1 Class A insulation: For electrical equipment with a maximum working temperature of 60°C or less.
2, Class B insulation: applicable to electrical equipment with a maximum working temperature of 75°C or less.
3, Class E insulation: applicable to the maximum operating temperature of 120 ° C below the electrical equipment.
4, F-class insulation: for the maximum operating temperature of 155 ° C below the electrical equipment.
It should be noted that the same level of rubber insulation, there are differences in its performance. Because of the different formulas and processes of rubber materials, the performance of the same insulation grade products of the same grade of insulation will be different.
