Can household copper wires be burned by fire, and why are wires burned

Depending on how big your copper wire is, if the wire inside the wire can be burned.

Poor quality can, *** can also, it's just a matter of time

Look at how big it is, the hair is so thin, it burns out in a second.

Summary. Real copper wire burns more slowly, without open flame, and has less smoke or no smoke, while fake copper wire burns quickly with fire and has open flames and smoke. In addition, you can also look at the copper core, look at the wire core, look at the logo, and see.

The copper wire combustion method can qualitatively determine the presence of halogens in organic matter. A pure copper wire is heated until it is red-hot, dipped in a specimen and placed on a flame to burn, if halogens are present, the flame is green.

How to burn copper wires.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately

The load connected to the wire is too large, exceeding the rated current of the current, for example, the safe current carrying capacity of the copper wire is 10A, but it exceeds 10A during use, it becomes unsafe, then according to the mathematical expression of Joule's law: Q=I 2r*t (applicable to all circuits), the larger the current, the greater the heat, and the heat makes the wire burn out, the greater the current exceeding the safe current carrying capacity, the faster the burn-out.

Some wires are a collection of multiple thin wires, and some wires are broken due to the back and forth movement or other reasons, so the wires are constantly ignited in the process of energizing, and the resistance of the wires in this part of the virtual connection will increase, which will produce more heat, and the continuous accumulation of these heats will eventually fuse the wires.

The constituent wire and cable are composed of four parts: conductor, insulating layer, shielding layer and protective layer.

The conductor conductor is the conductive part of the wire and cable, which is used to transmit electrical energy and is the main part of the wire and cable.

The insulation layer is an indispensable part of the wire and cable structure that electrically isolates the conductor from the earth and the conductors of different phases to ensure the transmission of electric energy.

Wires and cables with a shielding layer of 15kV and above generally have a conductor shield and an insulating shield.

The function of the protective layer is to protect the wire and cable from the invasion of external impurities and moisture, as well as to prevent external forces from directly damaging the power cable.

Daily electricity safety is what we need to pay special attention to, if there is a phenomenon of burning, it is easy to bring safety problems to users, so do a good job in the maintenance of wires. So how to deal with the power outage when the wire is burned, and what to do about the daily maintenance of the wire, do you understand? Now let's take a look.

1. How to deal with the power outage when the wire is burned.

If the wire is burned and the power is lost, in this case, it is necessary to contact professional maintenance personnel in time to replace the burned wire. Because the wires are concealed, the replacement is a very large amount of work, so it is necessary to find the location where the wires are burned and broken, and then carry out construction, so that the maintenance budget can be saved.

Second, what to do for daily maintenance of wires.

1. In daily life, the wire needs to be avoided in a damp, heated and corrosive environment, so as not to cause damage to the wire. If the wire is concealed, these problems can be well avoided, but if the wire is surface-mounted, special attention is required.

2. Make a plan for yourself, every once in a while, do an inspection of the indoor wires to see if there are quality problems, if so, they need to be repaired or replaced in time, so as to ensure the normal use of the dress.

3. The load that the wire can carry is something that needs to be considered clearly when designing the wire and line at the beginning to ensure that it can be used normally. Moreover, when using electrical appliances, it is necessary to ensure that the total power does not exceed the rated power to avoid accidents.

4. For your own electrical appliances and circuits, you need to test them regularly, and if you find a problem, you need to repair them in time. If you have purchased a second-hand house, you need to replace the entire circuit in the room to prevent the aging of the wires.

How to deal with the power failure of the wire burned, and what to do about the daily maintenance of the wire, I will introduce it here, do you understand? If the wire is burned and the power is cut off, it will affect the daily use, so it needs to be repaired in time to ensure that there will be no problems.

1. If this happens, it may be because the wire is too thin and there is no way to carry some current to the home, so it will often burn out, and it is recommended that you replace some thick wires. 2. Normal wire joints, if our wire diameter is thick enough, it will not cause the joints to heat up, and it will not let the wires burn frequently, so it is very necessary to replace the wires.
