Shijiazhuang Line 1 Rail Vehicles
The Phase I project of Shijiazhuang Metro Line 1 is the backbone line of the east-west direction of the Shishi Rail Transit, with a total length of about 23.9 kilometers, all of which are underground lines. There are a total of 21 stations, with an average station spacing of 1.215 kilometers; The vehicle adopts an A-type vehicle. Main considerations: The interior of the vehicle is a closed space with high pedestrian flow, and the overall comprehensive maintenance cycle of the rail vehicle is once every 15 years, except for special reasons. It is necessary to improve the cleanliness of the pipeline as much as possible and minimize the bacterial pollution caused by the air conditioning system.
design goal
1. Clean and hygienic;
2. Reduce load;
3. Fire safety;
4. Quiet and safe.
P3 pipe solution
1. The air duct material does not absorb water, and the inner wall is made of edible grade smooth aluminum foil, which does not accumulate dust or bacteria, ensuring air quality and inhibiting bacterial nourishment;
2. The pipeline is lightweight and weighs only 1.2 kilograms per square meter (compared to the traditional aluminum plate and insulated air duct used in rail vehicles, our air duct weighs less than half of it, reducing the load on the vehicle body);
3. According to the German DIN5510 fire detection, the smoke toxicity detection value FED is only 0.02 (standard value is 1).
