Table 1 temperature limit
| Title | B-class insulation | F class B insulation |
| Top layer oil (k) | 80 | 100 |
| Winding (averagely) (k) | 85 | 100 |
| Winding (focus) (k) | 95 | 110 |
The A class B insulation (65 k) of common oil-filled transformer can not meet temperature increase requirement as can be seen here, and when transformator temperature rise reaches 100 k, its A class B insulation (transformator) life-span significantly declines, the potential safety hazard caused.
