How deep should a trench be dug for burying cables with protective sleeves underground?
Thread Content
Standard GB 50168-2018 specifies that when buried directly without a cover, it should be buried 0.7 meters underground; however, it does not state how deep the trench should be when a conduit is used for burial Mine uses a DN50 galvanized pipe and a 50mm2 cable; thanks to everyone in advance{:3_53:}
On-site experience: as long as it is under a muddy floor
So, a rough version can only be produced at the stage of drawing; then the workers will carry out the work based on their experience
Install normally, with the installation depth being no less than 0.7 meters underground
That refers to cables laid underground without protective conduits; the original poster is asking about the situation with protective conduits

The same is true for protective sleeves; generally, there are textual instructions in the drawings
