 Product use:
The performances of model S11-M  series full-sealed oil-immersed distribution transformes conform to Standards IEC. Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality oxygen-free copper.It adopts radiator oil tank of corrugated shteet type or expansion type.
As it doesn't need oil conservator, the height of transformer is reduced, and as the transformer oil doesn't contract with air, the oil ageing is retarded, thus prolonging the service life of transformer.

 

 This product is widely used in urban power grid reconstruction, residential district, factory, high-rise building, mining factory, hotel, shopping mall, airport, railway, oil field, wharf, highway and other outdoor places.Product features:
1. It's an environment-friendly transformer with low no-load loss, no-load current and noise;
2. No oil storage box to save space;
3. Whole sealed with vacuum oil filling, high stability of insulation;
4. Adopts the corrugations on the oil tank as its heat-radiation parts, corrugations can expand or contract accord to the change of oil volume
5. Fully sealed structure, maintenance free;
6. With oil level gauge to ensure the safety running.

 

Applicable Environment:
1.High ambient temperature: +40ºC
2.Low ambient temperature: -25ºC
3.Altitude: <1000m
4.Monthly average relative humidity: 90% (20ºC)
5.Installation location: Install in a place where there is no fire, explosion hazard, serious pollution, chemical corrosion and severe vibration, indoors or outdoors

 

Economic performance:
On the basis of The S9 series, the no-load loss of S11 series products has been reduced by 30% on average.The no-load current decreased by 70-85% compared with S9;The average temperature rise is reduced by 10K, the service life of the product is more than doubled, and the product can run for a long time even under the condition of 20% overload.The operating noise of the product is reduced by 2-4 dB on average.
