S11~S13 series 10kV~35kV low loss non-magnetic voltage regulating transformer features good economic performance.

Based on S9 series, the no-load loss of S11-S13 series products is reduced by 30% on average, and the no-load current is reduced by 70% - 85% compared with S9 series.

Long service life

The transformer oil tank adopts a fully sealed structure. The oil tank can be bolted or welded to the edge of the tank. The transformer oil does not contact with the air, which increases the service life. High operation reliability.

The parts and components related to the oil tank seal have been improved to increase the reliability, and the process level has been increased to ensure the reliability of the seal.

Small floor area

The oil tanks of S11-M and S13-M series transformers use corrugated plate radiators. When the oil temperature changes, the expansion and contraction of the corrugated plate can replace the role of the oil conservator. The corrugated plate oil tank has beautiful appearance and small floor area.
