as well as future automobiles to realize innovative growth.

High Speed Train, Pioneering the Era of High Speed Trains

Due to urbanization and higher population density, the demand for and necessity of high speed trains is greater than ever.
Hyundai Motor Group is equipped with world-class competitiveness in the fields of train car designing, manufacturing, and servicing.
We can supply electric trains, high speed trains, and trams to foreign and domestic customers.
Also, we are now expanding the scope of our services to the fields of electronics components,
light maintenance, heavy maintenance, and other vehicle-maintenance related services.
KTX-Sancheon

Hyundai Motor Group succeeded in securing the core technologies for the Korean-type high speed train system of 350km/h. This achievement was followed by the development of the fourth commercial high speed train in the world, KTX-Sancheon, in 2008 and the next generation power distribution type high speed train that can reach about 430km/h (HEMU-430X) in 2012.

Power-distribution Type High Speed Train

In 2016, the company won the contract for the first 250km/h and 320km/h power distribution type high speed train, completing its full-lineup with a power concentration type as well as a power distribution type and developing its competitiveness in terms of high speed trains.

Key Tech

  • Cooling fan units, Coolant tank, Cooling fan units, Heat exchanger, Water cooling pump Heat exchanger

    Development of High Efficiency and Large Capacity
    Water-Cooled Power Control (Converter/Inverter)
    for the First Time in South Korea with Our Own Technology
    The water-cooling system uses ethylene glycol and distilled water as the coolant. This system cools down the heat from the heat exchanger in the coolant tank and sends it to the IGBT stack.

    The water-cooled power control system of Hyundai Motor Group uses the new main power converter that is water-cooled. As a result, the cooling efficiency is higher by about 25% compared to the traditional forced air-cooling system. Also, by completely blocking dusts from coming inside, we can now expect a higher level of maintenance efficiency and reduced failure rate.
