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.
