Should we use the bright line or the dark line in the hydropower renovation? In fact, now the dark line is basically taken, which is not only beautiful, but also more standardized. Of course, if the dark wire is installed, the price will be more expensive than the bright wire. So how do you go through the dark line? What are the steps? Let's take a look!
[Dark line installation steps]
1. Design the drawings according to the renderings and specific construction drawings, and select and determine the location of lamps, sockets, switches, etc., and then determine the location of the wiring, the location of the wall and the roof, and also determine the start, corner, branch, terminal For the location of the points, fix them with insulators or slot plates.
2. Dig the wall slot according to the direction of the wire, and the width and depth of the slot should be able to install the wire tube. When making the hole for the wall, pay attention to carefully bend the wire tube, so that the inside of the sheathed tube can still be threaded, and fix the sheathed tube on the wall with a special rolling head or a riding nail.
3. If you want to install sockets and switches, first drill holes in the plastic expansion pipes or wooden wedges, but the disadvantage of this method is that the sockets and switches protrude from the wall; and the wiring of sockets and switches is popular nowadays The boxes are buried in the wall, only the panels of the sockets and switches are exposed, which is beautiful and tidy.
4. The normal method of threading is to first use a steel wire to pass through the sheath tube, and then pull the wire in. You can put the wire directly into the sheath tube in the home improvement, but it is not easy to wear at the corner, so it is generally placed at the same time as the plastic tube is placed, or the lead wire is put through the tube first.
5. After all the wires are put through, connect the switch, socket and lamp to test the power, and prove that the wiring is correct, then use the cement mortar to make up the cut wall.
ã€Notice for concealed installation】
1. The power cord must have a sheath tube and cannot be buried directly in the groove.
2. The sheath tube should be horizontal and vertical, and the elbow should be treated with an elbow sheath tube.
3. Different circuits, voltages, alternating current, and direct current cannot be worn in the same tube.
4. The cross-sectional area of ​​the power cord cannot exceed 40% of the line pipe. Generally, a pipe with a diameter of 15 mm can only wear 4 wires with a cross-sectional area of ​​2.5 square mm.
5. The power cord should use single-core copper wire.
6. The line pipe should be buried 15 mm deep on the wall surface.
7. There can be no joints in the wires in the tube, and the tube must be connected with a joint and fixed with a special adhesive.
8. The rated voltage of the wire insulation in the conduit should not be lower than 500 volts.
9. Change the lines as little as possible, let alone the large-area full-room changes. If there are large-area changes, the lines must be rearranged and the original lines abandoned.
The above are the steps and precautions for you to share the dark line for you. The water and electricity wiring must be paid attention to to avoid mistakes and safety hazards!

Steel can be easily fabricated and produced massively. Steel sections
can be produced off-site at shop floors and then assembled onsite. This
saves time and increases the efficiency of the overall construction
process.
