, lower limit - 40 0C, average temperature of the hottest month 30 0C, maximum daily temperature difference 25K.Solar radiation intensity (outdoor): 0.1W/cm2Wind speed / pressure (outdoor): 34m/s  /  700PaPollution level: e-level Icing thickness: not more than 20mmHumidity: average daily relative humidity, not more than 95%, average monthly relative humidity not more than 80%Earthquake resistance: horizontal acceleration 0.3m/2, vertical acceleration 0.15m/s2Safety factor: sinusoidal resonance three cycle wave, safety factor above 1.67.Main AdvantagesThe utility model has the advantages of simple structure, beautiful appearance, and convenient installation.The insulator is designed with high-strength porcelain material and a large climbing distance, which has strong pollution resistance and environmental adaptability and can meet the operation requirements in high-altitude areas.The interlocking device can effectively prevent the misoperation of the grounding knife.The operation is simple and reliable. Manual or electric operation mechanisms can be selected according to the user's requirements.Technical Parameters  No.ItemUnitData1Rated FrequencyHz502Rated VoltagekV123Rated CurrentA630(1250)4Rated Short-time Withstand Current and DurationIsolation SwitchkA/s20/425/425/431.5/4Earthing Switch20/225/225/231.5/25Rated peak withstand currentkA50(63)6Rated short-time power frequency withstand voltageInterphase, to earth(dry)kV/min42/1Fracture(dry)48/1Interphase, to earth(wet)42/17Rated lightning impulse withstand voltageInterphase, to earthkV75Fracture 858Circuit resistanceμΩ≤100≤809Mechanical lifeTimes300010Creepage distancemm≥372 (e - Level)Note: If the altitude is over 1000m, the rated insulation level should be modified as appropriate.   Outline And Installation Dimension   /* 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
