High Voltage Dry Type Transformer 3 Phase Step Down Distribution Oil Immersed Power Transformer

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

Technical and 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.
