In case of any change in the external dimensions and weight provided in the instructions due to technical improvement,

the actual product shall prevail.

1. Low Noise: compact design structure, application of new materials and new process, noise reduction, no oil conservator, height lower than that of similar products. Oil change is not required within the normal life, which improves the safety and reliability of power grid operation.

2. Vacuum oil filling process is adopted for transformer sealing, which completely removes the dampness in the transformer oil tank. The transformer is not in contact with air after sealing, which effectively prevents the decline in insulation property (insulation material and oil aging) caused by the oxygen and moisture entering the transformer. Therefore, oil sample test does not need to be conducted regularly.

3. Reliable Long Service Life: the bolted connecting structure is adopted for the fully sealed box cover and box edge, so as to isolate contact between oil and air. Insulation will not be affected with damp, which greatly reduces insulation aging speed and improves service life.

4. Small Size and Artistic Outline. The corrugated plate heat sink is adopted for S (B) H15 series carburetor. In case of any change in the oil temperature, changes in oil volume shall be adjusted through the elastic expansion and contraction of the corrugated plate for compensation. The corrugated tank has an artistic outline, small size and floor area.

5. No Lifting Core Inspection: it is not required to check the lifting core before operation of the fully sealed transformer, and the user can save the expense for lifting core inspection.

6. Maintenance-free: maintenance is not required.

Table 1 Performance Parameters of the Amorphous Alloy Transformer with Primary Rated Voltages of 6kV and 10kV

Table 2 Insulation Level

1. Ultra-low loss, energy saving and high power efficiency;

2. The characteristics of ultra-low loss and low energy are utilized during manufacturing of the amorphous metal material, which can substantially save power consumption, reduce electricity output of the power plant, relatively reduce CO₂ SO₂ emissions, and minimize environmental pollution and greenhouse effect, be maintenance-free and pollution-free;

3. Low operating temperature, slow insulation aging and long service life of the transformer;

4. High overload capability, high mechanical strength;

5. When the amorphous iron core passes through magnetic flux with higher frequency, it still has the characteristics of low iron loss and low exciting current, so as to avoid iron core saturation. Therefore, the S (B) H15 Amorphous Alloy Transformer with amorphous iron core has good resistance to harmonic wave;

6. Rapid returns on investment.

1. The elevation shall not exceed 1,000m

2. Ambient Temperature Maximum Temperature           +40℃/104℉

                     Maximum daily average temperature       +30℃/86℉

                     Maximum annualaverage temperature     +20℃/68℉

                     Minimum temperature                               -30℃/-22℉(applicable for the outdoor transformers)

                     Minimum temperature                               -5℃/23℉(applicable forthe indoortransformers)

3. The waveform of the supply voltage is similar to sine wave

4.The supply voltage connected with the multi-phase transformer shall be approximately symmetrical.
