Can building lighting lines go to a layer of leveling?
I feel should be possible, because PVC is a halogenated hydrocarbon polymer, can not be ignited.
The rules do not allow the fire pipe to wear PVC pipe, if the fire will soon fire the PVC pipe fire line burned, so that the emergency power supply simply can not play a role. In accordance with the provisions of the fire line are generally galvanized pipe, in accordance with the provisions of the fire line can be used when the JDG (tightening tube), the laying of the line or ceiling laying must use steel pipe, joints to use the threaded connection, paint. The rules are so prescribed, but many people do not follow the rules in order to save costs. Only for the landlord reference.
We here is an eight-storey office building, is a fire, ask the electrical construction can use PVC wire tube it? Non-emergency lighting with the line can be, or use the steel bar.
