How to choose large-span cable trays?

The selection of large-span cable trays needs to consider the following factors:

1. Span: Choose the appropriate size and type based on the span of the bridge frame. Generally speaking, larger spans require the selection of cable trays with higher strength and stronger load-bearing capacity, while smaller spans can choose more flexible cable trays.  

2. Load: It is necessary to consider the number and weight of cables, as well as possible other loads such as personnel, equipment, etc. If the load is large, it is necessary to choose a bridge with stronger bearing capacity.  

3. Environmental conditions: including factors such as temperature, humidity, corrosion, vibration, etc. If the environmental conditions are harsh, it is necessary to choose a bridge with anti-corrosion, shockproof and other functions to ensure its service life and safety.  

4. Installation and maintenance: It is necessary to consider the difficulty of installing and maintaining the bridge frame, as well as whether it needs to be disassembled and replaced. If installation and maintenance are difficult, it is necessary to choose cable trays that are easy to operate and maintain.  

5. Cost: The cost of cable trays and the expenses for installation and maintenance need to be considered. On the premise of meeting the requirements, reasonable priced cable trays should be selected.  

When choosing a large-span cable tray, it is necessary to consider the comprehensive impact of the above factors. Usually, it is necessary to communicate with professionals and evaluate and select based on specific circumstances.
