10kV oil immersed transformer
Reliable structure 1.Spiral coil with longitudinal oil passage for better internal heat dissipation; 2.Improved the effective support of the coil end face,with stronger resistance to short-circuit current; 3.New lifting and positioning structures have been adopted to ensure greater reliability during long-distance transportation and operation; 4.We have many unique and reliable structures to serve you; 5.Choosing transformers with higher performance levels will result in higher levels of technological content. Excellent materials Choose oxygen free copper wire with lower resistivity and undergo a series of additional surface treatments to make it smoother,without burrs or sharp corners,resulting in lower load loss and more reliable electrical performance of the transformer. Select high-quality silicon steel sheets,and with the improvement of performance level,use silicon steel sheets with lower unit loss to reduce the no-load loss of transformers. Select high-quality laminated wood insulation components that will never crack,even under the action of short-circuit current,and remain intact. Using transformer oil that has undergone deep filtration results in lower levels of water,gas,and impurities,making transformer operation more reliable. Select excellent rubber sealing materials to effectively prevent aging and eliminate leakage. All raw materials undergo quality inspection,effectively preventing aging and eliminating leakage. All raw materials undergo quality inspection,and all raw material manufacturers undergo strict review in accordance with the national standard ISO9000. Good technical and economic performance On the basis of the S9 series,the S11 series products have reduced the average no-load loss by 30%;The no-load current decreases by 70-85%compared to S9;The average temperature rise is reduced by 10K,and the product's service life is more than doubled.Even under overload conditions of 20%,it can still operate for a long time;The average noise reduction during product operation is 2-4 decibels. Fully sealed The M in S11(M)R indicates that the oil tank adopts a fully sealed structure.Compared with ordinary oil immersed transformers,fully sealed distribution transformers eliminate oil storage tanks and replace oil pipes with wave fins as cooling and heat dissipation components.The wave fins of the oil tank are manufactured from high-quality cold-rolled thin plates on a dedicated production line.The wave fins can expand and contract the volume of transformer oil,thereby isolating the transformer from the atmosphere,preventing and slowing down oil degradation and insulation moisture,enhancing operational reliability,and maintenance free normal operation. The surface of the corrugated oil tank is treated with degreasing,rust removal,and phosphating before being coated with a three proof paint,which is suitable for use in metallurgical,petrochemical,mining,and other environments.
