Wires and cables are electrical products for transmission of electricity and information. It is widely used in modern electrical products. The broad wire and cables are also referred to as cables for abbreviation.We are usually inseparable from the electric wire when we use electricity. The wire is an important object that needs to be purchased with caution in family decoration.While ensuring our electricity safety, high -quality wire and cable can also conduct cable transmission high efficiency.Therefore, when installing the wires, we must also understand some attention and install misunderstandings. In the later period, we must pay attention to the maintenance of the wires.
What should I pay attention to when installing the wire
1. The correct connection method
In the process of laying a wire, try to avoid connections as much as possible, because the connection is often the most prone to a large resistance, resulting in the heat of the wires. If the connector cannot be avoided, then the external insulating adhesive cloth is tight.
2. Choose a reasonable installation form
You can choose two different forms: bright and dark installation in the installation of indoor wires. The light -fitting is laid along the wall and the surface of the ceiling. Pay attention to the familys self -installation.The wire is fixed.Dark installation refers to the wires that are laid in the wall or the ceiling. For safety reasons, the dark installation must be operated by professional personnel.
3. Use ground wire correctly
For electrical appliances that need to use three -phase plugs such as washing machines and refrigerators, reliable ground wires must be installed.
Wire installation misunderstanding
Misunderstanding 1: Strong and weak electricity co -tube
Storage all the wires together, the power cord, network cable, telephone line, etc. are placed in the same base, so that the lines will be disturbed, resulting in unstable signal.It will also launch a hidden danger for fires in the home.Strong and weak electricity should be separated. It is strictly forbidden to share a tube and a bottom box. The parallel distance between the strong electric line cannot be less than 3cm. It is best to be 50cm. The cross must be a straight corner.
Misunderstanding 2: Repeat wiring
Each wire uses a pipeline, and a lot of pipelines are buried inside the wall. When it is maintained in the future, it is difficult to find the location of the problem pipeline.Generally speaking, the line should be made into a "live line", and the same direction wires are placed in a pipe without exceeding the pipeline capacity.This is both economical and avoiding the trouble of maintenance in the future.
Misunderstanding 3: The wire does not be buried without the tube
The wires are not available for insulating tube, and the joints are directly outside, which can easily cause hidden safety hazards.The laying of the wires should be clearly standardized that there must be insulation sleeve protection outside the wire, and the joints cannot be outside.Therefore, during the construction supervision, the owner must supervise whether the construction party will be constructed as required.
Misunderstanding 4: Socket wires are installed at random
The power wire must be cross -section of the copper wire.If you live in an old house, you must replace the original aluminum line with copper thread.Because the aluminum line is very easy to oxidize, it is easy to fire at the joint.Remember to follow the principles of "the line in the fire into the switch, the zero line into the lamp head" when the wiring, and set the leakage protection device on the socket.
Maintenance of wires
1. Avoid moisture, heating, corroding or injury, try to make these unhealthy environments in principle when using the wires.
2. After using the wire for a period of time, check the wires regularly. If the problem is found, it should be replaced within the first time.
3. Do not let the wires overload to avoid accidents.
4. Check out the use of electrical and lines at home from time to time, find problems, and timely maintain and repair.
5. For some lines that are installed in the old -fashioned building line or disappointed for a long time, you must check whether the wires are aging. If the problem is found, the electrician should be asked to repair immediately.
6. Pay special attention to the routes that are easily soaked in floods. If necessary, you can ask the electrician to migrate the line and protect it with elevated and moisture -proof measures.
7. If the power is stopped, the power should be cut off immediately. Please check the cause of the electrician and send a special person to take care of it.
