1.Wires buried in the wall need to wearPVCLineTube?
I always feel that the wall is very strong, and the wires buried inside are completely safe and reliable. I also put the wires inPVCLineIn the tube. Isn't that unnecessary? So I stopped the electrician on the spot. I don't need to put the wires and pipes in the PVC pipe, just put it in the groove and seal the wall. But I didn't expect that because of this decision, some security risks were buried.
After living in the house for two years, the once circuit automatically cut off power. At first I thought there was something wrong with the air switch, so I asked the electrician to check it. After checking, it turned out that there was a problem with the wires buried in the wall. The electrician had to chisel through the walls to replace the wires. When the electrician cut the wall, he understood the problem. The reason is that the wires in the house are not worn.PVCLineTube, too hurt the wire. After listening to the electrician's analysis, I suddenly realized.
It turns out that during the wiring process, the wires may be pulled or scratched, resulting in damage to the insulation, and the copper wires inside naturally lose the protective layer. In addition, the wire does not penetrate the PVC pipe and is directly buried under the cement, so the silicate contained in the cement may corrode the wire and cause power failure.
The electrician told me that the wires must go throughPVCLineTube, and then buried in the wall, because this can ensure the safety of wiring, as well as the role of flame retardant. In case the wire is short-circuited in the future, causing a fire inside the wire, the wire pipe can effectively prevent the fire from spreading. On the contrary, if the wires are not installed, the consequences may be very serious.
After hearing what the master said, it turned out to have played such a big role. The wire passed through the conduit and was buried in the wall. Moreover, the state also has clear regulations requiring pipelines to be completed before construction. Therefore, when people decorate in the future, whether it is the wire to the top or to the ground, remember to do a good job of threading. After all, electricity safety must not be sloppy, so that they can live at ease.
Therefore, before entering the wall, do not forget to put the wire into the pipe. Of course, in order for the wire to play the above-mentioned protective role after entering the pipeline, the following points need to be done:First, it must be guaranteed.pvcLineThe quality of the tube, especially in terms of flame retardancy. Second, when entering the tube, the wire should not be completely blocked, and a certain space should be left for easy extraction and inspection. Third,pvcLineThe tube has a certain thickness, too thin, and its protection will definitely be affected.
