Main functions and features
Good economic
On the basis of 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
Transformer tank adopts fully sealed structure, which can be bolted
or welded along the tank.
Transformer oil does not contact with air and prolongs service
life.
Running high reliability
The relevant parts of tank seal are improved to increase the
reliability and improve the
technological level to ensure the reliability of seal.
Field area is small

The transformer tank of S11-M and S13-M series adopt corrugated plate radiators. When the
oil temperature changes, the thermal expansion and contraction of
corrugated plate can replace
the role of oil conservation. The corrugated plate tank has beautiful appearance and occupies
small area.
