As we all know, furnishing a home with plumbing and electrical wiring is a relatively complex and cumbersome process, so we must be careful and plan when wiring. We usually refer to telephone lines, network lines, cable TV lines and audio lines, etc. as weak wires, while others are called strong wires. When wiring, you need to distinguish between strong and weak electricity, otherwise it will interfere with transmission of information of weak electricity and affect use of household appliances. What should be paid attention to when wiring high and low currents? Let's follow editor to understand relevant content of wiring high and low currents!
Precautions when using high and low current wires
1. Separate strong and weak electricity
In electrical installation, most taboo for us is to store all wires in one place, otherwise it will not only look sloppy, but also greatly affect use of household appliances. When wiring strong and weak currents, national standard is: strong and weak currents must be laid separately, common pipes and boxes are prohibited, and parallel distance between strong and weak currents must be at least 30cm. For practical reasons, distance between strong and weak electricity should be at least 15 cm, and this distance can also ensure that strong electricity will not interfere with weak electricity.
When repairing weak electricity in a home, everyone should know that strong and weak electricity cannot be placed together. It is best to keep a safety distance of 30 cm. This is to ensure that we do not connect and disconnect strong electricity. When electricity is turned on, it will interfere with weak electricity in house. If this is not possible, use aluminum foil as a partition. Remember that when decorating weak electricity, try not to install weak electricity together.
2. Different weak wires should be separated
We just mentioned that strong and weak wires should be separated, we need to pay attention to this point, and different weak wires should also be connected separately. This is because combination of different weak wires will also cause signal interference. To avoid this situation, weak wires such as telephone lines, network cables and TV lines must be run through separate pipes while line is running, and they cannot share same pipe.
3. The wiring is in front and wiring is in back
To consider wire maintenance at a later stage, we need to follow principle of installing piping before threading when wiring. Whether it is a strong wire or a weak wire, we must follow this principle when wiring. This approach not only facilitates subsequent maintenance and wire replacement, but also prevents twitching.wiring.
4. One canvas should not have too many lines
Due to variety and number of wires in building a house, it is inevitable that some wires will be secondary. At present, we must follow principle that one pipe should not exceed four wires. And there should not be a situation where wires fill space in pipe. The utilization rate of ordinary curved tubes is 40% to 50%, and utilization rate of straight pipes can be slightly higher, preferably 50% to 60%. When constructing wiring, if line needs to be turned, we should not make a broken right angle turn, which will directly affect signal strength and cause wire to fail to pass.
5. Do not replace a weak electrical box at usual time, because if you replace an old electrical box, you will change wall again. Thus, new and old walls will easily appear, moreover, if this is done, house will become bumpy and not at all neat and beautiful.
6. Avoid breaking bends at right angles. If during construction and installation of line it is necessary to turn, do not make a right angle turn. This can affect signal strength and cause wires to bend. Therefore, it is best to use large bends and metal angles to bend and connect wires.
7. The wiring is in front and wiring is in back. Regardless of whether it is strong or weak electricity, when installing wiring, you must first follow rules for installing piping, and then threading. This is done to prevent phenomenon of inability to twitch and to facilitate further maintenance.
