S type three-phase Oil-immersed Power Transformer

•Introduction The performance of our S9 S10 S11 series 20kV and 35kV three-phase oil-immersed transformer conform to the standard of GB 1094-1996 “Power Transformer “ and GB/T6451-2008 “Technical Parameter and requirements of Three-phase Oil-immersed Power Transformer”. The iron core is made of quality cold –rolled silicon steel sheet , and the coil is made of quality oxygen-free copper, featuring good outlook and safe running . The products are widely used in power transmission and distribution of industrial and agricultural power networks. •Main function and features High reliability, advanced level of performances, reasonable economical indicators. The core joints are of stepped shape with this steps , and the surface of the core is coated with cured paint to lower losses and noises. The winding has novel structure and its oil passage is reasonable designed composition. Its newly designed insulation structure helps enhance its mechanical strength and this short-circuit withstanding ability . The oil tank is in various types , all have good outlook . •Main Technical parameters for 35kV level, S9-,S10-,S11- series distribution transformer Rated power (kVA) High Voltage (kV) H.V Tap range Low Voltage (kV) Connection Symbol Short-Circuit Impedance (%) No-load Loss (W) On-Load Loss (W) No-load Current (%)9 Type10 Type11 Type9 Type10 Type11 Type80035 38.5±5% ±2×2.5%6.3, 6.6, 10, 10.5Yd1112 14125011109809900935093501.051000149013201160122001150011500112501760157013801465013900139000.916002130190016601765016600166000.8520002610232020301935018300183000.7525003150280024502070019600196000.75315073870344030102430023000230000.740004640412036102880027200272000.750005490488042703300031200312000.663007.56570584051103690034900349000.68000YNd119000800070004050038300383000.551000010620944082604770045100451000.551250081260011200108005670053600536000.5160001530013600119006930065500655000.5200001809016100141008370079100791000.5250002151019120167309900093500935000.4315002565022800200001188001122001122000.4 •Weight and Overall dimension Rated power (kVA)Weight (kg)Overall dimension(mm)Gauge (mm)Untanking weightOiltotalLWH800479016504790220011901930820×8201000521017605210235013002000820×82012506080201060802500142021701070×107016006610192066102600160023501070×107020007440216074402730175025501070×107025008240258082402870190027301070×107031509000268085403000210029101070×10704000108002960111803150238031001070×10705000120003050124803280250032501070×10706300131004050159003400267034001475×14758000143204200171303530275035501475×147510000150407480252303600282035701475×147512500170008010270003690320036501475×147516000190008560325003780370037001475×1475200002080010030377703850425037501475×1475250002200012300426004000450038501475×1475315002400013500511004200470039501475×1475
