Where are trough-type cable trays generally used?

Trough type cable tray is a closed type of cable tray, usually used for laying electrical circuits, especially in situations where electrical circuits need to be protected and external factors need to be prevented from affecting them. It is often used for ceilings, walls, or floors inside buildings, as well as outdoor high-altitude installations. Specifically, trough type cable trays are suitable for the following scenarios:

1. Indoor ceiling: Trough type cable trays can be used for laying electrical circuits on indoor ceilings, such as electrical circuits for ceilings, air conditioning circuits, etc.  

2. Indoor walls: When electrical circuits need to be laid on indoor walls, trough type cable trays can provide a closed and safe way.  

3. Indoor flooring: In some scenarios where it is necessary to prevent people from stepping on or external factors from damaging electrical circuits, such as sidewalks, shopping malls, stations, and other public areas, trough type cable trays can be used for flooring.  

4. Outdoor installation: In high-altitude outdoor installation, trough type cable trays can provide a closed and safe way of laying electrical lines, such as crossing highways, railways, etc.  

In general, trough type cable trays are mainly used to protect electrical circuits, provide safe and reliable wiring methods, and are suitable for various scenarios, including indoor and outdoor, walls and floors.
