There are many details in the decoration of a new house, no matter how big or small, every detail needs to be carefully considered. You know, a lot of decorating details have to do with the comfort and safety of the home. But with so many decoration materials, many friends often don't know how to choose when choosing materials. The most common thing is to be entangled in whether the wires of the new house are soft or hard. The maintenance electrician recommended a soft wire to the owner, saying that the soft wire has good extension performance and will be convenient for maintenance in the future; the decoration electrician recommended a hard wire to the owner, saying that the hard wire is better than the flexible wire, so the single wire is better. This friend is confused, is it recommended by a professional, so hard line or soft line decoration? What is the difference between hard wire and soft wire? The small side below will give you a detailed explanation. 1. What is a hard line? What is a cord? Soft wire, also known as sheathed wire. Generally, it is a wire made of multiple conductive solid metal wires with a diameter of less than 1mm, that is, the inside is wrapped with multiple strands of copper wire. Hard wire, also known as plastic copper wire. Generally speaking, the hard wire under 10 square meters is a single-strand wire, which is composed of several thick copper cores. Second, the advantages and disadvantages of hard line and soft line. 1. From the perspective of service life, since the hard wire is thicker, it is not easy to oxidize; the soft wire is composed of multiple thin copper wires, which is easily oxidized by air. Therefore, the service life of hard wire is significantly longer than that of soft wire. 2. From the price point of view, because the wire of the soft wire is relatively soft, it can only be used for multiple windings; the hard wire has only one copper wire, which can be passed through directly. Therefore, the process of hard wire is less than that of soft wire, and the price is relatively much cheaper. 3. From the load point of view, the soft wire is wound with multiple strands of copper wire, so the load flow is larger than that of the hard wire of the single-strand copper wire, but when the load is suddenly applied, the bearing capacity of the hard wire is higher than that of the soft wire. powerful. But at home, the current basically does not exceed 100A, and it can be single strand. 4. From a safety point of view, the standard use of flexible wires is to tin or crimp the connectors when wiring, otherwise the multi-strand wires may tilt upward and connect with the conductors next to them, causing danger. The hard line has strong hardness and strong safety. 5. From the point of view of convenience, although the hard wire is laborious when replacing the wire, it can ensure that the complete wire can be pulled out smoothly from the threading tube. You can also replace the wires if necessary, pulling the new wires together. The soft wire is easy to break after aging, and it may be accidentally broken when changing the wire. 3. Where hard wires and soft wires are used. Because of its weak tensile strength, weak corrosion resistance, strong fatigue resistance, and low recycling rate of waste products, flexible wires are suitable for connection during equipment wiring. Compared with soft wires, hard wires are less expensive, have higher tensile strength, are more resistant to corrosion, are less resistant to fatigue, and have higher waste recycling rates. Therefore, the power system generally uses hard lines, that is, buried walls and buried ground as the main line. It can be seen that there is no difference between the two, who is bad, only who is more suitable for which position. So you can choose hard or soft wire depending on where the trim is placed. It is generally recommended to give priority to hard wires, so that the anti-oxidation performance is better and the service life is longer; but in construction, if the circuit has too many turns, you can also choose soft wires, which are easier to wear. .
