The Ningbo No. 1 subway project designed and developed by CRRC is a B-type car. The initial, near and long-term use of 6 groups, 4 movements and 2 tows, the initial number of vehicles is 22, a total of 132, the second phase was completed. Added to 39 columns for a total of 234 knots. The car body adopts all-welded drum-shaped aluminum alloy body, the maximum running speed is 80km/h, the construction speed is 90km/h, and the DC1500V overhead contact net is used for flow. The domestically produced traction system adopts the modularized and energy-saving design. Reduce the energy consumption of train operation. At present, in the CRRC, the car-based aircraft in the CRRC has successively received train orders for several subway projects, including Line 2, Line 2, Line 3, and Line 4.
