110kv power transformer ,oil filled power transformer,mva power transformer
Main functions and characters
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 feature low local discharge, low loss, low noise, high reliability, strange 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 discharged: The apparent discharge amount under the circumstances.5 times of rated voltage is less than 80pCs; Noise: Products of old3MVA and below is lower than 58dB(AN); Power loss: no-load loss is 30% lower than that of IEC standard; Reliability: All in-service product have no damages or oil leakage occurred; Short circuit withstanding: Model SFZ11-60000/132 smoothly passed the short-circuit withstanding test of the national transformer quality supervision and inspection center .
