AC switches for the Maglev-project in China

The Astrol AC switch accelerates the 1000 km/h maglev train of the future

The ultra-fast maglev train travels in a low air pressure tube without contacting rails, thereby avoiding friction and air resistance. Several projects in different countries are currently lifting this fascinating technology to the next level. In the recently started project in China an array of Astrol AC switches distribute electric power to different line sections. Enabling contact-less acceleration of the train units to mind-blowing speeds.

About the Shanghai Maglev train

The Shanghai maglev train or Shanghai Transrapid is a magnetic levitation train line that operates in Shanghai, China. Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of electromagnets; one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction. Such trains rise approximately 10 centimetres off the track.

The Shanghai Transrapid is the world’s first commercial high-speed maglev. It is the fastest commercial electric train and also the fastest overall operational rail network in the world with a cruising speed of 431 km/h (268 mph).
