Low Loss 500kVA 11kv 0.4kv 0.415kv Oil Immersed Distribution Power Transformer

Three-phase Oil Immersed Distribution Transformer1.FeaturesThe three-phase oil-immersed distribution transformer produced by our company adopts a new insulation structure to improve the short-circuit resistance; the iron core is made of high-quality cold-rolled silicon steel sheets; high-voltage windings are made of high-quality oxygen-free copper wire as the material , and adopts multi-layer cylindrical structure; all sturdy parts adopt special anti-loosening treatment.The product has the characteristics of high efficiency and low loss, can save a lot of power consumption and operating costs, and has significant social benefits. It is a popularized new technology product. 2.Reliable StructureBased on the traditional structure and mature technology, our company has made many improvements, such as:1) Spiral coil with longitudinal oil passage, better internal heat dissipation;2) Improved the effective support of the coil end surface, and the ability to resist short-circuit current is stronger;3) The new hoisting structure and body positioning structure are adopted to ensure more reliable in long-distance transportation and operation;4) We have many unique and reliable structures to serve you;5) Selecting a transformer with a higher performance level will have a higher level of technical content. 3.Excellent Materials1) Oxygen-free copper wire with lower resistivity is selected, and after a series of additional surface treatments, it is smoother and free of burrs and sharp corners, making the load loss of the transformer lower and the electrical performance more reliable.2) Select high-quality silicon steel sheets. With the improvement of performance level, use silicon steel sheets with lower unit loss to make the transformer no-load loss lower.3) Select high-quality laminated wood insulation parts, never crack, even under the action of short-circuit current, the wire will not move.4) Transformer oil after deep filtration is selected. The lower water, gas and impurity levels make the transformer work more reliable.5) Select high-quality rubber sealing materials to effectively prevent aging and prevent leakage.6)  All raw materials have passed the quality inspection, and all raw material manufacturers have undergone strict review in accordance with the national standard ISO9001 ,CCC.4.Technical DataRated Capacity(KVA)Rated VoltageConnection SymbolNo-load Loss(KW)No-load Current(%)75ºC(W)Load-LossShort Circuit Impedance(%)Weight(Kg)Boundary Dimension (mm)Sound power Level(db)  H.V.M.V.L.V.EquipmentL*W*H (KV)(KV)(KV) 3066.31010.511±5%or±2×2.5%0.4Dyn11Yyn0Yzn11800.3630/6004330800*500*85035 501000.24910/870380820*550*85035 631100.231090/1040410835*580*85035 801300.221310/1250430840*600*88036 1001500.211580/1500460860*600*89036 1251700.21890/18005901020*660*88037 1602000.192310/22006501035*660*95038 2002400.182730/26007101040*680*98039 2502900.173200/30508501140*740*101040 3153400.163830/36509701160*760*115042 4004100.164520/430011301230*800*120044 5004800.165410/515013351320*900*120045 630Dyn11Yyn05700.1562004.516301420*920*123046 8007000.15750019501480*1000*133047 10008300.141030022051600*1100*128048 12509700.131200025651655*1135*137549 160011700.121450031001815*1260*145049 200015500.1118300537851920*1305*151050 250018300.12120045702120*1430*157550 /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
