Inside the workshop, machines are roaring and the assembly lines are running at high speed. Workers are working at full capacity to rush out the orders. It’s a bustling production scene – this is the true picture of the production site of Nanjing High-Speed Gear Manufacturing Co., Ltd. Rows of gear products are ready to be dispatched and will be sent to all parts of the country.

Recently, news came from Nanjing High Gear Manufacturing Co., Ltd. (hereinafter referred to as “NanGao Ge”) that by the end of 2025, this global leader in wind power transmission systems headquartered in Jiangning High-tech Zone has delivered nearly one million yaw and pitch gearboxes. Among them, the domestic new delivery volume in 2025 exceeded 100,000 sets, setting a historical record. The domestic market share remains at the top of the industry and continues to lead the core components of the wind power sector.
The yaw and pitch gearbox is akin to the “intelligent joint” of a wind turbine generator. It precisely executes every “instruction” from the control system, driving the huge rotor to always face the wind direction and adjusting the angle of each blade in real time. This directly determines whether the wind turbine can maximize the “capture” of wind energy and improve the power generation efficiency of the unit; it is also the core support that ensures the safe, reliable and efficient operation of the wind turbine throughout its entire life cycle.
The achievement of breakthrough delivery results is attributed to the long-term technical accumulation and full-chain competitive advantages of NanGaoZhi. The company has mastered core technologies in the highly modularized and highly reliable design of yaw and pitch gearboxes. At the same time, it continuously optimizes the production manufacturing and supply chain management system, and builds a complete industrial ecosystem covering research and development, production, and services. With outstanding product quality and technical strength, NanGaoZhi has established long-term and stable cooperative relationships with major wind turbine manufacturers in the industry, and has become an important force in the wind power industry supply chain.

It is worth noting that the outstanding performance of the yaw and pitch gear box business has formed a strong synergy with the main gear box business of NanGaoZhi Wind Power, further consolidating its leading share in the wind power transmission system market. This also demonstrates the large-scale manufacturing capabilities and high-quality development characteristics of local enterprises in Jiangning in the field of high-end equipment manufacturing.
Looking to the future
NanGao’s wind power industry focuses on technological upgrading. It will continue to promote capacity expansion and technological innovation, drive the development of yaw and pitch gearboxes towards higher integration and extreme lightweighting, lead the Jiangning wind power equipment industrial cluster to improve quality and efficiency, enhance the development strength of Jiangning’s advanced manufacturing industry, and provide stronger impetus for Nanjing to build a nationally leading high-end equipment manufacturing cluster and contribute to the realization of the “carbon neutrality” goal.
