The decoration of the new house has many small and large details, and every detail needs to be taken seriously. This is because many decorative details are related to the comfort and safety of the house. However, there are many decorative materials on the market. Therefore, many friends do not know how to choose when choosing materials. Among them, everyone is more entangled. The question of material selection is: Should power cables be flexible wire? Or should I choose a hard line! What is the difference between hard wire and soft wire? Below, I will give you a brief explanation.
Before choosing hard wire or soft wire, we must first know what is hard wire? What kind of wire is a flexible wire?
The so-called flexible wire refers to strands of conductive solid wires with a diameter less than 1mm twisted together, that is, multiple strands of copper wires are twisted together. Therefore, the flexible cord is also called “sheathed cord”. Hard wire refers to a hard wire composed of several thick copper cores. Generally, hard wires of less than 10 square meters are single stranded.
So, what are the advantages and disadvantages of soft and hard wires? The details are as follows.
From the point of view of the service life of the wire, because the hard wire is thicker, it is not easy to oxidize; the flexible wire is composed of multiple thin copper wires, which are easily oxidized by the air, so the service life of the hard wire is much longer than that of the flexible wire From the perspective of the cost of the wire, since the flexible wire is relatively soft, it must be wound many times before use; the hard wire has only one copper wire, which can be passed directly. Therefore, compared with flexible wires, hard aaac conducors have less processing and are much cheaper; from the perspective of current-carrying capacity, flexible wires are composed of multiple strands of copper wire, and their current-carrying capacity is greater than that of a single copper wire. , But when it is suddenly loaded, the capacity of the current-carrying hard wire is greater than the capacity of the flexible wire; therefore, if it is used in general household appliances and the current does not exceed 100 A, single-stranded wire can be used.
2. From the perspective of the working process of the wire, use a soft wire at the connection of the hot tin or iron wire end, otherwise the multi-stranded wire may rise and connect with the next wire, which is very dangerous; and the hardness of the hard wire Very strong, its safety performance is relatively strong, from the perspective of whether it is convenient to repair the wire; although the hard wire is more difficult to replace, it can be completely pulled out of the threaded tube; if necessary, you can also replace the threading; but The cord is different, because the cord is prone to aging and breaks easily, so when the cord is replaced, the wire is likely to be damaged.
Generally, hard wires are more suitable for household use. However, it is worth noting that not all household wires need to use hard wires, and some places are more suitable for flexible wires. Therefore, when choosing wires, you should choose according to the location of the wires and the needs of your own home.
