The cooling of generators and inverters of electrically driven high-speed trains and railcars is a HAUGG speciality based on our many years of experience.
Our cooling concept of the asynchronous motors of the TGV POS (Alstom) enables the IGBT power packs to generate 75% of their maximum power below 15 kV in the German and Swiss power grids. This allows French TGV POS trains to operate in Germany at the same speed as Intercity Express trains.
On 3 April 2007, a special TGV POS set a new speed record (574.8 km/h) on conventional tracks. The maximum power output was 19.6 MW (26.800 HP) instead of 9.3 MW of a standard TGV POS.
The first Chinese CRRC high-speed trains are also developed and produced with HAUGG cooling.
