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
S11-M S13-M series transormer tank adopts wave plate rador when the oil
temperaure change corrugated
plate heat bilges coldshrinklace storage cabinet role, corrugated
plate appearance tank, cover an area of an
area smallThe 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.
