S11-M 3 Phase 11kv 33kv 100-3150kVA Oil Immersed Power Transformer

Model Description




Technical parameters and structure 

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.
