Is it really necessary for cables to run in cable trays? Is direct pipe installation in compliance with the standards?
Thread Content
There are 8 instrument cables in the tank area; is it necessary to use cable trays? Can steel pipes be laid directly on the ground? How can one proceed in a way that is both compliant with regulations and reasonable? I hope an expert can help answer this. Thank you very much
Or it can be elevated; it’s easy for water to get in if it’s at ground level

As long as the site conditions permit, for loading cabinet rooms dedicated to tank areas where there are not many instrument points and no beam structures available for use as cable tray supports, burial is usually the preferred option. When burying such structures, it is necessary to ensure proper waterproofing; following the standard construction guidelines for burials will generally suffice.
Piping is an option, but I personally think burying it makes future maintenance less convenient; there’s no need to use cable trays for small quantities of cables
It can be run through a tube, but if the cable is too long, it’s difficult to pass it through the tube.
How to move around in the tank area without pipes? Generally, pipe trenches are used for direct burial in tank areas.
I’ve never heard that waterproofing is necessary; it’s not about renovating a toilet, but about laying pipes.
I haven’t heard of any standards regarding the burial of cable protection pipes underground; could you provide such a standard? Tell me how deep to bury it, how to ensure waterproofing, and how to provide compressive strength.
Everyone, please keep pinching~~~~:lol
≥Minimum vertical burial distance: Below the permafrost layer in cold regions; there are minimum clearance requirements with respect to building foundations and electrical cables. There are also minimum distances required when running parallel to or intersecting with other pipes. When passing through roads, protective pipes must be used, and these pipes need to be waterproof. There is a minimum thickness requirement for the soil layer applied. I can’t remember exactly how many millimeters it is, but there definitely is such a requirement. Just because you haven’t heard of it doesn’t mean it doesn’t exist – have you learned something new?
