Product Description

oil-immersed transformer S11,30-2500KVA,10KV series,3 phae/full sealed/double winding                              factory directly supplied 10kva oil transformerHigh Voltage Transformer 0

Product Description

The performances of model S9-M, S10-M, S11-M 22kv series full-sealed oil-immersed distribution transformes conform to Standards IEC. Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality oxygen-free copper.

 

Test

 

Testing are conducted for every transformer before delivery.Tests are classified to be routine tests and type test.
A - Routine tests:
According to IEC 60076 standard , the following tests must be carried out for all units of the transformers
a- Measurement of winding resistance .
b- Measurement of voltage ratio and check of phase displacement. c- Measurement of short

circuit impedance and load losses.
d-Measurement of no-load losses and current .
e-Dielectric routine tests including the separate source AC voltage withstanding test and short

duration induced over voltage withstanding test ( ACSD ) .


B - Type tests :
The following tests shall be carried out a- Temperature rise test
b- Lightning impulse test


C - Special tests :
a- Determination of noise level according to IEC 60551 . b- Oil leakage test
c- Overload test at 150 % rated current for one hour after temperature rise test ( top oil

temperature rise and winding temperature rise must be measured and recorded in the report test

also hot spot temperature rise must be calculated and recorded on the report test ) .
d- Short Circuit Dynamic stability Test (test report from independent and accredited

laboratory for similar transformer will be accepted).

 

Application
This product is widely used in urban and rural power grid construction and renovation projects. This product is especially suitable for areas where there is insufficient power and load fluctuations and where daily maintenance is difficult. Because the transformer adopts a fully sealed structure to prevent the transformer oil from coming into contact with the air, it can operate in a humid environment and is an ideal power distribution equipment in urban and rural distribution networks
