Anonymous users2024-01-24Whether you use a flame retardant PVC corrugated hose or a metal hose to guide the conductor depends on your application. For the wiring of residential buildings, because the load current on the conductor is small and the electromagnetic impact on the surrounding space equipment is not large, the flame-retardant PVC corrugated hose wiring can be used. For some special occasions such as computer rooms, communication rooms and other places, in order not to affect the normal operation of adjacent equipment and signal cables, metal pipes are needed for wiring.
Therefore, the living room of the house is wired with flame-retardant PVC corrugated hose.
FYI.
It must be separated, the reason is (example piping): 1. The concealment time of the piping in the wall and the piping in the ceiling is different; 2. The piping practices are different; 3. The inspection content of concealed engineering is different. It is better to separate, otherwise the construction process will not intersect.
According to the "Code for Construction and Acceptance of Socketed Tight Steel Conduit Wire Pipeline", there is no need to brush conductive paste.
Line direction, wire diameter, load size, whether there are joints, joint location.
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
