High Voltage Oil Immersed Distribution Transformers, Manufacturer of Power Supply, 10kv Oil Power Transformer

  High Voltage Oil Immersed Distribution Transformers, Manufacturer of power supply, 10kv Oil Power TransformersHigh Voltage Oil Immersed Distribution Transformers, Manufacturer of power supply, 10kv Oil Power TransformersOil immersed distribution transformerFeaturesThe three-phase oil -immersed distribution transformer applies new type insulating structure. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multi-layer drum type structure. All fasteners have been processed with special treatment to prevent them from loosening. As high-tech product that promoted by the country, the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.Advantage of structureWe employ spiral coil with longitudinal oil path to make a better interior cooling effect;We improve the effective support of the coil's terminal surface to strengthen the anti-short circuit current capability.We employ new hoisting structure and body-positioning frames to guarantee that the long distance transport and movement will be more reliable;Canceled the oil tank, the wave wings of tank instead of the tubing as a cooling device, corrugated tank is made of high quality cold press sheet on dedicated machine and enhance the reliability of running.S11-M Type 6~10 kV Performance parameters Rated capacity(KVA)Voltage Combination and  tap  rangeconnection of transformer windingNo-load loss(W)Load loss (W)No-load current (%)Short circuit impedance (%)High voltage(KV)High voltage tap range( %)Low voltage(KV)30506380100125160200250315400500630800100012501600200025001110.5106.36±5%±2x2.5% 0.40.69Yyn0Dyn11 10013015018020024028034040048057068081096011501360164019602310630/600910/8701090/10401310/12501580/15001890/18002310/22002730/26003200/30503830/36504520/43005410/51506200750010300120001450019800230002.32.01.91.91.81.71.61.51.41.41.31.21.11.01.00.90.80.80.74444444444444.54.54.54.54.555Improved from S9 series product, S11 series product reduces the no-load loss by 30%, no-load electric current by 70~85%, average temperature by 10K, noise level by2~4db, and double the products service life. Even under 20% overloads, it can also work for long period of time.S11-M Type 20kVPerformance parameters Rated capacity(KVA)Voltage Combination and  tap  rangeconnection of transformer windingNo-load loss(W)Load loss (W)No-load current (%)Short circuit impedance (%)High voltage(KV)High voltage taps range (%)Low voltage(KV)50100125160200250315400500630800100012501600202224±5%±2x2.5% 0.4 Yyn0Dyn0 210290340360430510610730860104012301440176021201270/12102120/20202500/23802970/28303500/33304160/39605010/47706050/57607280/6930828099001215014670175502.001.801.701.601.501.401.401.301.201.101.001.000.900.806.56.56.56.56.56.56.56.56.56.56.56.56.56.5S13 transformer significant energy saving, uniform magnetic circuit, low no-load loss, low noise, low temperature rise, high efficiency, significant energy saving effect of distribution transformers. Using the new core material, and uniform distribution of the magnetic circuit, greatly reduces the load excitation current and no-load loss. As the core of the oblique three -seam construction, so reliable operation, small size, light weight, and available for residential areas, commercial street, industrial and mining enterprises and rural Power and lighting purposes. Energy conservation. Compared with the original S11, the average no-load loss reduced by 20% or more, the no-load current is reduced by 25% or more, operating costs dropped by an average of more than 15%.Long service life, transformer core with new core material, and greatly reduce the loss significantly extending the life of the transformer.Small footprint, the core is made from high quality cold rolled grain oriented silicon steel sheet; high, low voltage winding made of high quality oxygen-free copper wire and multilayer tact process structure; All fasteners are used special relax treatment, the high mechanical strength, and transformer sizes small, light weight, and the fully sealed tank, can be widely used in various environments.
