The China XD Group (Chinese: 中国西电集团) is a Chinese state-owned power engineering company and manufacturer of electrical equipment. Established in July 1959, China XD Group was formerly known as Xi'an Electric Machinery Manufacturing Company (Chinese: 西安电力机械制造公司), Xi'an XD, Xi'an Xidian, and Xi'an Electric (Chinese: 西电 for short).
Business overview
XD Group specializes in the research, development, design, production, sales, testing, and engineering of power transmission, distribution, and control equipment. Its core business focuses on the production, research, and testing of high voltage, extra-high voltage, and ultra-high voltage AC/DC power transmission and distribution systems. The company's leading products comprise high voltage switches (GIS, GCB, isolating switches, ground switches) at 110kV and above, transformers (power transformers, converter 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, and direct current transportation valves.
XD Group's subordinate research institutions constitute China's experimental research establishment of agencies involved with high voltage, high current and large capacity AC/DC. They have become members of the International Electrotechnical Commission (IEC), the International Conference on Large High Voltage Electric Systems (CIGRE), and the specified administrative department of the IEC in China along with the relevant international Secretariat. In recent years, according to the needs of key national projects and the Economy of China, XD Group has been increasing its research efforts and implementing technical reforms, resulting in over 1300 new products, of which 281 reached the international most advanced level, 230 items reached the national most advanced level, 11 items won national scientific and technical awards, and 136 items won provincial or ministerial scientific and technical awards. Furthermore, 260 patents were authorized, and two items fall under computer software copyright.
XD Group promotes the technology of power transmission and distribution equipment in China and provides key equipment for national key engineering projects. The company provides power transmission and distribution equipment and related services for national engineering projects including 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 of China back-to-back DC transmission engineering, Three Gorges Project, and a west-east electricity transmission project. Among them, products like transformers of 750kV, reactors, lightning arresters, capacitor voltage transformers and isolating switches of 800 kV have been operated successfully in 750kV model projects in the northwest of China. China's first 800kV double cut-off pot-style breakers have been put into operation at Yinchuan East Transformer Substation.
XD Group was the first to develop technology for AC 1100kV and DC ±800kV (extremely high voltage) products in China, providing such products as 1000kV GIS, reactors, capacitor voltage transformers, lightning arresters, ground switches, insulators, etc., for the megavolt model line “Southeast Shanxi—Nanyang—Jingmen Model Project” and such products as transformers, valves, capacitors, 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, such as Germany, United States of America, Singapore, and Hong Kong.
Business areas
Currently, China XD Group owns around 40 subsidiaries, including 10 major or medium-sized production enterprises and three research institutions (which include three national testing centers). The company employs more than 18,000 people, with over 3,000 of them working as engineers and technicians.
China XD Group's main business includes the research and development, design, production, sales and testing 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, research, development and testing of high voltage, extra high voltage and extreme high voltage AC/DC power transmission and distribution equipment. Its leading products include 110 kV and above voltage level of high voltage switches (GIS, GCB, isolating switches, ground switches), transformers (power transformers, converter 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. China XD Group is the production base of high voltage, extra high voltage and extreme high voltage AC/DC power transmission and distribution equipment and other electrical products.
China XD Group's participation in the Belt and Road Initiative
Since the Belt and Road Initiative was proposed in 2013, China XD Group has actively participated in overseas projects. As of 2023, the company's products and technologies have been exported to over 100 countries and regions. Major projects include:
Southeast Asia:
Indonesia: Established a joint venture to produce 500kV power transformers
Philippines: Constructed the MVIP HVDC transmission project
Laos: Completed the Hongsa power transmission and transformation turn-key project
Malaysia: Undertook transmission line projects
South Asia and Middle East:
Pakistan: Built the first ±660kV HVDC transmission line
Saudi Arabia: Supplied equipment for the NEOM water electrolysis hydrogen production project
Uzbekistan: Signed a 500kV ring transmission line EPC project
Africa:
Egypt: Won bids for two substation projects, with a total value of about 257 million yuan
Wind farm
In 2013, XD planned to assist Uzbekistan in constructing wind farms as its first major wind power project. A Memorandum of Understanding (MoU) was signed with Uzbekenergo, the country's governing body for energy, to conduct a feasibility study on the establishment of wind farms.
