What skills are needed for PVC trunking installation?

In our decoration project, hydropower transformation is a very important link, which is related to our electricity safety. In the decoration construction project, safety must be the first priority. Today's Water and Electrical Forum mainly talks about the installation of PVC trunking. Let's take a look at what skills are needed for PVC trunking installation. What are our attention during the installation process? Let's take a look.

PVC trunking installation skills:
1. 25mm multiplied by 20mm minus 25mm multiplied by 30mm PVC cable trunking, a fixed point in the installation of PVC cable trunking should have at least two pipe screws and arrange them horizontally.
2. For a 25mm by 30mm or more cable trunking, there should be at least three fixing screws at a fixed point, and it should be trapezoidal.
3. Except for the fixed point, two holes should be drilled every one meter or so, and then passed in with twisted-pair wires. After the wiring is completed, bundle all the twisted-pair wires.
4. If the PVC trunking is installed on the wall surface, the spacing between the fixing points of the trunking is generally one meter, which is divided into nail screws directly into the cement and nail expansion screws loaded with plastic expansion tubes.
5. Hammer trunk or horizontal wiring is the same, one is horizontal and the other is vertical.


Installation precautions for PVC trunking:
1. When installing PVC trunking, be careful not to cause cracks on the wall surface and do not damage the wall structure. The laying time should be changed according to the number of guides in the tube. There should not be more than four wires in the same pipe. It is forbidden for the wires to fill up all the space in the pipe, because this is not conducive to the normal operation of other channels.
2. The distance between the power cord and the telephone line and TV line should be greater than fifty centimeters, and the pipes and structures should be fixed. , All switches and sockets should be installed with junction boxes. If the pipeline is bent or too long, a box of junction boxes should be installed at a certain distance. There should be no wire joints in the pipeline. If the protection tube of the wire is played out, a pipe bending tool should be used so that the wire is not wrinkled, so it must be reasonably configured according to the specifications.
3. When installing and constructing PVC trunking, you should first install the piping, and then wear the wire, so as to avoid the phenomenon that the wire cannot be twitched when the wire needs to be changed in the future.
Pay attention to protect the wires when installing PVC trunking!
