When we decorate our homes, we usually need to carry out circuit modifications. And the current circuit modifications are basically complete modifications. has a problem, that is, the cost of circuit modification is still relatively high, and wires are very critical.
Therefore, many of our friends will choose wires when renovating the circuit. For wires, we have to pay attention to many aspects. For example, the specification and model of the wire, brand type, etc.
What we need to focus on is actually the core of the wire. For example, the cores of commonly used home improvement wires include single-strand hard wires and multi-strand soft wires. So which one is better? In this article, the sister of Qijia Chamber of Commerce will answer the questions about home decoration wire cores.
Is it better to use multi-strand copper core wires or single-strand copper core wires at home?
Whether to use multi-strand wires or single-strand wires for home decoration, this is mainly about the core of the wire.
The so-called multi-strand wire here means that the core of our wire is made of many thin copper wires. The single-strand copper core wire means that the core of our wire is a copper wire, also called a hard wire.
’s personal opinion here is that it is better to use single-strand copper core hard wires in home decoration than multi-strand copper core soft wires. Why does give this view? In fact, the main consideration is the usage characteristics of our home decoration circuits. The specific reasons given are as follows.
① From the perspective of the reliability of wire connection, I personally think that single-strand copper core wire is far better than multi-strand copper core soft wire
I believe that many friends also feel this.
Like the copper-core multi-strand wires we use, it is very easy for the wires to become loose when they are connected. That is to say, the multiple strands of copper wire of the wire are wound together and pulled apart by hand. In fact, this means that its connection is unreliable.
As for the single-strand copper core wire, as long as we wind it according to the requirements, it will be very strong.
Therefore, it is safer and more reliable to use single-strand copper core hard wires for our home decoration wires.
②. For multi-stranded copper core wires, the core of the wire will be oxidized at the connection point of the wire, and an oxide layer will appear.
The specific state of this situation is that the multi-stranded copper core we use The wire connection joints are slowly oxidized and turned black.
In fact, this situation is also a very serious situation. Because the oxidation of the wire will affect the transmission of current, causing a sharp increase in current in this part, the consequence is that the wire joint may heat up, and eventually cause it to be burned.
This is why multi-stranded copper core wires must be reliably insulated and wrapped after being connected.
③. From an installation point of view, multi-strand copper core wires are actually inferior to single-strand copper core wires.
The installation of single-strand copper wires is very simple because its mechanical strength is higher than that of multi-strand concentric wires. Flexible wire, its wire core is just a copper wire.
So when we install the wires, after completing the normal threading, we only need to connect the wires, and the connector is very simple. We only need simple tools to connect wires together easily and reliably.
For multi-stranded wires, the wire connector is more troublesome, and the connection may not be firm multiple times.
④. From the characteristics of home decoration construction, I personally recommend that you choose single-strand copper core hard wires
. Like our home decoration wires, the current common installation method of wires is to lay them hiddenly through pipes. In other words, we must first install the electrical conduit at home. After the electrical conduit is installed, we can thread the wires through the electrical conduit.
You will find that these are threaded by pulling the wire. In fact, during this process, the force on the wire itself is still relatively large.If the quality of the multi-stranded soft wire we use is not up to standard, wire breakage may occur. Broken wires will affect the current carrying capacity of the wire.
For single-strand wires, this problem does not exist.
⑤ From the perspective of later installation of switches and sockets, I personally recommend that you install single-strand wires
After the transformation of our home decoration circuits is completed, switches and socket panels at various locations need to be installed.
For the installation of switches and socket panels, you will find that they are connected by plugging using switches or special terminals behind the socket panel.
The specific operation method is to insert the core of the wire into the terminal block, and then use a screwdriver to tighten it. If we use single-strand copper core hard wire, it is easy to install the wire firmly. But if it is a copper core soft wire, you will find that it is not very strong and can become loose when you pull it by hand.
Therefore, from the perspective of installing switch socket panels, single-strand hard wires are convenient for construction, and are safer and more reliable.
⑥. In terms of cost, I personally recommend that you choose single-strand hard wires
For single-strand copper core hard wires and multi-strand copper core soft wires, if you compare their prices, you will find that single-strand copper Core hard wire is much cheaper than stranded copper core soft wire.
For example, for our more common 2.5 square meters of wire, if one coil is calculated as 100m, then one coil of single-strand copper core hard wire will cost about 300 yuan. But if you buy 2.5 square meters of copper core soft wire, you will find that a plate is at least fifty or sixty yuan more expensive, and the higher one may be hundreds of yuan.
So from this point of view, copper core soft wire also costs a lot of money.
Why do decoration plumbers recommend using soft wires?
In fact, you will find a phenomenon that when renovating many places, plumbers recommend that owners purchase copper core soft wires.
In other words, the water and electricity materials in our home are purchased by ourselves, and the plumber recommends buying multi-strand wires. Why does this happen with
? In fact, the reasons are nothing more than the following three points, which you can understand.
①. The construction of multi-stranded copper core soft wires is more convenient.
Everyone should know about soft wires. They themselves have a certain degree of softness, so during actual construction, threading is easier and the operation is easier. of simplicity. Especially for some simple circuit modifications, such as surface-mounted circuits, it is more appropriate to use soft wires.
The reason why plumbers and electricians ask us to buy soft wires is actually from the perspective of indoor wire construction, which can save a lot of labor.
②. From the perspective of wire installation, plumbers and electricians also recommend that you choose soft wires
because soft wires are indeed easier to operate than hard wires. Whether it is the connection of the wire connector or the connection between the wire and our indoor switch socket panel. Using soft wires is indeed more trouble-free than using hard wires.
means that plumbers use soft wires to connect wires or install our indoor switch operation panels, which can save more labor and require less effort. In fact, for everyone, we can find this problem by doing it ourselves.
However, they did not take into account the weak connection of the cord itself.
③. From the perspective of the current carrying capacity of the wire itself, maybe the plumber is quite reasonable in this regard.
In other words, the current carrying capacity of the copper core soft wire is indeed better than that of the hard wire. This is determined by the characteristics of copper wire. In fact, this is what many friends call the skin effect.
But the point of view given by the sister of the Qi family is that this aspect of our home decoration is almost negligible. In other words, no matter whether we choose a hard wire or a soft wire, the carrying capacity has no impact on home use.
So you don’t need to consider this aspect when choosing wires.
When we decorate our homes, we must choose appropriate wires. Today, the sister of Qijia Chamber of Commerce will focus on answering the questions about the two cores of wires in home decoration. In other words, should we choose hard wires with copper cores or soft wires with multiple strands of copper cores. The final point given by
is that when renovating circuits in your home, it is recommended that you choose single-strand copper core hard wire. Although its current carrying capacity will be slightly lower, it will not affect our use. does have more advantages in terms of installation.
Therefore, when we choose wires, we must consider those that are more suitable for use in our home decoration, rather than necessarily considering the advantages of the wires themselves. This must be clear to everyone.
