PVC trunking is actually a PVC trunking, and it is commonly referred to as trunking, electrical wiring, and trunking. Pvc trunking is equivalent to a circuit protection material, so that the trunk itself has the characteristics of insulation, anti-arc, flame-retardant self-extinguishing and so on, so that even if the electrical leakage of the wire will not be dangerous. The importance of these does not have to be more than Xiaobian. So today Xiao Bian wants to tell us in detail about pvc trunking specifications , installation techniques and precautions. Select the pvc trunking specifications , is the first step to buy high quality pvc trunking.

Pvc trunking specifications pvc trunking installation skills
1, 25mm * 20mm-25mm * 30mm standard trunking, a fixed point should have at least 2 fixed screws and placed horizontally.
2. For slots above the 25mm*30mm standard, there should be at least 3 fixing screws at a fixed point, and it should have a trapezoidal shape, which will spread the stress distribution of the slot.
3, in addition to a fixed point should be drilled two holes per 1m, penetrated with twisted pair, after the completion of the wiring, all the twisted pair bundle up 
4, wall surface mounted PVC trunk, then the slot fixed point spacing is usually 1m, there are two ways to fix are: directly to the cement screw, first hit the plastic expansion tube nail set screw
5, horizontal, hammer trunk wiring method is the same, the difference is nothing more than a horizontal one.
Pvc trunking specifications pvc trunking installation considerations
1. When installing pvc trunking, be careful not to crack the wall, and do not destroy the wall structure. When laying, it should be changed according to the number of guides in the tube. In the same tube, the number of wires should not exceed four. It is forbidden for the wire to fully fill the space in the tube, because it is not conducive to the normal operation of other channels. 
2. The distance between the power line, telephone line and TV line should be greater than fifty centimeters. Pipelines and structures should be fixed. All switches and sockets should have junction boxes installed. If the pipeline bends or is too long, a box of junction boxes should be provided at a certain distance. There must be no wire joints in the pipeline. When the protective tube of the wire is played, the bender tool should be used so that the wires do not have wrinkles. Therefore, it should be configured in accordance with the specifications.
3, in the pvc trunking installation should first install the pipeline, and then wear the wire, so you can avoid the need to change the line in the future, there is no way to traction the wire.
Editor's summary: On the pvc trunking specifications and pvc trunking installation precautions are introduced here, I hope to be helpful to everyone.
