10kV S13 three-phase energy-saving oil-immersed  distribution transformerS13 energy-saving distribution transformers are made of high qualtiy magnetic silicon steel, with traditional core lamination process and optimized design. it decreases the no-load loss by 27% in average,currently second only to the latest generation of SBH15 amorphous alloy transformers.It has a high PPR( performance to price ratio).products are used in industrial and mining enterprises. residential quarters. as well as urban and rural power grids and other places.Performance and characteristic of 10KV and S13 type transformer:The S13 type oil immersed transformer is the best performance energy saving product for present laminated core transformer. The S13 type products producing by our company adopt high quality 0.23mm magnetic oriented silicon steel sheet,its HV and LV windings are produced by copper foil and copper wire, and the HV winding is of multilayrered cylinder type, it can balance the distribution of ampere turn of winding with low flux leakage, high mechanical strength and strong capacity of anti-short circuit. The winding and core adopt vacuum drying, the transformer oil adopts vacuum oil filter and vacuum oil filling, it can improve the insulation strength in transformer.typeVoltage combination andtap range(KW)VectorgroupNo-loadloss(KW)On-loadloss(KW)No-load current(％)Short circuit  impedance(％)Trackgauge(mm)HVTaprangeLVS11-M-3066.31010.511±5％或±2x2.5％0.4Yyn0或Dyn110.080.63/0.601.614.0400x400S11-M-500.100.91/0.871.40S11-M-630.111.09/1.041.33S11-M-800.131.31/1.251.33S11-M-1000.151.58/1.251.26S11-M-1250.171.89/1.801.19S11-M-1600.202.31/2.201.12550x550S11-M-2000.242.73/2.601.05S11-M-3500.293.20/3.050.98S11-M-3150.343.83/3.650.98S11-M-4000.414.52/4.300.91660x660S11-M-5000.485.41/5.510.84S11-M-6300.576.200.774.5S11-M-8000.707.500.70660x660S11-M-10000.8310.30.70S11-M-12500.9712.00.63820x820S11-M-16001.1714.50.56(1)For the transformer whose capacity is 500KV and below,the on-load loss value above diagonal line is suitable for Dyn11 connection,and the value below diagonal line is suitable for Yyn0 connection.(2)Overall dimensions are for reference only,and we have a right to change it.(3)We can produce transformers with special performance parameter according to requirements of users.
