rated voltage class

Rated voltage level series for power systems and electrical equipment. The rated voltage is the normal voltage specified by the power system and electrical equipment, that is, the nominal voltage associated with certain operating characteristics of the power system and electrical equipment. The actual operating voltage of each point of the power system is allowed to deviate to some extent from its rated voltage. Within this allowable deviation range, various power equipment and power systems themselves can still operate normally.
