Needless to say, cable trays are naturally expensive. Advantages and disadvantages should be analyzed based on specific issues. For example: in the case of a combustible gas leak, its density is greater than that of air. It is advisable to use overhead cable trays for installation, in order to avoid flammable gases. Instead, use a cable trench. Look for relevant books or materials.

Cable trenches take up little space and are easy to conceal, but construction is difficult in areas with crisscrossing underground pipelines and numerous drainage ditches; they are also not suitable for places where explosive gases are denser than air.
The cost of cable trays is relatively low, but they are suitable for power supply in the lower floors. Generally, a combination of cable trays and trunking is used; one foreign-funded project required that trunking also be installed within the cable trays, as a means of protecting the cables. Do everyone agree? It always seems a bit strange!
Sand-filled cable trenches can be used in explosion-proof areas. . It’s a problem to use cable trays for heat dissipation in cable trenches. .
The selection of cable trenches or cable trays should be determined based on local conditions, in accordance with the design specifications for power cables. Underground cable trenches are prone to water ingress and difficult to inspect; cable trays are always visible but tend to intersect with overhead pipelines or buildings, making them susceptible to environmental influences.
Cable trays are more expensive than cable trenches, but they have different applications; the choice depends on the specific conditions on site.
There are many rats in the cable trench :lol
The cable tray is visible, while the groove is invisible; the groove is cheaper.
