GB 30254-2013 English PDF (GB30254-2013)

This Standard specifies the energy efficiency grade, minimum allowable values of energy efficiency, energy saving evaluation value and test method of large and mediumsized cage three-phase high voltage induction motors. This Standard is applicable to continuous duty (S1) vertical and horizontal motors and flameproof motors with 50 Hz three-phase AC power supply, of which, it is 6kV voltage level (cooling method IC01, IC11, IC21, IC31, IC81W) when rated power is 220kW ~ 25000kW; 10kV voltage level (cooling method IC01, IC11, IC21, IC31, IC81W) when rated power is 220kW ~ 22400kW; 6kV voltage level (cooling method IC611, IC616, IC511, IC516) when rated power is 185kW~2500kW; 6kV voltage level (cooling method IC411) when rated power is 160kW~1600kW; the number of poles is 2~12 poles.
