Daelim brand 220kV, 110kV and 66kV low-loss series transformer is our independently developed new generation of transformers on the basis of absorption of domestic and foreign advanced technology, which features low local discharge, low loss, low noise, high reliability, strong protection against abrupt short circuit. Its excellent performance has been recognized by wide users and highly appraised by experts. The full-sealed suspending-cover free products sell well nationwide.
Amount of local discharge: The apparent discharge amount under 1.5 times of rated voltage is less than 80pC;
Noise: Products of 63MVA and below is lower than 58dB(AN);
Power loss: No-load loss is 30% lower than that of IEC standart;
Reliability: All in-service products have no damages or oil leakage occurred;
Short circuit withstanding: Model SFZ11-50000/132 smoothly passed the short-curcuit withstanding test of the national transformer quality supervision and inspection center and also passed Holland "KEMA" quality control system.
The coil adopts an interleaved-continuous structure to improve the voltage characteristic under impact voltage and make volatege evenly distributed. In the windings there are zigzag oil guide structures to fully cool all areas by lowering the temperature rise of the windings and hot points of the windings, therefore prolonguing the insulation service life.
The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm.
