一、 Power Transmission Industry            Bearing the value of “Serving the Country With Industry, Casting Into World-Famous Brand”, after continuous innovation and development in the past decades, Tianwei Group has been in the leading position in research and development of UHV AC/DC large transmission key equipments, and has become an important Enterprise in China for manufacturing momentous equipments. Possessing the three modern transformer manufacture bases separately in Baoding, Hefei and Qinhuangdao, and with the support of the National Level Technology Center located in Baoding, Tianwei Group has become a large group who has gained complete core technology of transformers, most varies of products and most advanced production equipments. It has mastered the most advanced transformer manufacture technology in the world and has a production capability of 1000kV and below core type and shell type power transformers, 800kV and below core type and shell type reactors, ±800kV and below converter transformers, 500kV and below instrument transformers and 220kV and below special type transformers of all kinds. Tianwei Group always persists in scientific development and upholds independent innovation. With this development strategy, Tianwei Group has manufactured units of internationally advanced products and makes them milestones in the transformer development history in China: the fist unit of 500MVA/750kV transformer, the first unit of 300MVA/230kV PST, the first unit of 720MVA/500kV three-phase bank transformer, the first 500MVA/500kV transformer for nuclear power station and the first 370MVA/500kV single phase transformer equipped for the 1000MW generator bank, the first single 18-phase rectifier transformer, AC-AC frequency conversion transmission commuting transformer, AC_DC_AC frequency conversion transmission commuting transformer and so on. Up to now, Baoding Tianwei 500kV transformers still boast the glory of zero accident rates in the past 20 operation years.          Tianwei Group has founded professional manufacturing base for transformer copper conductors, cooling equipments, rubber sealing products so it can provide for 100kV-1000kV transformers first-class CTCs, compound conductors, paper wrapped conductors and varnished conductors, for 1000kV and below transformers first-class low-sound level and low energy –cost coolers, and first-class rubber sealing products with Anti-aging, Anti-corruption and excellent sealing efficiencies for transformer, machinery, car and architecture. Tianwei Group and Mitsubishi Motor together established a joint venture named Baoding Mitsubishi Motor Tianwei Transmission Equipment Co., Ltd which can provide internationally advanced GIS HV switches for power systems. And Tianwei Group has the research and development and manufacturing capability of electric automation equipment such as relaying protection and electric control.

二、Green Energy Industry          Tianwei Group has been paying closely attention to the world development trend of energy and has been following the energy development policy of the state. With acute market foresight and advanced strategic insight, Tianwei first chooses photovoltaic products as the representative products to enter green energy industry and subsequently matches into wind power field. The combination of solar energy and wind power formed the green energy industry which is one of the “Two Main Industries” of the Group. In green energy field, Tianwei Group has established 3 subsidiaries:  Tianwei New Energy Holdings Co., Ltd , Tibet Huaguan Photovoltaic Science and Technology Co., Ltd and Tianwei Yingli Green Energy Co., Ltd .  Tianwei Group has already obtained a series of international certifications including: UL, CE, IEC, TUV and ISO9001. Tianwei Group has the complete industry chain and the solid technology research and development strength and rich experience on photovoltaic application system and power station construction. Tianwei Group is also the second large shareholder of Sichuan Xinguan Sillicon Co., Ltd. The successful trial operation of the only 1260 tons silicon production line in China remarks that Tianwei Group has occupied the High Ground of the upper bank in photovoltaic industry. Tianwei Wind Power Science and Technology Co.,Ltd is a company involved in wind power. The strategy for the company has been confirmed and the new factory is under construction. The products will be in compliance with the development trend of wind power technology in the world. The capacity of the products covers 1.2MW, 1.5MW, 2.5MW. Wind power generating has become an important project of Hebei Province.

三、Other Industries of the Tianwei Group        Besides above-mentioned two main industries, the Tianwei Group is also specializing in developing and selling of electric mechanical device, optical-mechanical-electrical integration of complete sets of equipment and transformers, accessories; researching and developing intelligent online monitoring equipment for large power transformers, and various detection equipment and sales them; manufacturing and selling multicrystalline polysilicon ingots and wafers, photovoltaic(PV) cells, PV modules and PV systems, and fibre textile slings, and other products.
