S9-S11 High Voltage Low Loss Outdoor Factory Price Customized Oil-Immersed Power Transformer

  Welcome to our homepage to see more content!Product DescriptionBasic Info.           The fully sealed oil-immersed power transformer developed by LeiCheng Company has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving and reduce pollution. Compared with the ordinary oil-immersed transformer, the fully sealed transformer eliminates the oil reservoir, and the change of the oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated tank. The transformer is isolated from the air to prevent and slow down oil deterioration and insulation aging, enhance operational reliability, and avoid maintenance during normal operation.                   The three-phase oil-immersed transformer applies new type insulation structure and improves the ability of short-circuit resistance.The iron core is made of high-quality cold-rolled silicon-steel plate.High-voltage winding group is made of high quality copper wires and it adopts multilayer cylindrical structure.All fasteners have been processed with special treatment to prevent them from loosening.            The product is stable,reliable,economic, environmental protection.It can be applied to many places such as power plants,transformer substation ,large industrial mining and petrochemical enterprise and so on.      Oil immersed transformer ,use Japanese Toshiba analysis soft ware and our company special calculation and validation procedures to make sure the performance of products. Superior process equipment ,elaborate material selecting and efficient manufacturing make the transformer have small volume,light weight,low loss,low partial discharge,low noise characteristics.    Product Details       1. The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.       2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer.       3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.      4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.      5. This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small.Product Parameters   6.3kv-15kv Distribution TransformerRated capacity kVAHV (KV )HV tapping rangeLV (KV)Connection symbolNO-load loss WLoad loss WNo-load current%306.3kV10.5kV11kV13.2kV13.8kV15kV±2× 2.5%; Or ±5%0.4Dyn11 or Yyn0906602.1501309602.06315011451.98018013701.810020016501.612524019801.516029024201.420033028601.325040033501.231548040101.140057047301.050068056601.063081068200.980098082500.810001150113300.712501350132000.716001630159500.620001950191400.625002340222000.6                                                             10kv-35kv Distribution Transformer  Rated capacity kVAHigh Voltage(kv)Low Voltage(kv)Connection symbolNo-load loss(w)On-load loss(w)No load current(%)               40010kv11kv20kv35kv0.4Ydn11Yyn057043000.45               50068054100.45               630810308000.4               80098075000.4              10001150103000.35              12501360120000.3              160016401450000.6              20001950191400.6              25002340222200.5Mainly Components:     The mainly parts of this transformer include Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.      1. The oil tank is used to soak the windings by placing it in.      2.Comply with IEC standards with CE/ISO certificates.3.4.5.6.7.8.9.10.       3.be easily contacted & enlarge throughout loading so that the temperature of the oil can be increased and decrease.      4.Buchholz relay is used when a conservator tank is used. Because it indicates errors like loss of oil once it goes low, improper flow of oil between the tank & transformer.     5.Breather Unit includes silica gel that absorbs moisture in the oil. It changes its color from blue color to pink color it is not capable to absorb moisture in the oil.     6.The oil indicator indicates the level of the oil within the conservatory unit.    7.The temperature detector monitors the temperature of the oil. If the temperature of the oil increases to a certain level then the transformer will be disconnected from the service.    8. Pressure relief device decreases the pressure within the transformer to avoid an explosion of the transformer.   9.Thermal relay is used as an indicator for the temperature
