(August 5, 2009)

  China XD Group (the former Xi’an Electrical Machinery Manufacturing Company;hereinafter called XD Company for short) was established in July, 1959. On the basis of 5 projects of the 156 key construction projects in the first five-year plan, it has developed to be a large-size enterprise group taking research institutions and backbone enterprises as its core as well as merging research, development, production, trade and finance as an organic whole. In 2001, being approved by the State Administration for Industry and Commerce of the People's Republic of China, China XD Group was established formally with XD Company as its parent company. In 2003, XD Company became the only central enterprise of the power transmission and distribution industry under the supervision of the State Property Management Commission of the State Council. On May 6, 2009, being approved by the State Administration for Industry and Commerce of the People's Republic of China, China XD Company formally changed its name to be China XD Group and decided to name it XD Group for short.
  XD Group’s main business includes the research and development, design, production, sales and examinations of power transmission and distribution and control equipment, relevant equipment technology and service in a complete set, engineering contracting, etc. Its core business is the production, the research and development and the examinations of high voltage, extra high voltage and extreme high voltage AC-DC power transmission and distribution equipment. Its leading products include 110KV and above voltage level of high voltage switches (GIS, GCB, isolating switches, ground switches), transformers (power transformers, convertor transformers), reactors (smoothing reactors,shunt reactors),power condensers,instrument transformers(CVT、CT、PT),insulators (power substation electric porcelain products,composite insulator products),cannula, zinc oxide arresters, direct current transportation valves, etc. After a half century’s struggle and development, XD Group has become the production base of high voltage, extra high voltage and extreme high voltage AC-DC power transmission and distribution equipment and other electrical products, which has the largest scale and strongest capacity of complete set in China.
  At present, XD Group owns over 40 wholly-owned enterprises or holding enterprises, during which there’re 10 large or medium key production enterprises and 3 research institutions (including 3 national testing centers). It has more than 18000 employees, and over 3000 of them are engineers and technicians, including 529 persons with intermediate and senior professional titles, 35 experts enjoying the government special subsidy that the State Council distributes, and 49 young experts with outstanding contributions at the provincial and municipal level. During the years, XD Group has made a great breakthrough in the key technical field of extreme high voltage universal power transmission and distribution equipment, led the way in China in researching and developing line products for 750KV power network, and succeeded in developing 800kV GIS,couple cut-off pot-type breakers, isolating switches and transformers of 750kV, reactors, lightning arresters, etc. As China’s experimental research establishment of high voltage, intense current and large capacity AC-DC, XD Group’s subordinate research institutions have become not only the member of the International Electrotechnical Commission (IEC) and International Conference on Large High Voltage Electric Systems (CIGRE), but also the specified administrative department of IEC in China and the relevant international Secretariat. In recent years, according to the needs of the national key projects and market, XD Group has been continuously intensifying research and technical reforms, therefore it has accomplished more than 1300 items of new key products developed by itself, among which 281 items reached international most advanced level, 230 items reached national most advanced level, 11 items won national scientific and technical awards, 136 items won provincial or ministerial scientific and technical awards, as well as 260 patents were authorized and 2 items got the copyright of computer software. Now XD Group has 5 leading products which won the title China Famous Brand Products; also it has gained 16 Famous Brand Products of Shaanxi Province, 19 Famous Brand Products of Xi’an City. Its research development of every relevant technique keeps ahead both inside and outside China and has formed proprietary intellectual property rights. It won the titles of the Top 500 Chinese Enterprises, the Head of Top 500 Chinese Electricity Enterprises, the Head of Top 10 Chinese Electricity Industry with Great Competitiveness and Innovativeness. In November, 2004, it was confirmed by the State Property Management Commission of the State Council as one of the first group central large enterprises with distinctive main lines of business. In April, 2008, it won National May 1 Labor Prize.
  Acting as the head of power transmission and distribution equipment production industry in China, XD Group shoulders the duty of promoting the technology of power transmission and distribution equipment in China and providing key equipment for national key engineering projects. It once provided complete sets of power transmission and distribution equipment and services for our national key engineering projects one after another, such as China’s first 330kV and 550kV High Voltage DC Transmission Engineering, the first 750kV Extra High Voltage AC Transmission Engineering, the first ±100kV High Voltage DC Transmission Engineering, the first ±500kV Extra High Voltage DC Transmission Engineering, the first ±800kV Extreme High Voltage DC Transmission Engineering, the first power supply network from the northwest to the North China back-to-back DC Transmission Engineering, Three Gorges Project, and West-East electricity transmission project. Among them, the products, like transformers of 750kV, reactors, lightning arresters, capacitor voltage transformers and isolating switches of 800kV, have been operated successfully in 750kV model projects in the northwest; China’s first 800kV double cut-off pot-style breakers has been put into operation at Yinchuan East Transformer Substation. Besides, XD Group first developed and stored relevant technologies of AC 1100kV and DC ±800kV Extreme High Voltage products in China, provided such products as 1000kVGIS, reactors, capacitor voltage transformers, lightning arresters, ground switches, insulator, etc, for the megavolt model line “southeast Shanxi—Nanyang—Jingmen Model Project” and such products as transformers, valves, capacitor, lightning arresters, etc, for the megavolt model line “Yunnan—Guangzhou” ±800kV Extreme High Voltage DC Transmission Project. On the international markets, XD Group’s products and technology have been exported to more than 40 countries and regions and succeeded in entering the markets of some developed countries and regions, such as Germany, America, Singapore, Hong Kong, etc.
    Facing to the future, XD Group will continue to work toward its purpose that the society, the nature and resources develop in a harmonious way. It will carry forward its value pursuit of “China XD, equip electricity”, seek the joint development of the enterprise and the society, and carefully build itself to be “an international power transmission and distribution equipment supplier with proprietary intellectual property rights and famous brands”.
