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 of IEC standard;
Power loss: no-load loss is 30% lower than that of IEC standard;
Reliability: all in-service products have no damages or oil leakage occurred;
Short circuit withstanding: model SFZ11-50000/132 smoothly passed the short-circuit withstanding test of the national transformer quality supervision and inspection center and also passed Holland “KENA” quality control system.
