China Debuts World’s Most Potent Heavy-Duty Electric Locomotive: 10,400 kW Unit Redefines Freight Efficiency

According to reports, China’s first new intelligent heavy-duty electric locomotive was officially rolled off the production line in Zhuzhou, Hunan Province on May 9th, marking another major technological breakthrough in China’s heavy-duty railway transportation equipment sector.

This eight-axle “steel giant” is currently the world’s most powerful permanent magnet direct-drive heavy-duty freight electric locomotive, with a maximum traction power of 10,400 kilowatts per unit.

Compared with traditional electric locomotives with the same number of axles, the single-trip transportation capacity of a single locomotive can be increased by nearly 1,200 tons, and the comprehensive annual transportation capacity can be increased by nearly 280,000 tons.

This locomotive features three globally pioneering technologies. The locomotive employs the world’s first high-power silicon carbide inverter, which can adapt to more complex line grid conditions, making the locomotive traction smoother.

At the same time, this locomotive also incorporates the world’s first high-torque permanent magnet traction motor, which, compared with existing motors, can increase the wheelbase by nearly six times and directly drive the bogie, resulting in higher transmission efficiency and greater environmental friendliness.

Additionally, the locomotive adopts the world’s first high traction force direct-drive bogie as a load-bearing component, equivalent to adding a pair of flexible and powerful “legs” to the locomotive. When in motion, the impact force between the wheel and rail is reduced, and the dynamic performance is further improved.

The locomotive is set to be used for heavy-duty transportation on the second largest corridor of China’s western coal transportation to the east, the Shuohuang Railway, helping to ensure energy supply.
