Outdoor Pole Mount Type Sf6 Gas Insulated Load Break Switch

++++GeneralPGS type pole-install load switch was used in 12kV,24kV,33kV rated voltage, rated current 400/630A; 50/60HZ with the load current; over load current of power line open circuit and opening and closing electric systems.The switch can equiped with a conttoller with most advanced technical parameter.PGS-A type PGS is manaully LBS for choice.PGS-M type PGS is a intelligent type LBS for choice. It can automatically disconnect when the distribution line was break down. It could operated by handle; Implementt electro motion and distant. The electric controller was installed in stainless steel cabinet. So it could use in any conditions.++++Service environment  Air temperature:Maximum temperature: +40ºC; Minimum temperature:-20ºCHumidity:Monthly average humidity 95%; Daily average humidity 90% .Altitude above sea level:Maximum installation altitude: 2500mAmbient air not apparently polluted by corrosive and flammable gas, vapor etc.No frequent violent shake++++Feature  SF6 gas insulated : SF6 is a electric insulating gas of non-poison and nonflammable, and have a good arc suppression feature.Bushing diversity: Except for standard porcelain bushing, there are also provide various rubber bushing.Visible open circuit and opening and closing situation: It is easy to see the color sign of the main contact place indicator ( green open circuit; red closing). The indicator and main conductor always keep on direct connecting, make sure show the conductor state.Fast operation: Used by spring stored energy operation system., make sure fast switch on and switch off operate ( no more than 1 second)Could  provide  controller:  Stocked by  electric controller,  could  operated  in  ground  or operate by the main controller through RTU screenSolidity switch: Switch was made by solidity and anticorrosion material, make sure have a long useful life (30 years) have the pole equipment feature.Standard: it will filled full SF6 before delivery, and deal with seal. Test by IEC60265; GB3804.  ++++ Main technical specifications   NoItemUnitData 1Rated voltagekV12/20/332Rated current Hz50/603Rated insulation level(with SF6 gas 0.07Mpa)lightning impulse voltage kV75/125/170Power frequency impulse voltage kV42/50/705Rated current A6306Rated open circuit load current(0.07Mpa//20ºC/h) A6307Open circuit current under 0 pressure A6308Rate peak value withstand current kA509Rated short-time closing current kA5010Rated short-time withstand current kA/s20/111Rated electric cable charge open circuit current A2512Rated wire charge open circuit current A1613Rated closed loop open circuit current A63014Excitation current A2115Rated current open circuit times≥400 times16Rated working pressure MPa0.0717Each operating voltage and resistance μΩ≤15018Gas relative leakage rate year≤1%19SF6 gas moisture contentLeave factory relative figure ppm≤150Switch working figure ppm≤30020Machine stable operation times600021Rated operating voltage and assistant loop rated voltage VDC220;110AC 220;11022WeightM type kg115A type 135  /* 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
