220kv 110kv 66kv Oil-Immersed Main Power Transformer

Main Power Transformer General:

20kV, 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.
