Cooler! China's new high-tech high-speed rail car debut localization rate of 90%

The high-speed rail is already one of China's most eye-catching signs to the world. In order to better improve related technologies, the new high-tech high-speed rail car is now unveiled.

According to the China Youth Daily, at 10:00 this morning, CRH5G technology upgrading EMUs produced by China Railway Changchun Railway Vehicle Co., Ltd. arrived at the Xi’an EMU segment. This was the first time that the EMUs of this model appeared in China.

The biggest feature of CRH5G's new high-tech high-speed rail car is that it is equipped with the first domestic train network control system with completely independent intellectual property rights and the train traction system with completely independent intellectual property rights, and the localization rate is over 90%.

In addition, according to the characteristics of the northwestern climate, CRH5G car cabins emphasize the characteristics of alpine wind resistance, reduce the vehicle's center of gravity, further reduce the air resistance during high-speed operation, and increase the body width by 10 cm. WiFi is also reserved. interface.

The new CRH5G is designed to operate at a speed of 250Km/h. More specifically, the CRH5G EMU activates the sanding device in response to the reduced friction coefficient between the rails and the wheels during rain and snow and the possible idle and coasting of the wheels. The sand particles are sprayed on the track to increase the friction between the track and the wheels, which is extremely suitable for the bad weather on the Baolan high-speed rail.
