Bipolar fork connector (GSR2.5)
Application: connection between busbar and laminated busbar in IGBT
China is home to the largest and most extensively used network of high-speed trains in the world. Based in Beijing, the Chinese Academy of Railway Sciences (CARS) is the leading research and development institute, supporting this important industry with its specialized subsidiary, the Beijing Zongheng Electro-Mechanical Technology Development Co. Electrical Connectors helped to develop a traction converter for the latest generation of Chinese high-speed trains, while building up a partnership.
China’s network of high-speed railways covers a total of over 22,000 km of tracks. Just imagine: if you could put these rails in a straight line, they would take you halfway around the globe – and even a little further. Every day, thousands of Chinese are using high-speed trains, running at 250 to 350 km/h. The possibility of fast travel and commuting has profoundly transformed the country’s economy and society.
CARS: A key player in China’s railway industry
When China launched its first high-speed trains, they were imported or built under technology transfer agreements with foreign train-makers. After this initial technological support, Chinese engineers have re-designed train components and started building indigenous trains. Thanks to generous funding from the government, a dynamic local industry has developed over the past 15 years.
An important player in this market is the China Academy of Railway Sciences (CARS). Based in Beijing, CARS offers scientific and technological education as well as strategic consultation and certification services for the Chinese railway industry. A focal theme is research and the testing of new materials, products and technology.
A traction converter for the new generation
In 2010, CARS updated an existing traction converter for use in the latest generation of Chinese high-speed trains. The connector fixed on the water-cooled board contains two poles and connects the IGBT module (insulated gate bipolar tra
