Product Description

Oil-Filled Transformer ZTELEC S11 0.4KV-35KV Oil Immersed Power

Transformer

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.
