Company Profile: Nanjing Steam Turbine & Electric Machinery (Group) Co., Ltd. is located at the northern foot of the majestic Zijin Mountain and on the beautiful southern bank of the Yangtze River. It was originally named Nanjing Steam Turbine & Electric Machinery Works, established in January 1956. In November 1995, it was restructured into a wholly state-owned limited liability company, and in October 2004, it became a Ning-Hong Kong joint venture.

The company covers an area of 425,000 square meters, with over 2,000 employees, 25% of whom are professional technical personnel. It has over 1,700 main production equipment, including 213 large, precision, and rare equipment such as large CNC floor boring and milling machines, CNC horizontal lathes, CNC vertical lathes, and CNC rotor slot milling machines. It also has large testing facilities such as gas turbine complete unit test benches, generator and large motor complete unit test benches, turbine regulating part test stations, 100-ton and 50-ton high-speed dynamic balancing machines, and CMMs, demonstrating strong capabilities in large-scale precision machining and testing. Its main products include heavy-duty gas turbine generator sets and gas/steam combined cycle power generation equipment, combined heat and power steam turbine generator sets, wind turbine generators, and large and medium-sized AC motors, with an annual comprehensive production capacity of power station equipment exceeding 10 million kilowatts.

The company is a designated national heavy-duty gas turbine manufacturing base. Its Gas Turbine Research Institute was the designated research institute for the gas turbine industry under the former Ministry of Machine Building Industry. It not only engages in technical work related to the company's gas turbine products but also undertakes the technical management functions for the national machinery industry's gas turbine sector, and serves as the secretariat unit for the National Gas Turbine Standardization Technical Committee. The company has nearly fifty years of gas turbine production history. In the mid-1980s, it established a partnership with GE Company of the United States. 6B series gas turbines ( 40MW class) cooperative production relationship, 2004 year introduced GE company's technology began production of 9E gas turbines ( 125MW class), 2012 year also with GE company signed a 6FA gas turbines ( 70MW class) technology import agreement. To date, accumulated production and sales of 6B、 nearly one hundred 9E gas turbine sets, most of which form highly efficient and energy-saving gas-steam combined cycle power plants. In addition to meeting domestic demand, products are also exported to Southeast Asia, South Asia, Africa, the Middle East, and other countries.

The company's steam turbine products are designed and manufactured using today's world-leading full four-dimensional flow technology, with single unit power ranging from 6-330MW, covering over 160 varieties including condensing, extraction, back-pressure, and extraction back-pressure types. They have evolved from simple cycle with medium and high pressure parameters to supercritical and subcritical reheat cycles, and are mainly used in combined heat and power (CHP) and combined cycle power plants, also involving industrial drives, waste-to-energy, biomass power generation, and waste heat/energy recovery and utilization in industries such as steel, metallurgy, chemical, cement, and glass.

The company's generator products are matched with gas turbines and steam turbines, with single unit power ranging from 6-350MW. In the 1980s, the company introduced technology from the UK's BRUSH company's air-cooled brushless excitation technology. After digesting and absorbing the introduced technology and drawing on the strengths of various manufacturers, it independently developed QF 、 QFW 、 QFR and other series products, as well as TRT blast furnace top gas recovery turbine units. It also fully adopts stator coil bars VPI resin-poor insulation structure and whole machine VPI impregnation process, ensuring reliable quality and excellent performance. The company offers a complete range of large and medium-sized AC motors, with single unit power 130 — 5000KW , voltage level 380、6000 , 10000V, matched with compressors, water pumps, fans, and cement machinery, etc. They are widely used in mining, steel, petrochemical, cement, and water conservancy industries.

In 2007, the company entered the wind power sector, producing wind turbine generator stators for main engine manufacturers. Later, it introduced mature technology from Germany's VEM company to produce 1.5MW-2MW doubly-fed asynchronous wind turbine generators. In 2010, its wind power manufacturing base in Jiangning Science Park was completed and put into operation. Currently, the annual output of wind turbine generators exceeds 1,000 units, establishing its reputation in the market for advanced technology, compact structure, and reliable safety, and has now become a qualified supplier for GE Wind Energy in the United States.

The company has passed ISO9001-2000 quality management system, ISO14001 environmental management system, GB/T28001 occupational health and safety management system certifications, and the national first-class safety quality standardization certification for machinery manufacturing enterprises. It has been honored as a national and provincial advanced enterprise for honoring contracts and maintaining credit, and received the Jiangsu Provincial Quality Management Award. Gas turbine generator sets are a famous brand product in Jiangsu Province, and combined heat and power steam turbines have won the China Famous Brand Product award.

The company always adheres to the philosophy of 'Customer First, Service Forever, Green Energy, Harmonious Development' and advocates the spirit of 'Integrity, Innovation, Harmony, and Win-Win'. It is committed to providing high-quality products and satisfactory services to domestic and international customers, and welcomes new and old friends from home and abroad to cooperate and create a better future!
