Can a wire that hasn t been opened for 20 years still work?

It is recommended to replace, and the replacement period of the normal condition of the general household wire is 10 20 years. Wire aging is easy to short circuit After the wire is aged, the insulation performance decreases, and it is easy to produce short circuits, especially in humid weather, short circuits occur when moisture is immersed in metal conductors, if the aging wires pass through carpets and combustible decorative materials, once a short circuit occurs, it is easy to cause fire accidents. Everyone must be vigilant.

The wire is mainly insulated by the outer layer of the skin, and after a long time, the insulation performance gradually decreases, and slowly ages and hardens, brittle or falls off, and then it does not have an insulation effect, and is easy to produce a short circuit. Especially in wet weather, although the appearance of the wire is intact, the insulation performance has been reduced, and when moisture soaks into the metal conductor, a short circuit will occur, and a fire will occur due to leakage. How to slow down or even prevent the external factors of wire aging, first of all, we need to understand the causes of wire aging, and find solutions for the causes.

Insulation moisture often occurs at the wire joint, in the humid climate, if the wire joint is not qualified, it will be easy to enter the water or mixed with water vapor.

Over time, it is easy to reduce the dielectric strength of the wire, resulting in aging failure. Chemical corrosion The wire has been used for a long time, and the outer layer has been subjected to chemical corrosion or electrolytic corrosion for a long time, resulting in the reduction of wire insulation performance.

Check that the wire insulation skin can be used if there is no aging, cracking, hardening and brittleness!

The wires are all pure copper, and good quality can be used again.

Summary. Hello dear, I'm glad to answer for you, can the wire that hasn't been opened for 20 years still work? Answer: The new wire can only be kept for 50 years at a constant temperature without unpacking, without pollution, although the wire is useless, but if the wire has been out of the factory for too long, resulting in the insulation layer of the wire has been aging, then the wire can not be used.

The old house is twenty years old, and the wires have to be replaced.

It is recommended to replace the wire in 20 years, because the age is relatively long, the wire will age, the insulation performance will decline, and it is easy to cause a short circuit, especially in wet weather, the moisture will soak into the metal conductor and cause a short circuit, so in order to ensure safety, try to replace the wire with a new one.

Hydropower projects are related to whether the living is convenient and comfortable, and also related to potential safety hazards.

Some old house wires after decades or even longer, water pipes and wires are aging, if you continue to use then it is not the best to say that there will be problems, and then it will be rebuilt when you move in later, which will be more costly.

Therefore, it is best to replace these aging wires and water pipes for the decoration of old houses. In fact, it is not just the old house, if the new house is not very good if the wire reserved by the developer is not very good, then it is also recommended to replace it, but it depends on the specific situation.

The decoration of the old house is not only the water pipes and wires to be replaced, including the old electrical box is also best replaced, because there will be some faults in the empty opening time of these electric boxes for a long time, or some have no leakage protection at all, and there is a state of failure if there is a false alarm, for the safety of the home electrical appliances, because the failure of the false alarm will also cause a short circuit of the electrical appliances, and the serious electrical appliances will be burned out, so it is best to replace the electric boxes empty.

The old house is twenty years old, and the wires have to be replaced. Because of the long term, the wire will age, easy to cause short circuit, insulation performance decline, especially in wet weather, moisture will soak into the metal conductor, short circuit, so in order to ensure safety, try to replace the wire with a new one.

If there is a plan to decorate, the wires are best replaced together, and the lines will have a certain degree of aging in 20 years, and there may be certain risks in daily electricity. However, it still depends on the specific situation, if the decoration is better with materials, it is not necessary to change it if there is no problem after checking, it is best to combine the situation of the house.

Precautions for decorating pulling wires

1. Scientifically select the thickness of the wire.

If the electrical power is large, you can choose a thicker wire, and the wire that is too thin is easy to heat.

It was even punctured, causing a fire.

2. Choose a reasonable installation form.

Depending on the situation, choose the light and dark installation method, which can be along the wall or ceiling.

The surface is laid, but the spacing between the wires should be appropriate, and it is forbidden to squeeze or fold, and if it is concealed, the wires are buried in the wall, which is generally operated by professionals.

3. The correct way to connect.

When laying wires, try not to produce too many joints, if there are too many joints, it will affect the appearance, and will also produce a large resistance, which is easy to cause the wire to heat and burn, if you want to connect, you must wrap it with special tape.

4. Use the ground wire correctly.

When decorating the cable, it is necessary to pay attention to some high-power electrical appliances, such as water heaters, air conditioners, etc., which must choose three-phase plugs and connect to the ground wire. The lighting wiring must not be connected one line at a time.

Summary. Dear, the wire can still be used after 20 years.

Dear, the wire can still be used after 20 years.

Can the wire still work after eight years of use?

Dear, the wire can still be used after eight years.

The life of the wire mainly depends on its materials, installation methods, load conditions, environment and other factors. Generally, the wires installed with conduit rounds are still in good performance after more than 20 years of use, and they can continue to be used and not used after a few years.

20 years of wire is recommended to be replaced, because the age is relatively long, the wire will age, easy to cause short circuit, insulation performance decline, especially if the air encounters wet weather, the moisture will be slag blind immersion into the metal conductor, short circuit, so in order to ensure safety, try to replace the wire with a new one.

Nowadays, when every family is decorating, they will pay special attention to the choice of wires, after all, it involves the quality and safety of electricity in the future life. Some old houses have been used for a long time, and it is a big expense to renovate the wires. Let's take you to understand, the old house has been 20 years old, the wires have to be replaced, and the household wires are 6 square or 4 squares?

The old house for 20 years the wire needs to be replaced, because the line base is aging, and now the electricity demand is not the same, the kitchen 4 square copper wire, the room square copper wire, there is no need to change, it is best to redesign the construction, one is because the wire will be aged for a long time, the second is that the original line design is not as large as the current load, the wire diameter is small, for the sake of safety it is recommended to replace all.

Household wires 6 square or 4 square is better.

1. The general lighting socket and lighting wire are enough to use square wires, and the lamps and lanterns at home are connected in series, generally not exceeding 500W, and the wattage of large crystal chandeliers will not exceed 1000W.

2. High-power electrical appliances at home, such as air conditioners and water heater sockets, can use 4 square wires. If you use 6 square wires, although it will indeed be safer, it will also increase the difficulty of construction, and the area occupied by the socket bottom box will also become larger, which is not conducive to home decoration.

3. There are many kitchen appliances, such as range hoods, rice cookers, microwave ovens, soybean milk machines, boiling kettles, etc. You can use a 4 square line to go to the top, and then arrange the socket underneath, use the square wire to connect the fire, all the sockets are connected from the 4 square wire macro or separately. However, it should be noted here that the 10A socket can only be connected to the square wire, and only the 16A socket can be connected to the 4 square wire.

The old house has been in the house for 20 years, and the wires of the household are 6 square or 4 square meters, and the whole content is introduced here. Wires, the larger the number of squares, the larger the volume, the more expensive, and the more complicated it is to install.
