Lay dark lines must be insulated to wrap the wires in the conduit. The wire should be made of a slightly thicker line, preferably a glue line, and it is more resistant to corrosion. The following small series for everyone to introduce dark-line decoration related knowledge.
What is the dark line?
The dark line means: The strong/weak wire buried in the wire slot is usually wrapped in the wire tube. The rules for the use of strong electricity are 1.5 mm2 insulated copper wire for cross-sections of lighting wires, 2.5 mm2 insulated copper wire for ordinary sockets, and 4 squares for air-conditioned wires. Otherwise, when using air conditioners, it is prone to overheating and softening. The best use of cooked glue line, strong corrosion resistance. The wire tube generally uses 4 points PVC pipe on it.
Dark line laying method
(1) Select and determine the location of lamps, sockets, switches, etc., according to the production of the effect map and the design drawings of the concrete construction drawings. Then determine the location of the laying of the wires, the position through the walls and the floor, and the start, corner, branch, and terminal. Point, fixed position of insulator or slot board.
(2) Excavate the wall groove according to the direction of the wire, and the width and depth of the groove should be able to bury the wire tube. In the hole through the wall to carefully bend the wire, so that it can still be threaded after the inside, with a special rolling head or saddle wire to the wire tube fixed to the wall.
(3) There are sockets, switch positions pre-embedded plastic expansion tube or a good wood wedge. The disadvantage of this method is that the socket and switch protrude from the wall; it is now popular to bury the socket and the junction box of the switch in the wall, only exposing the panel of the socket and the switch, so that it is more beautiful and neat.
(4) Threading, the normal practice is to pass the wire first, and then pull the wire. In the home decoration, the electric wire can be directly put into the jacket pipe, but it is difficult to pass through at the turning place. Therefore, the electric wire is generally put in place while the plastic pipe is installed, or a lead wire is preliminarily put in the plastic pipe.
(5) Power on, wait for all the wires to wear well, and connect with the switch, socket, light fixture and try to energize. After the wiring is correct, the open wall will be filled with cement mortar.
Precautions
The dark line means that the wires are concealed, so that insulation must be done, and the wires must be larger to pay attention to the construction drawings of the reserved lines. It is better to use PVC pipe sleeves, and the best use of the copper cores of the brand is the dark lines. The line is 2.5mm, the socket is 4mm, and the power source is 6mm.
Concealed to pay attention to the heavy wall Do not play too much trunking. The wet place should pay attention to waterproof, wiring place must be wrapped with PVC tape and then wrapped with insulating tape again. It's too much of it, or go find a professional electrician to do it for you. Pay attention to safety. The antenna should be grounded. There should be an earth leakage protector in the house from the main power box. After entering the house, install a small electric box and open it (for mounting a few to see yourself). A general lighting, a socket, air-conditioning and other high-power electrical appliances best one, stay in a standby. Out of these good buy lines also buy red, yellow, green, blue, as well as two-color lines, in fact, no difference, mainly to facilitate future maintenance.
There are two ways to use the dark line. One is to bury the line pipe (usually a PVC pipe) in the wall and the floor when building a house, and then pipe the pipe. If there is no pre-embedded pipe, or if the location of the local electrical equipment is not suitable and it needs to be remodeled, then the wall should be slotted. The slotting tool is a hammer or a chisel. The depth and width of the groove are slightly larger than the diameter of the wire tube. After the wire is completed, it is filled with cement. As for the fact that your wall is not painted, you still have to groove, but you can only light it slightly because the thickness of your stucco layer cannot exceed the diameter of the wire tube (at least 16mm). Do not cut corners and use electric mortar directly on the wall.
