Transformer, 11kv Transformer, 11kv Distribution Transformer

Transformer Product Description:
S11-M series Oil Immersed type Distribution Transformer is applied to power system of three-phase. 50Hz as well as 11KV and bellows. It is the main transformer equipment of medium and small-sized transformer substation, supplies power distribution, power and illumination for the industry and agriculture.

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.
