1. Stable electrical performance:


The product combined with load characteristics and grid voltage fluctuation, atmospheric overvoltage situation, according to the rectifier transformer load conditions determine reasonable and reliable insulation level and insulation model, confiscated products to ensure reliable and stable electrical performance. Product environmental safety factor ≥1.67.


2. high degree of dynamic stability:


The product winding has high mechanical strength, has a strong anti-burst capability to meet the harsh load environment. In the design, manufacturing process to better eliminate the transformer magnetic flux leakage caused by the abnormal transport or instability may be the source of instability. With high dynamic stability, high resistance, it has the capacity of the power transformer impedance of 30% higher, effective protection of rectifier components.


3. good thermal stability:


Advanced product design, strict control of the product hot spots and the hottest temperature rise, and leave sufficient temperature margin, if necessary, can be added in the coil axial oil path, according to the coil Load loss value of the cooling method and reasonable distribution of oil flow to achieve cooling effect, the main temperature indicators are at least 5 ºC lower than the national standard. Coil, copper wire used lead, current density selection is lower.


4. strong overload capacity:


the product has strong overload capacity and over-voltage capability, rated load conditions in the long-term safe operation, over-voltage conditions in 110% of the long-term safe operation under full load (ambient temperature 40 ºC); Transformer and motor connected terminals can withstand 1.5 times the rated current, duration 5S. Product design, manufacturing fully consider the load characteristics, from the temperature rise, insulation properties and accessories to meet all aspects of the choice of overload requirements.


5. superior performance indicators:


No-load current design, manufacturing value is lower than the same capacity transformers based on the provisions of the full user economy and reliability.


6. energy-saving effect is obvious, low noise (<65dB).

Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.
