- Warranty Period:3 Months
This series of products are applicable to harsh environment which has strict requirements on safety against fire, big load fluctuation and which is wet and full of dirt such as airports, power plants, metallurgy plants, hospitals, high buildings, shopping centers, densely-populated areas as well as the special circumstances such as petroleum and chemical plants, nuclear power plants and nuclear submarines.
With good heat radiating condition, the transformer has long thermal life and extremely strong ability of overload. Air cooling is not needed under the circumstance of 120% long overload and IP45. The transformer is able to operate with full load in a long term;
With excellent performance of safety and resistance to inflammation, no smoke would emerge under long-time inflammation at 800℃;
Strong resistance to thermal shock (The transformer can be added to full load immediately at 50℃.);
100% water-proof and resistant to moisture;
There is almost no partial discharge due to the special coil structure and field intensity calculation;
The transformer has low load loss and is energy-saving. Compared with SC9 dry-type transformer series, no-load loss of this series reduces by an average of 10% and load loss 5%;
Insulating materials and copper lines can be easily separated and recycled after the transformer’s working life ends so that no pollution will produce.
