Introduction to Products
The performances of our S9,S10,S11 series 20KV and 35KV three-phase oil-immersed  transformer conform to standards GB1094-1996 "Power Transformer" and GB/T6451-2008 "Technical Parameters and Requirements of Three-phase Oil-immersed Power Transformer". 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. It is artistic in appearance and sage in running and is widely used in transmission and distribution of industrial and agricultural networks.

Main Function and Features

High reliabity,advanced levelof performance,reasonable economical indicators
The core joints are of stepped shape with 3 steps,and the surface of the core is coated with cured paint to lower losses and noise.
The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability
The oil tank is in various types,all have good outlook.

Test / Inspection / Clients


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
- Measurement of winding resistance .
- Measurement of voltage ratio and check of phase displacement.
- Measurement of short circuit impedance and load losses.
-Measurement of no-load losses and current .
-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
- Temperature rise test
- Lightning impulse test

C - Special tests :
- Determination of noise level according to IEC 60551 .
- Oil leakage test
- 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 ) .
- Short Circuit Dynamic stability Test (test report from independent and accredited laboratory for similar transformer will be accepted).
