The CEI85 standard defines the insulation classes. It classifies the motors according to the heating capacities of their insulators.
The temperature reached by the insulators limits the lifetime of an electric apparatus. The insulation class is defined by the insulator with the lowest temperature.
There are three criteria:
• The maximum ambient temperature
• The maximum permissible heating
• The thermal reserve
Also, we can distinguish the classes:
The kelvin (K) is a temperature unit. It corresponds to a differential of 1°C and the zero value is -273.15°C (absolute zero).
For its actuators, Valpes uses class B (400V) and class F (other) motors.
