- 产品介绍
The entire project of Kunming Metro Line 1 designed and developed by CRRC is equipped with 40 columns and 6 sections (4 sections of trains and 2 sections of trailers). It is completely tailored according to the local geographical environment and climate of Kunming. The train has a speed of 100 kilometers per hour and a maximum passenger capacity of 1870. The whole vehicle adopts high-strength all-welded aluminum alloy body technology. The traction system, network control system and drive system adopt domestically produced equipment. The interior lighting uses LED energy-saving technology. The train is The first high-altitude subway in China. The front part of the train adopts a buffer, a crusher, an anti-climbing device, and a deformation zone. The four-stage energy absorption collision avoidance safety design is called the five-star safety of the metro vehicle in China. At present, the CRRC car plant in Kunming has successively received train orders for several subway projects such as Line 3, Line 6, Line 4 and Line 5.
