Message:Main Power Transformer General:The Xiecheng-brand 220kV,Website:http://www.xctransformer.com, 110kV and 66kV low loss Main Power transformers are independently developed based on advanced domestic and foreign technologies. Featured with reliable low partial discharge level, low loss, low noise, high reliability and strong anti-abrupt short circuit capacity, these products are highly appraised among the vast users and experts with their outstanding performance. The fully sealed products without windlass cover sell well all over the nation. Partial discharge level: the apparent discharge magnitude under the voltage of 1.5 times the nominal voltage is less than 80pC;Noise: below 58dB for products of 63MVA and below (AN);Loss: non-load loss ratio is about 30% lower than IEC standard;Reliability: none of the in-service products has experienced damage accidents or oil leakage;Anti-short circuit capacity: SFZ11-50000/132 passed the short circuit bearing capacity test of Holland KEMA and lab of China National Transformer Quality Supervision Testing Center at one time.Coil:High-voltage windings adopt the continuous interleaved structure to improve the distribution characteristics under surge voltage and obtain relatively uniform electric field distribution. The strips and cushion blocks are chamfered to improve the reliability of insulation. There is winding oil guide structure inside the transformer winding, so that each area within the winding can be fully cooled, thus reducing winding temperature rise and winding hot spot temperature rise and extending the insulation service life. Separate regulating windings are set for high-voltage and medium-voltage regulation units, so that the ampere-turn of each winding is relatively balanced and the axial electro-dynamic force can be effectively reduced in case of transformer short circuit, hence improving anti-short circuit capacity of the transformers. The windings adopt "0" margin design radially; the part between the iron core and t......url:http://www.xctransformer.com
