Product series
6kV, 6.3kV, 10kV, 11kV, 22kV, 33kV  and 35kV Distribution  transformers produced by Shenda Electric comply with standard  IEC 60076 and requirements of three phase immersed power transformer". The core is made of superior grain-oriented cold- rolled silicon steel sheets and all inclined lapped joints without drilled holes while the coils are made of copper free of Oxygen with beautiful appearance and safe running. They are widely applied to power transmission & distribution of urban & rual network. These transformers are widely applied to eletrolysis, transmission, traction, DC transmission and electrostatic precipitation fields. These transformers are certified by KEMA, CESI, V-check, CTQC, ISO9001 & 14001 and CE, our brand EACHER is the famous brand of Zhejiang province. SHENDA is a worldwide partner for all power applications and industrial companies-Accordingly, the examples of our work are Global: Whether in South America, Asia or Europe, Whether in the desert or in specially demanding Applications. Thousands of plants run efficiently and reliably with our technology.

Test lab
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).
