JB/T 9740.1-1999 This standard is a revision of NJ 350-85 "Low-speed Wind Turbine Series". During the revision, the wording and values ​​of "speed limit mode" and "wind speed" were modified. This standard applies to multi-blade horizontal axis wind turbines with a blade tip speed ratio of less than 2. This type of wind turbine is mainly used to drive some water-lifting equipment and can also be used as a power source for other equipment. This standard was first issued on March 5, 1985.

This standard is a revision of N350—85 "Low speed wind turbine series". The main contents of the revision: "Standard high speed performance" will be changed to "tip speed ratio" and "rated wind speed 8m/g" will be changed to "design wind speed 6-9m/s". The value of "Speed ​​limit type: wind wheel deviates from wind direction" is changed to "wind turbine should have reliable tracking device" and added - other equipment matching with the wind turbine, refer to the corresponding standard". This standard replaces NJ35085 from the date of implementation. Appendix A of this standard is the appendix of the standard. Appendix B and Appendix C of this standard are both informative appendices. This standard is part of the JB 974 "Low Speed ​​Wind Turbine" series of standards, which includes the following parts: JB/F9740.1w-199y
