Scope

This standard specifies the test samples, technical requirements, test methods, and
inspection rules for stator coils (frame coils) of high-voltage AC motors, which have a
heat resistance grade 155 (F) and rated voltage UN of 3 kV, 6 kV, 10 kV, including stator
coils manufactured by molding and VPI (Vacuum Pressure Impregnating) processes.
This standard applies to the quality appraisal of the insulation structure of finished coils
of high-voltage AC motors, which have a rated voltage of 3 kV, 6 kV, 10 kV.
