10kv-220kv Three-Phase Oil-Immersed Power Transformer

Production Description:

The tree-phase Oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayer drum type structure. All fasteners have been processed with special treatment to prevent them from loosening

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.
