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 material and new process, noise reduction, no oil conservator, height lower than that of like products. Oil change is not required within the normal life, which improves safety and reliability of power grid operation.

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

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 improve service life.

4. Small volume and artistic outline. The corrugated plate radiating fin 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 elastic expansion and contraction of the corrugated plate for compensation. The corrugated tank has artistic outline, small volume and small floor area.

5. Lifting center free: the user is not required to check the lifting center before operation of the fully sealed transformer, and the user can save the expense for lifting center inspection.

6. Maintenance-free: maintenance is not required.

Table 1 Performance parameters of amorphous alloy transformer with primary rated voltage of 6kV and 10kV

Table 2 Insulation level

1. Characteristic of ultra-low loss, energy saving and high power consumption efficiency;

2. The characteristics of low energy and ultra-low loss are utilized during manufacturing of the amorphous metal material, which can substantially save power consumption, reduce electricity output of the power plant,reduce CO₂SO₂exhaust emission relatively, and reduce environmental pollution and greenhouse effect, 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, S (B) H15 amorphous alloy transformer made of amorphous iron core has good resistance to harmonic wave;

6. Rapid returns on investment
