PVC-U insulation electrical casing for construction

Circuit transformation should avoid dead wires: no matter how good the quality of the circuit is, it is difficult to guarantee that there will be failures in the future, and the wiring needs to be replaced. At this time, it is very important that the wires buried in the wall can be easily pulled out for replacement. The "dead line" that cannot be moved in the future:

1. Of course, the most important thing is to use threading pipe to embed the thread.

2. The wiring of the circuit should be based on "the shortest distance between the two ends", and the wiring cannot be wound without reason. This will not only cause dead wires, but also increase the investment in power conversion.

3. Don't thread too much thread in a threading tube. You should pull it after threading to see if it can be pulled easily.

4. If there are joints in the line, the buckle panel of the cassette must be left at the joint, which is convenient for future replacement and maintenance.

5. The bending of PVC threaded pipe with pipe diameter less than 25 should use a pipe bender, and no elbow can be added. Right-angled bends will often cause dead lines
