The cable for urban rail transit refers to the cable used in the urban rail transit system, mainly including power cable, communication cable, signal cable, etc. These cables play a vital role in the urban rail transit system, providing power and signal transmission for the operation of trains.
Urban rail transit cable has the following characteristics:
1. High reliability: The urban rail transit system has very high reliability requirements for the cable, because once the cable fails, it may lead to train suspension and affect the normal operation of the entire traffic system. Therefore, the cable for urban rail transit must have high reliability.
2. High voltage level: Because the urban rail transit system needs to transmit a large amount of power, the voltage level of the cable is also relatively high. For example, in China, the voltage level of urban rail transit cables is usually above 10kV.
3. Anti-interference ability: there are various electromagnetic interference in the urban rail transit system environment, so the cable must have a strong anti-interference ability to ensure the accuracy of signal transmission.
4. Waterproof performance: Urban rail transit systems usually operate on underground or elevated lines, so the cable must have good waterproof performance to prevent moisture from entering the cable interior, resulting in failure.

In urban rail transit systems, cables are usually used in the following aspects:
1. Power transmission: cables provide power for trains and lighting.
2. Signal transmission: The cable is used to transmit the train's operating signals and control signals to ensure the safety and punctuality of the train's operation.
3. Communication system: The cable is used to establish the communication network of the urban rail transit system, including the communication between the train and the ground, and the communication within the train.
4. Automation system: Cable is used for automatic control of urban rail transit system, including automatic train control, automatic station control, etc.
In short, urban rail transit cables play a vital role in the urban rail transit system, they provide power and signal transmission for the operation of trains, and ensure the normal operation of the entire traffic system.
