On May 10th, it was reported by the media that China's first new intelligent overload electric locomotive officially rolled off the line in Zhuzhou, Hunan on May 9th, marking another significant technological breakthrough in China's heavy-duty railway transport equipment sector.
Dubbed as the "Steel Giant," this eight-axle electric locomotive boasts the world's largest power permanent magnet direct drive technology, with a single locomotive's maximum traction power reaching up to 10,400 kilowatts, making it a leader in the field of heavy-duty freight transport.
Compared to traditional electric locomotives, it demonstrates astonishing transport capabilities, with a single trip capacity increased by nearly 1200 tons, and an annual comprehensive volume boosted by nearly 280,000 tons, bringing revolutionary changes to China's energy transport.
The outstanding performance of the new intelligent overload electric locomotive is attributed to its three global firsts in technology. Firstly, it adopts high-power silicon carbide inverters, enabling the locomotive to adapt to more complex line grid conditions, ensuring smoother traction and stable operation in various harsh environments.
Secondly, the locomotive is equipped with the world's first high-torque permanent magnet traction motor. Compared to existing motors, this innovative design increases the wheelbase by nearly six times, achieving direct drive bogies, enhancing transmission efficiency, and environmental friendliness, injecting new vitality into China's heavy-duty transport sector.
Lastly, the locomotive utilizes the world's first high traction direct drive bogie as its support. This innovative technology adds a pair of flexible and powerful "legs" to the locomotive, reducing the impact between wheels and rails during motion, improving dynamic performance, and ensuring the safety and stability of heavy-duty transport.
After rolling off the line, this locomotive will be used for heavy-duty transport on the second largest channel of China's West-to-East Coal Transportation — the Shuohuang Railway, contributing to energy security.
