S9 transformer

Low no-load loss Low noise and environmental protection Long service lifetime and safe and reliable performance

Product features
1.Energy saving
In comparison with old type of S7,the average no-load power loss of S9 decreases 10.25%,the no-load currentr decreases 37.9%,and the average operation cost decreases 18.9% than the old type.
2.Long service time
Transformer oil tank is fully sealed.The oil tank and its edge shall be connected by bolts or welded.The transformer oils never touch with air,so it can extend service time.
3.High reliability
Some sealing parts of transformer oil tank have been improved and a higher process has been applied in sealing,so reliability should be guanranteed.
4.Small area occupied
A kind of corrugated-plate radiator applied in S9-M transformers,through thermal-expansion and shrinking of the corrugated plate while oil temperature changes,it could be used instead if oil storage box.The shape of corrugated plate radiators is beautiful and occupies a small area.
