Copper core wire, R wire, and national standard wire. Understand these concepts before taking action. Whether the quality of the wire is acceptable is indeed directly related to the circuit safety of home decoration. Many fires and electric shock accidents
are caused by poor quality electrical wiring. Therefore, when decorating a home, wires must not be careless
and you should also pay attention to distinguish them when purchasing.
Electric wires are generally composed of core wires, insulation layers and protective layers. That is to say, the core wire is the core part of the wire
. The common core materials of wires are copper core and aluminum core. Taken together, of course, copper core wires are better than aluminum core wires. Therefore, high-quality household wires on the market are generally copper core wires. However, aluminum cores are much cheaper than copper cores, so beware of buying aluminum cores when buying copper core wires.
The types of household electrical wires are roughly divided into two types: hard wires ( ) and soft wires ( ). The Chinese name for hard wire
Copper core PVC insulated wire is a single concentric hard wire composed of a harder copper wire. When multiple
copper wires are passed through the tube at the same time, due to the higher hardness It is high and difficult to turn, so it is suitable for walking through walls and pipes in a straight way
It is not suitable for turning pipes. The Chinese name of the soft wire is copper core PVC insulated soft sheathed wire. Profile wire
is composed of multiple copper wires of uniform thickness, that is, increasing the number of conductors and reducing the diameter of a single conductor
The diameter of a single conductor is less than millimeters. In this way, the wires can be laid very softly due to their low hardness. The angle is much lower than that of the wires, making it more convenient and faster to thread pipes and wire troughs. It is suitable for turning and threading pipes.
But generally speaking, wires are more expensive than wires. These two lines can be combined and selected according to the different needs of different parts of the home decoration.
We often hear how many square meters of wires refer to the size of the wires. Common sizes include square,
square, square, square, square. The unit of the square of the wire is square millimeters, which refers to the cross-sectional area of the wire
The size of the cross-sectional area can also be selected according to different needs. For example, socket connecting wires can be used. Square-sized ordinary air-conditioning wires should be used. Square-sized water heaters, vertical air-conditioners, refrigerators and other larger-power central air-conditioning should use square-shaped central air conditioners. The entry bus is usually square.
When purchasing wires, you don’t need to choose a brand, but try to choose national standard wires, which means they are used completely in accordance with the country
Non-national standard wires produced according to required standards are often made of recycled miscellaneous copper and defective insulation materials
br/>Although it is cheaper than the national standard wire, the copper core is often thinner and the length is insufficient. Non-marked wires can easily cause short-circuit tripping or burning out of the main power supply, posing huge fire hazards. Therefore, in order to ensure home safety
it is recommended not to be cheap.
There are many effective ways to identify whether a wire is a high-quality national standard wire, including the following.
Take a look at the copper wire and cut it open. If the copper core is high-quality, it should be purple-red and shiny. If it is inferior, it should be purple-black, yellowish or white. Second test: Generally, products with soft hand feel, good fatigue resistance, elastic plastic
or rubber hand feel and no cracks on the wire insulator are high-quality products. 3. Weight: Good quality wires are generally within the weight range specified by the national standard. For example, the weight of a plastic insulated single
copper core wire with a cross-sectional area of square millimeters is .-kg per meter. Four Measurements: Length: Length is the main intuitive method to distinguish products that meet national
standard requirements from fake and inferior products. When purchasing, do not be greedy for cheap prices
Do not purchase wires and cables that do not even have length markings. The length must meet
. The standard requirements are based on meters. The allowable error is meters.
Finally, you can also check the packaging to see if there is a complete certificate. The certificate should include complete information such as specifications, execution scale, rated voltage, length, date, factory name and address. Check whether there is China's national compulsory product certification and production license number. Check whether there is a quality system certification. Check whether the certificate is standardized. Check whether the trademark, specifications, voltage, etc. are printed on the wires. After these steps
you should be able to select wires that meet safety and home decoration requirements.
