Urban rail transit has very strict requirements for FRP cable trays
With the continuous development of urban rail transit, FRP cable tray, as an important facility and equipment, plays an increasingly important role in the rail transit system. However, due to the strict requirements of urban rail transit for safety, reliability and efficiency, the requirements for FRP cable tray have also increased accordingly.
First of all, FRP cable tray needs to have high strength and durability. The operating environment of urban rail transit is complex and changeable, and the bridge needs to withstand various loads and stresses, and at the same time, it also needs to withstand long-term use and testing. Therefore, the bridge must have high strength and durability to ensure that it can operate stably for a long time in various environments.
Secondly, FRP cable tray needs to have excellent electrical properties. There are a large number of power equipment and communication equipment in the urban rail transit system, and the bridge, as a support and protection facility for power and communication lines, needs to have excellent electrical performance, including low insulation resistance and high withstand voltage performance.
Third, FRP cable tray needs to have good fire performance. Fire accidents in urban rail transit can cause serious loss of life** and property. Therefore, the FRP cable tray needs to have good fire performance, be able to maintain a certain stability in the fire, and reduce the impact of the fire on the entire rail transit system as much as possible.
Fourth, FRP cable tray needs to have good environmental performance. As an important part of urban transportation, urban rail transit needs to reduce its impact on the environment as much as possible. Therefore, FRP cable tray needs to have good environmental performance, including lower noise, lower radiation, etc.
Finally, FRP cable tray needs to have high safety performance. Urban rail transit runs at a fast speed and has a large passenger flow, so the safety performance of the bridge is crucial. The bridge needs to have high impact resistance, wear resistance, etc., to ensure the safety of passengers.
In short, urban rail transit has very strict requirements for FRP cable tray, which not only needs to have high strength and durability, excellent electrical properties, good fire performance and environmental protection performance, but also needs to have high safety performance. Only by meeting these requirements can we ensure the safe, reliable and efficient operation of urban rail transit.
