Nanjing Turbine & Electric Machinery (Group) Co., Ltd. is located in the northeast of the lofty purple mountain, beautiful southern Yangtze river, formerly known as Nanjing Turbine & Electrical Machinery Works, established in January 1956, in November 1995 to change a wholly state-owned limited liability company, in October 2004 for Nanjing and Hong Kong joint venture enterprise restructuring.
The company covers an area of 425,000 square meters. There are about 2000 employees in the company, in which 25% are technicians and engineers. There are more than 1700 sets of various main manufacturing equipment including 213 sets of large and precision machining tools, such as HBM, NC lathe, ND planer, NC rotor slot miller as well as large test equipment such as gas turbine test stand, generator and large motor test stand, turbine governing system test stand, 100t and 50t high speed dynamic balancing machines and three coordinates measurement instrument which owns very strong large and precision machining and inspection and test capability. The main products are heavy duty gas turbine generating units and gas-steam combined cycle power equipment, co-gen steam turbine generating units, wind generators, large and medium sized motors, which forms annual production turnout integration of 10GW.
The company is the national point of heavy duty gas turbine manufacturing base, the respective gas turbine research institute for the Ministry of Machine Building gas turbine industry professional, not only engaging in gas turbine product related technical work for this enterprise, but also bearing the national machinery industry gas turbine industry technical management functions. It is the national gas turbine standardization technical committee secretary unit. The company has nearly 50 years history for manufacturing gas turbines. In the mid of 1980s the company set up the manufacturing association with GE Co. (USA) to produce Frame 6B gas turbines (40MW Class), in 2004 imported GE technology to produce Frame 9E gas turbines (125MW Class), in 2012 signed technology transfer agreement on Frame 6FA gas turbine (75MW Class). Till now, the company has manufactured and sold nearly 100 sets of Frame 6B and 9E gas turbines and most of them are high efficiency energy saving gas-steam combined cycle power plants. The products in addition to meet the domestic demand and also export to Southeast Asia, South Asia, Africa, the Middle East and other countries.
The steam turbine products use current world leading full dimension stream technology to design and manufacture. The output of steam turbine is ranging from 6 to 330MW. The steam turbines cover more than 160 types such as straight condensing, extraction, back pressure, extraction back pressure, from MP, HP parameter simple cycle to super high pressure, sub-critical parameter reheating cycle, mainly using for co-gen and combined cycle power station, and involved in industrial driving, power generation by wastes, biomass power generation as well as waste heat waste energy recycling in industries such as iron and steel, metallurgy, chemical, cement and glass.
The generators are matched with gas turbines and steam turbines ranging from 6MW to 350MW. In 1980s the company imported air-cooled brushless excitation technology from BURSH (UK). In the digestion and absorption of the imported technology and absorbing the advantages of others, the company has independently researched and developed QF, QFW, QFR series products and TRT blast pressure recovery turbine units, fully used stator bars VPI dry resin insulation structure and whole stator VPI process, which showed reliable quality and remarkable performance. There is various of large and medium sized AC motors ranging from 130KW to 5000KW with different voltages 380V, 6000V and 10000V. These motors could be matched with compressor, pump, blower and cement machinery for widely use in mines, iron and steel mills, petroleum and chemical plants, cement plants and water conservancy projects.
In 2007, the company involved in wind power field, produced wind generator stator for main wind turbine factories, later imported the mature technology from VEM (Germany) to produce 1.5MW - 2MW double-fed asynchronous wind generator. In 2010 wind power manufacturing base located in Jiangning Science Garden was built up and put into operation. The current wind generator annual output is more than 1000 sets. The wind generator has occupied the market with advanced technology, compact structure, safe and reliable. Now the company has become the wind generator qualified suppliers of GE Co.
The company has got the authentications of ISO9001-2000 standard quality system, ISO14001 environmental management system, GB/T28001 occupational health and safety management system and national level of safety quality standardization machinery manufacturing enterprise the authentication, won the national, provincial observing contract and valuing credit advanced enterprise of Jiangsu province, Jiangsu province, quality management award. Gas turbine generating set is brand-name products in Jiangsu province and co-gen steam turbine won the Chinese famous brand product.
The company has always been adhering to the "customer first, service permanent, green energy, harmonious development" concept, advocating "Honesty, Creativity, Harmony and Win-win" the spirit of willing to wholeheartedly for the domestic and foreign customers to provide quality products and satisfactory service. Welcome the domestic and foreign new and old friends come to us for future cooperation.
