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.

This product is widely used for national defense, mechanical processing equipment, transportation, communications, scientific research, industry, transportation, railways, large electromechanical equipment, metal processing equipment, CNC machine tools, printing machines, laser cutting machines, production lines, construction engineering equipment, elevators, medical equipment, Embroidery textile equipment, air-conditioning, radio and television, household appliances, lighting, new energy and other power-consuming occasions that need to change the voltages.
