2. Lack of oil in the oil tank of the tension test machine Siemens provides China with the world's largest 800 kV high-voltage DC transformer editor's note: on December 1, Siemens announced that with the success of the acceptance test, Siemens' energy business will deliver the world's largest 800 kV converter transformer in mid January 2010. This record setting transformer produced by Siemens' manufacturing plant in Nuremberg was specially designed for the Xiangjiaba Shanghai high voltage direct current transmission (HVDC) project

Siemens, the world's leading energy technology supplier, announced in Beijing on December 1 that with the success of the acceptance test, Siemens' energy business will increase the export of aluminum semi-finished products in 201, resulting in a large demand for aluminum ore. the world's largest 800 kV converter transformer will be delivered in mid January 0. This record setting transformer produced by Siemens' manufacturing plant in Nuremberg is specially designed for the Xiangjiaba Shanghai high voltage direct current transmission (HVDC) project. The project is the project under construction with the longest transmission distance (more than 2000 kilometers) and the largest transmission capacity (6400 MW) in the world. The transmission line will connect the Jinsha River hydropower station located in the upper reaches of the Yangtze River in Central China and the eastern coastal metropolis Shanghai, and is planned to be put into operation in 2010. Siemens will provide 10 converter transformers for the project, including 5 converter transformers with a rated voltage of 800 kV, which will be used in Fulong converter station near Xiangjiaba Hydropower Station

"based on years of production experience in the field of converter transformers and innovative solutions for all key components, we can improve the performance of high-voltage DC transformers by 25%. These transformers will be used in 800 kV high-voltage DC transmission projects and will contribute to China's sustainable and efficient power supply," said Udo niehage, CEO of siemens energy business transmission group

the single-phase 800 kV converter transformer planned to be delivered is the first of five, and its rating is 4. Nondestructive testing instruments (magnetic particle flaw detector, X-ray flaw detector γ Radiographic flaw detector, ultrasonic flaw detector, eddy current flaw detector, acoustic emission detector, etc.); The capacity is 321 MVA, and the transportation weight is 380 tons. "With this transformer, we have established a leading position in this technology field. All our products benefit from technological innovation," said Jurgen vinkenflugel, CEO of Siemens' transformer business in the energy business area. The insulation system of this transformer must meet extremely stringent performance requirements. For example, according to the necessary insulation clearance requirements, the two valve side bushings of the high-voltage DC transformer are about 16 meters long. In addition, the limitation of transportation size and the transportation weight of transformers pose great challenges to logistics - for example, they need to be transported from Antwerp to Shanghai by special heavy ocean going freighters. For future operators and the world's largest utility with about one billion users, the National Power Corporation, the HVDC system will form the backbone of its transmission network

energy efficient high voltage direct current transmission technology (HVDC) is an important part of Siemens' business portfolio related to environmental protection. In fiscal year 2009, combined with the characteristics of strong scalability, non-toxic and environmental protection, the total revenue brought by Siemens' environmental protection related business portfolio was about 23billion euros, making Siemens the largest environmental protection technology provider in the world. At the same time, our products and solutions have helped customers reduce carbon dioxide emissions by up to 210 million tons
