10KV Series Non Encapsulated Coil Dry-Type Transformer

Yuebian Electric Co.,Ltd is one of the leading China 10kv series non encapsulated coil dry-type transformer manufacturers and suppliers, welcome to check 10kv series non encapsulated coil dry-type transformer price with us.SG(C)10 series 10kv uncoated winding grade c insulation dry-type transformerProduct FeaturesSafe, Reliable, Environmentally FriendlyLow noise, Easy MaintenanceOverload, High TemperatureBoard Lowered, The High Level Of InsulationGeneral descriptionSG(C)10 series grade C insulated unsealed coil dry type transformer, which is exploited firstly by our company, is a new kind transformer with the advantages of low loss, high efficiency, safety and environmental protection according to the demand of Chinese power market, the limit of using location and regular over-load of transformer. It combined the techniques of Mora in Germany and Dupont in American SG(C) 10 filed the blank of national dry type transformer market and has obtained the national patent already.(patent No:20042002633.8)The transformer has following characteristic:Grade C insulation (higher than grade H), has good heat emission, big overload capacity, which can work without wind machine for long time under 130% overload, and be full load with out compulsive wind cool without capacity descending (descendance) under IP45 condition.Prefect safe and resistance to fire operating can be combusting for long period under 800℃ and without smoke.Strong resistance to thermal shock.(can be full load immedately at -50℃)Complete waterproof and airproof.No partial discharge.Good hydrophobility and good resistance to alkaline cauterization and fundal influence.Environmental protection: low noise, no deleterious gas, easy to decompositon. It applies to high fireproofing, load fluctuating, unven-tilated, incommodious, dirty and moist environment such as power plant field, subway, metallurgy, hospital, high-rise building, shopping center, crowded resident zone, and the special environment such as petro land chemical industry, nuclear power station, unclear submarine.Applied to fire high, poor ventilation, field is narrow, load fluctuation and dirty wet environment. Power plant such as airport, subway, metallurgy and electric power operation, hospital, high building, shopping centres, residential area and petrochemical, nuclear power plant, nuclear submarines in special environment.Product characteristicsService conditionAmbient temperature: Highest air temperature +40℃, Lowest air temperature -5℃,hottest monthly average temperature +30℃, hottest yearly average temperature +20℃The height above the sea level is below 1000m;The power supply voltage’s cave is similar to sine waveThree-phase power supply voltage is approximately symmetricalInstallation without evidence filth.Service indoor.Iron coreThe iron core is accumulated installed by imported excellent cold rolled silicon steel with high magnetizing with five stepper, the accumulated installation is 45t, and complete blique frame, it can effectively reduce the haysteresis caused by harmonic, non-loaded current, and noise.The surface of iron core is special processed. It can reduce the noise of the transformer and avoid the rustiness and cauterization.The iron core is tightened by the binding screw and the upper and lower clamp is connected with pedestal by draw board. The winding, core and clamp is fixed by stretch gasket and the buffer framework can reduce winding’s virbration and the noise.HV LV windingThe HV, LV winding adopt Grade C glass winding obtained patent based on the technique of Mora in Germany and Dupont in American and immersed international advanced Grade C dipping lacquer without impregnant by VPI vacuum pressure equipment. With many baking and solidify by high temperature, it has strong resistance to short circuit and over load. Adopted the imported copper foil, the big capacity low voltage coil has no ampere-tum unbalance and axial winding helical angle and gets small axial pressure under short circuit. Mean while, for its thin insulation and multilayer ventilation, the radiation can be solved easily. The HV coil adoped the successive framework, it avoids the high voltage, bad radiation capacity, easy to be breakdown, and bad mechanical intensity caused by multilayer circular coil and improves the product’s reliability of it has perfect resistance to humidity and impulse and has no crack, no partial discharge, and easy to decomposition.Overheating protectionThe SG(C) 10 series transformer of 315 kva and upwards all equipped with a set of temperature display protection device avoid the coil overheated. The device adopted the inductive temperature component burying in the low voltage winding as signal source of the digital display. When the temperature has been changed in the low voltage winding, the inductive temperature will display a new temperature value, and effects the control and alarm function according the value to protect the transformer. Outline dimension drawingNote: 1.For HV lead terminal Md, while capacity SN<1600kva, Md=M12;while SN≥1600KVA,Md=M16.2.The transformer has no trolley, if needed, the height should raise 100mm3.The size of forced air cooling system(blower) should not exceed machine(axb).
