Power transformers are crucial components in electrical power systems, with oil-immersed transformers being widely used due to their excellent cooling and insulating properties. However, recent research has highlighted significant safety concerns that demand attention. A groundbreaking study published in Case Studies in Thermal Engineering (2024) by Jia et al. reveals critical insights into arc fault behavior in transformer oil.
According to Jia et al.'s research at Xi'an Jiaotong University, when an arc fault occurs in transformer oil (5kA, 30mm gap, 80ms duration), several concerning phenomena emerge:
| Time Parameter | Main Bubble Temperature | Average Temperature |
|---|---|---|
| Initial | 2200K | 2550K |
| Final | 1400K | 550K |



The study also revealed significant changes in gas composition:
We, Aputon Electrical Co., Ltd., have a better solutions addressing these critical issues:
✓ Higher thermal resistance
✓ Enhanced breakdown voltage
✓ Superior cooling properties
✓ Advanced additives for bubble suppression
If you still have some doubts about oil-immersed transformers, we have better products. For environments where oil-related risks are unacceptable, our dry-type transformers offer:
| Feature | Benefit |
|---|---|
| No oil required | Zero fire risk from oil |
| Environmentally friendly | No contamination risk |
| Lower maintenance | No oil monitoring needed |
| Indoor installation | Space-saving design |
| Aspect | Traditional Oil-immersed | Our Enhanced Oil-immersed | Our Dry-type |
|---|---|---|---|
| Safety Risk | High | Medium | Low |
| Maintenance Cost | High | Medium | Low |
| Environmental Impact | High | Medium | Minimal |
| Initial Cost | Medium | High | High |
| Cooling Efficiency | Excellent | Excellent | Good |
We provide comprehensive support:
Our transformers incorporate lessons learned from recent research, including the findings from Jia et al. (2024). By understanding the complex behavior of arc faults in transformer oil, we've developed solutions that significantly reduce associated risks.
While traditional oil-immersed transformers present certain risks, our enhanced designs and dry-type alternatives offer superior safety and reliability. By combining cutting-edge research with practical engineering solutions, we provide transformers that meet modern safety and efficiency standards.
