What is light ceiling piping?

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.

In the current design, metal conduits are generally used for the lighting piping in the ceiling, and JDG tight conduit and welded steel pipe are generally used for the lighting project. Originally, there were also designs that used PVC flame retardant pipes, but there were not many of them laid in the ceiling. Generally, residential lighting is also designed as PVC flame retardant pipes, but generally not laid in the ceiling, directly laid in the wall and roof dark pipes.

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.

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
