The electrical piping in the ceiling is open, because it does not enter the wall, and it can be seen when the ceiling is opened.
JDG pipe (sleeved set galvanized steel conduit, rigid metal flat conduit for electrical installation) is a kind of latest type of conduit for electrical line protection, and the connecting casing and its metal accessories are composed of screw tightening connection technology.
There is no specification requiring that the electrical piping in the ceiling needs to be made of an independent boom (check GB50303-2011 construction quality acceptance code for building electrical installation projects), and it is possible to use the partition, keel or boom in the ceiling to fix the wire conduit, see page 27 of the national standard drawing or bridge set 03D301-3. >>>More
This depends on the actual situation, generally if it is a heavy lamp, it must be a separate boom, and if it is light, it can not be done.
Flexible metal electrical conduits can be used.
The outer layer of the flexible metal wire protection pipe is hot-dip galvanized steel strip, the middle layer is cold-rolled steel strip, the inner layer is hydro-resistant paper, overlapping rolls are twisted into a spiral, and the outer wall is self-made into a thread buckle. >>>More
