Chengdu New Maglev Project
The 3.6-kilometer medium-low speed maglev simulation commercial operation test line built in Chengdu Xinjin has a maximum speed of 160 kilometers per hour, which can meet the traffic needs of the city.
Introduction to the system:
The maximum speed, acceleration ability, climbing ability, turning radius and other indicators of the system have comparative advantages; Compared with other urban rail transit systems, it saves more than 30% of construction and operation maintenance costs.
Traction converter, traction/auxiliary converter, high-voltage electrical box, filter box, auxiliary filter box, battery/charging box, water-cooled control box, etc.
Performance parameters: Traction/auxiliary converter
