oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding
Advantage:
1, low no-load loss and low load loss;
2, low noise;
3, low voltage partial discharge;
4, high anti short-circuit capacity;
5, reliable performance, no oil leakage and no damages.
Compare with S9 series Transformer, S11-M series Transformer decrease 30% of no-load loss; decrease
70-85% of no-load current; decrease 10K of average temperature rising; double the service life; decrease
the noise of 2-4db; decrease 40 % of running cost.
Normal S11-M Series Transformer apply to the altitude below 1000m; the circumstance temperature between
-25ºC and +40ºC.
