Why do you use hard wire in decoration? What's the difference between hard and soft?

2020/09/25

Decoration, large and small, there are a lot of details, every detail needs to be treated carefully, to know, many decoration details are related to the comfort and safety of housing. But there are so many decoration materials, many friends often do not know how to choose when choosing materials, and the most common one is to tangle in whether the wires in the new house are soft or hard.

The maintenance electrician recommends the flexible wire to the owner, saying that the flexible wire has good ductility and is convenient for maintenance in the future; and the decoration electrician also recommends the hard wire to the owner, saying that the hard wire is better than the flexible wire, so the single strand wire is better. Now my friends are confused. They are recommended by professionals. Do you want to decorate with hard wire or flexible wire? What is the difference between hard wire and flexible wire?

The following is a detailed explanation for you.

1、 What is a hard wire? What is a flexible wire?
Flexible wire, also known as sheath wire. Generally, it is a conductor made of several strands of conductive solid metal wires less than 1 mm in diameter, i.e. the inner part is twisted with multiple strands of copper wires.
Hard wire, also known as plastic copper wire. Generally, hard wires less than 10 square meters are single stranded wires, which are composed of a few thick copper cores.

2、 Why do you use hard wire in home decoration? In home decoration, choose the advantages and disadvantages of hard wire and flexible wire?
1. In terms of service life, hard wire is not easy to be oxidized due to its thick wire; while flexible wire is composed of multiple strands of fine copper wire, which is easy to be oxidized by air. So the service life of hard wire is obviously longer than that of flexible wire.
2. From the price point of view, because the flexible wire is relatively soft, it can only be used after many times of winding; while the hard wire has only one copper wire, which can be directly put through. Therefore, the hard wire process is less than the flexible wire, and the price is much cheaper.
3. From the point of view of carrying capacity, the flexible wire is made of many strands of copper wire, so it is larger in the current carrying capacity than the hard wire of single copper wire, but in the sudden load, the bearing capacity of the hard wire is stronger than that of the flexible wire. However, the general household, the current basically does not exceed 100A, with a single strand can.
4. From the safety point of view, the standard use method of flexible wire is to iron tin on the joint or press the wire nose when wiring, otherwise the multi stranded wire may be cocked up and connected with the adjacent conductor, which may cause danger. The hardness of hard wire is strong, and the safety is also relatively strong.
5. From the convenience point of view, although the hard wire is more laborious when replacing the wire, it can ensure that it can be pulled out completely from the threading pipe smoothly. If necessary, it can replace the threading wire and pull the new wire together. But the flexible cord is easy to break after aging, and it is likely to break the wire when changing the wire.

3、 Where are hard wire and flexible wire used?
Due to the weak tension resistance, corrosion resistance, fatigue resistance and low recovery rate of waste products, flexible wires are suitable for the connection of equipment wiring.
Compared with soft wire, hard wire is cheaper, stronger in tension resistance, corrosion resistance, fatigue resistance and waste recovery rate. Therefore, hard wire is generally used in power system, that is, buried wall, buried, as the main line.
It can be seen that there is no difference between the two, only who is more suitable for which position. So we can choose hard line or soft line according to the position of decoration. In general, it is recommended to give priority to hard wire, which has better oxidation resistance and longer service life. However, if the circuit turns too much during construction, flexible wire can be selected to make it easier to wear.
