10kV Grade S9 three phase oil immersed power trans

10kV Grade S9 three phase oil immersed power transformer Specification Description:Complying with the national standard on design, our new S9 three-phase oil-immersed transformers have advanced and reasonable insulation structure and solid short-circuit resistance, with good performance that comes up with the international level of similar products. Compared with S7 series, the products enjoy the average drop rate of 10.25%, 37.7% and 22.4% respectively in no-load loss, no-load current and load loss. Our products are designed reasonable in structure and beautiful in appearance. The tank can be designed with plate radiator or tubular radiator as per customers' demand. As a result, our products are the most popular energy-efficient ones in recent years.Main technical data: Capacity(KVA)VoltageconnectionLoss(W)No-load current(%)Impedance Voltage(%)HV(KV)Tap(%)LV(KV)No-loadLoad3066.31010.511±5±2×2.50.4Yyn0Dyn111306002.14501708702.06320010401.98025012501.810029015001.612534018001.516040022001.420048026001.325056030501.231567036501.140080043001.050096051501.0630120062000.94.5800140075000.810001700103000.712501950120000.616002400145000.6Note: The list shows main performance parameters of a three-phase duplex winding off-circuit-tap-changing distribution transformer.
