The silicon sheets we use to realize the core, are enter to our warehouse in cutted and stacked form according to our design. After many routine tests and visual inspection they moves through our manufacturing line to become a part of active part. Sometimes we purchase CRGOs in sheet form instead of stacked core. In this case, our qualified workers make the core in core assemblying line.

Silicon Steels We Use in Our Transformers:

Code :

  • M3,
  • M4,
  • M5,
  • M0H

Thickness of the CRGOs in mm:

  • 0.18,
  • 0.23,
  • 0.27,
  • 0.30

Design Models and Type : Core type (standard) / Shell Type (Optional)

In Datsan Transformer, we apply routine tests to each transformer according to IEC60076. We apply type tests and many other special test additionally in case of customer request. In case of type and/or special test request, the expenses born by the customers unless its not specified in the contract. The test results are automaticaly saved into our database. This database can be monitored by our engineers anytime. Our customers can view test results of their products anytime via our website (in case of autorization request to online monitoring, please contact to our technical dept.)

Routine Tests:

  • Measuring of winding resistances,
  • Measuring of insulation resistances,
  • Measuring of transformer turn ratios,
  • Measuring of short circuit impedance,
  • Measuring of no load losses (NLL),
  • Measuring of load losses (LL),
  • Inducted voltage test,
  • Applied voltage test.

Type Tests:

  • Temperature rise test,
  • Impulse voltage test,
  • Short circuit witstand test;

Special Tests:

  • Measuring of sound level,
  • Measurement of zero sequence impedance,

In Datsan Transformer we apply mechanical surface threatment process on each cover and tank of transformer. The next step is applying chemical cleaning and oil removing process. After these cleaning operations, the surfaces are ready for painting. We apply three coat of painting for our transformers, if there is no special customer request. Please see the operation video.

  • Paint Thickness : > 120 micron
  • Color: RAL 7033
  • Painting Standard : SS-EN ISO 12944
