What are the precautions for strong and weak wiring? What are the construction specifications for strong and weak wiring?

if you want to use electricity for indoor decoration, you naturally need to wire, which can be divided into strong current and weak current. What are the precautions for wiring strong current and weak current? Because the safety of electricity consumption is very important, some owners are also worried that the wires are not laid properly, which will affect the safety of electricity consumption in the future. What are the construction specifications for strong and weak wiring?

1. What are the precautions for wiring of strong and weak current

1. Separate strong and weak current

In wiring, we are most afraid to store all wires in one place, which will look messy and have a great impact on the use of household appliances. When wiring strong and weak current, the national standard is that strong and weak current should be routed separately, and it is forbidden to use * * * boxes, and the parallel distance between lines between strong and weak current should not be less than 3cm. Considering the actual situation, the distance between strong and weak electricity should be at least 15 cm, which can also ensure that strong electricity will not interfere with weak electricity.

2. Different weak wires should be separated

Just now, we mentioned that strong wires and weak wires should be separated, so we need to pay special attention to this point, and different weak wires also need to be wired separately. This is because different weak wires together can also cause signal interference. In order to avoid this situation, weak wires such as telephone lines, network lines and TV lines must be threaded separately during line operation, and the same tube cannot be used.

3. Route the wiring before the wiring

For the sake of wire maintenance in the later period, the principle of installing the pipeline before threading should be followed at the beginning of wiring, and both strong wires and weak wires should be routed according to this principle. This approach not only facilitates the later maintenance and replacement of wires, but also prevents the wires from twitching.

4. There should not be too many wires in the same pipe

Because there are many types and quantities of wires in home improvement construction, some wires will inevitably have the phenomenon of * * * pipes. At this time, we need to follow the principle that one pipe cannot exceed four wires. Moreover, there must never be a situation in which wires fill up the space in the pipe. For example, the utilization rate of elbow pipes is between 4% and 5%, and straight pipes can be slightly higher, preferably between 5% and 6%. In the construction route, if the line needs to turn, we must not turn right angle in a broken way, which will directly affect the signal strength and cause the conductor to be unable to pass through.

second, what are the construction specifications for strong and weak current wiring?

1. Strong and weak current lines need to be wired separately.

A big taboo in circuit transformation is that the construction team can put all the lines together for the convenience of construction. The consequence of this is that there will be interference between lines, which will lead to unstable signals and leave a fire hazard. Therefore, when the circuit is reformed, the strong and weak current should be routed separately. It is forbidden to use a tube and a bottom box for the strong and weak current. The parallel spacing of the strong current lines should not be less than 3cm, but 5cm, and the crossing must be at right angles.

2. Laying pipes before wiring

Weak current construction, like strong current construction, should install pipes before threading, so as to avoid the situation that wires cannot twitch when changing wires in the future.

3. Steel pipes should be used for weak current

Steel pipes or rigid PVC pipes should be used for weak current threading pipes. PVC pipes are relatively cheap and commonly used, but their signal shielding effect is not as good as that of copper pipes. Therefore, if there are local interference sources in the line and the minimum clear distance cannot be met, steel pipes should be used as threading pipes.

4. Avoid too many lines in the same pipe

When laying, it should vary according to the number of wires in the pipe. In the same pipe, there should not be more than four wires. It is forbidden for wires to occupy all the space in the pipe. The utilization rate of straight pipe diameter should be 5%~6%, and the utilization rate of elbow pipe diameter should be 4%~5%.

5. Different weak wires should be routed separately.

In order to avoid signal interference, telephone lines, network lines, cable TV lines and other weak electricity should be routed separately in circuit construction, not in the same tube.

6. Avoid taking a broken right-angle bend

When wiring, be careful not to take a straight broken right-angle turn of the conduit, which will easily lead to the line not passing through and have a great influence on the signal, so use a big bend to connect.

what are the precautions for strong and weak current wiring? Specific electricity matters need professional master to pay attention, and the owner can find a regular master to complete them. What are the construction specifications for strong and weak current wiring? Be sure to pay attention to the qualification and ability of electrician, or all kinds of troubles will easily occur if the wires are not laid well.
