S11 Fully Sealed Oil Immersed Distribution Transformer

Product OverviewS11/S13 series oil immersed distribution transformers use insulating oil as cooling and insulating medium. The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor. Vacuum oil injection process is adopted to effectively prevent oxygen and water from penetrating into transformer oilresulting in the decline of insulating oil performance. It is a new generation of energy-saving and environmental protection products.Maun TeachTypeRatedvoltage(kV)Winding connection modeLoss(W)Short-circuit impendance(%)No-load current(%)Weight(kg)Outline dimension(mm)Gauge(mm)No-loadload(75ºC)LWHS11-M-30/106,6.3,10,10.5,11/0.4Yyn0 or Dyn1110063041.5355750500890 S11-M-50/101309101.3420760520900 S11-M-63/1015010901.2480780550920 S11-M-80/1018013101.2510800710940 S11-M-100/1020015801.1600830720980 S11-M-125/1024018901.169010707301020 S11-M-160/102802310178010707401070400*550S11-M-200/103402730195011607501160 S11-M-250/1040032000.9110011907701210 S11-M-315/1048038300.9135012608301260 S11-M-400/1057045200.8145013208801260550*550S11-M-500/1068054100.8167014009301330 S11-M-630/1081062004.50.6205015309601470 S11-M-800/1098075000.62450160011101470660*660S11-M-1000/101150103000.63000182011001580 S11-M-1250/101360120000.53300193012001670 S11-M-1600/101640145000.54050202012401770 S11-M-2000/1019401830050.44910210012701870820*820S11-M-2500/102290212000.46570235013902080820*1070 Product features1. Choose high-quality grain oriented cold-rolled silicon steel sheet with high magnetic conductivity, 45°fully inclined core jointstep-by-step lamination, which can effectively reduce no-load loss and noise. 2.Fully sealed vacuum oil injection is adopted to effectively prevent the infiltration of oxygen and moisture, and the insulation performance of the transformer is greatly strengthened.3. The fully sealed structure can delay the aging of transformer oil and insulating paper. It not only has compact structure, but also has the advantages of high operation efficiency and maintenance free.  Scope of ApplicationOil immersed transformer has high adaptability to various environments. It is suitable for power system,industrial and mining enterprises and other units. It can be installed indoors or outdoors.Company ProfileGuangdong Haocheng Electric Co.,Ltd is one of the pillar enterprises in electrical equipment industry in Guangdong province.
