  • 1. Low noise: compact designed structure, application of new materials and new processes, noise reduction, no oil conservator, height lower than that of like products. Oil change is not required within the normal life span, 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 that can lead to insulation performance decline (insulation and oil aging). Therefore, regular oil sample test is not necessary.

    3. Reliable Long Service Life Span: the bolted connection or welded 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 span.

    4. Small Size and Artistic Outline. The corrugated plate radiating fin is adopted for S11 series carburetor. In case of any change in the oil temperature, changes in the oil volume shall be adjusted through elastic expansion and contraction of the corrugated plate for compensation. The corrugated tank has an artistic outline, small size and small space occupying.

    5. No Lifting Center: it is not required to check the lifting center before operation of the fully-sealed transformer, thus users can save the expense for lifting center inspection.

    6. Maintenance-free: maintenance is not required.


  • 1. Maximum temperature: +40℃/+104ºF;

    2. Maximum daily average temperature: +30℃/+86ºF;

    3. Maximum annual average temperature: +20℃/+68ºF;

    4. Minimum temperature: -45℃/-49ºF;

    5. Elevation shall not exceed 1000m;

    6. Indoor or outdoor use.

    Note: please make specific instructions in case of any special use conditions.
