Insulation class classification
As per NEMA class of insulation for transformer is based on the max. An R-Class insulation transformer uses very high-temperature resistant materials, allowing its windings to reach a maximum hot-spot temperature of 220°C.
| Insulation Class | Maximum allowable temperature rise (°C) |
environmental temperature (°C) |
Maximum Temperature (°C) |
Common Insulation Materials |
| Class A | 50 | 40 | 105 | Cotton, Paper, Silk, Wood |
| Class B | 80 | 40 | 130 | Mica, Fiberglass, Asbestos, etc., with suitable bonding substances |
| Class F | 105 | 40 | 155 | plus materials like synthetic enamelsB |
| Class H | 125 | 40 | 180 | Silicone elastomers, Mica, Fiberglass with high-temperature bonding substances |
| Class R | 150 | 40 | 220 | Very high-temperature resistant materials, often proprietary |
