What is an engineering bridge?

Engineering cable tray is a structure used to support and protect electrical wires, typically used for power and communication wiring within buildings. It is made of metal or plastic, with excellent load-bearing capacity and flexibility, and can be bent and twisted as needed. Engineering cable trays are usually installed on walls or ceilings, which can effectively prevent wires from tangled up in a messy manner inside buildings. It can also protect wires from the risk of damage or short circuit, and facilitate maintenance and replacement.

When selecting engineering cable trays, the following factors need to be considered:

1. Load bearing capacity: Choose the appropriate size and material of the cable tray based on the weight of the wires and the expected usage of the building.  

2. Installation requirements: Consider the installation method of the bridge and the required accessories, such as brackets and fixings.  

3. Fire resistance performance: For important facilities or high-rise buildings, the fire resistance performance of cable trays needs to be considered to ensure the safety of wires and equipment in emergency situations such as fires.  

4. Environmental protection: Choose cable trays made of environmentally friendly materials to reduce their impact on the environment.  

Overall, engineering cable trays are a practical tool that can help buildings better manage and protect electrical wires, ensuring the normal operation of power and communication equipment.
