Product feature
3 phase oil transformer with high voltage for distribution power,also can called S11-M(R)
transformer,it's compact and with strong over-load ability,low temperature rise and noise.
It can save about 30% no-load loss than S9 series oil immersed sealed current
transformer,and save about 40%-80% no load current.
Standard:
GB 1094.1,.2-2013
GB/T6451-2008
GB1094.3-2003
GB1094.5-2008
Benefits:
1. It's an environment-friendly transformer with low no-load loss,no-load current and noise;
2. No oil storage box to save space(but we can offer transformers with oil storage box);
3. Whole sealed with vacuum oil filling,high stability of insulation;
4. Adopts the corrugations on the oil tank as its heat-radiation parts,corrugations can
expand or contract accord to the change of oil volume;
5. Fully sealed structure,maintenance free;
6. with oil level gauge to ensure the satety running.

SCOPE of application
Because of the need of fire prevention, oil-immersed transformer is usually installed in a single
transformer room or outside, which has the characteristics of large volume, low cost, simple
maintenance, good heat dissipation, strong overload capacity and wide adaptability to the
environment.
In operation of oil-immersed transformer, the heat of winding and iron core is first transmitted
to oil, and then to cooling medium through oil. oil-immersed transformer equipment uses oil as
the main insulationmeans of transformer, oil-immersed transformers are widely used in power
plants, steel plants, railwaysand other large-scale mechanical manufacturing industries.
oil-immersed transformers rely on oil as cooling medium. It is suitable for power system of
petrochemical, electric power, light textile, metallurgy,machinery, building materials, coal, mine,
city construction, civil aviation, port and other industries and enterprises, as rated frequency 50HZ,
rated capacity 30 ~ 1600KVA, rated voltage 10KV on high voltageside, low voltage side rated voltage
0.4 kv power distribution.
