Dry Type Step-up& Step-down isolation Transformer consists of cylindrical winding and laminated core.The iron core is made of Taiwan high-quality silicon steel silicon steel plate stacking, full-oblique seams. Winding using the whole row delamination winding method. After twice vacuum pressure dipping, and 110 ℃ high temperature baking for 4 hours, the insulation of the transformer can achieve grade F or H-class. Full load temperature would not exceed 65 ℃. Finally, three is almost no noise and vibration phenomenon.

·Energy-saving and low-noise: high-quality cold-rolled silicon steel sheets are used for stacking; the vacuum dipping process effectively reduces the vibration and noise during operation; through the introduction of new processes and new technology manufacturing, the energy-saving effect of the transformer is effectively improved.

 

·High reliability: The products are manufactured in full accordance with the latest national dry-type power transformer standards, with reasonable structure, high efficiency, undistorted waveforms, long-term safe operation and stable performance.

 

·Environmental protection features: The products fully comply with the national low-carbon standards, with heat resistance, moisture resistance, stability, chemical compatibility, low temperature resistance, radiation resistance and non-toxicity.

 

·Voltage conversion functions(eg:△/Yo or Yo/ △connection)

 

·Filter anti-interference function(eg:Can remove three times harmonics)

 

·With the function of heat resistance, moisture resistance,stability, chemical compatibility, low temperature resistance, radio resistance and non-toxic environmental protection, etc.
