The S11 series is a three-phase oil immersed distribution transformer. The iron core material shall be cold-rolled silicon steel
sheets such as DQ133 (Type 9), 30ZH120 (Type 11), 23ZH90 (Type 13), etc. The iron core material used in actual production shall
not be lower than the requirements of the drawings.
The S11 and 10KV low loss power transformers adopt a fully sealed corrugated oil tank structure, and the transformer oil does not
come into contact with the surrounding air. Therefore, the transformer oil will not absorb external moisture, thereby not reducing
the insulation strength; In addition, due to the inability of oxygen to enter the fuel tank, the aging of insulation materials is
avoided, which improves the service life of the product and also improves social benefits.
Product model
Good technical and economic performance: On the basis of the S9 series, the S11 product has an average reduction of 30% in no-load
losses and a decrease of 70-85% in no-load current compared to the S9 series.
Long service life: The transformer oil tank adopts a fully sealed structure, and the oil tank can be bolted or welded to the edge
of the tank. The transformer oil does not come into contact with air, extending its service life.
High operational reliability: The sealing components of the fuel tank have been improved to increase reliability and improve the
level of technology to ensure the reliability of the sealing.
Small footprint: The S11-M series power transformer oil tank adopts a corrugated plate radiator. When the oil temperature changes,
the corrugated plate can replace the role of the oil storage tank due to thermal expansion and contraction. The corrugated plate
oil tank has a beautiful appearance and a small footprint.
