What is the difference between car wires and household wires? Can car wires be used on home outlets?

The outer insulation layer of automobile wires is oil-resistant, while household wires are ordinary national standards. Car wires can be used on household outlets.

The requirements of automobile wires will be biased towards cold resistance and high temperature resistance. If the rubber compound is of inferior quality, there is no way to meet this requirement. The high-voltage wire of the automobile has a very high withstand voltage, generally above 15kv, so its cross-sectional area is very small (because the current is very small), about, the thickness of the insulation layer is much lower than the thickness of the line, mostly using rubber insulation, plus impregnated cotton woven bag.

It can be used for household sockets, pay attention to the diameter of the wire should not be too small.

The automobile circuit is a low-voltage power line, and the line voltage value required by him is low, and the bending resistance and wear resistance of the wire are high, because the cross-sectional area of the wire is larger than that of the wire through a large current, and the insulation withstand voltage value of the household wire is greater than 500V.

1.The material is not the same as the low-voltage wire for road vehicles, which is different from the ordinary household wire. Ordinary household wires are copper monostasis wires with a certain hardness.

Automobile wires are copper polystasis soft wires, some soft wires are as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulating pipes (PVC)...

2.The cross-sectional area is not the same The common specifications of the wires used in automobile wiring harnesses are nominal cross-sectional area0 square millimeters.

3.The voltage is not the same China's household electricity uses 220 volts of alternating current, and the voltage resistance standard of the insulating sheath of the wire is more than twice that of 220 volts.

The quality of the power cord for automobiles is definitely better than that for household use, and the high temperature resistance, friction resistance and corrosion resistance are better.

As long as the diameter of the core is enough to drive the power of the electrical appliances at home, there is no problem, and you can rest assured that it will be installed and used.

Difference Between Car Wire and Household Wire:

1. The material is different.

Automobile wires, also known as low-voltage wires for road vehicles, are different from ordinary household wires. Ordinary household wires are copper monostasis wires with a certain hardness.

Automobile wires are all copper poly soft wires, some soft wires are as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulating pipes (polyvinyl chloride), which are soft and not easy to break.

2. The cross-sectional area is not the same.

The common specifications of wires used in automotive wiring harnesses are nominal cross-sectional areaWires of 0 square millimeters, all with allowable load current values, are used for wires of different power electrical equipment. The cross-sectional area of household wires is generally fixed.

3. The voltage is not the same.

China's household electricity uses 220 volts of alternating current, and the voltage resistance standard of the insulating sheath of the wire is more than double that of 220 volts; The voltage used in automobiles is 24 volts direct current, and the withstand voltage requirements of the wire sheath are much lower.

It is best not to mix household wires with car wires.

No way! Generally, the wires at home are too thin, because you want to carry a battery, and the thinnest 25 square copper core wire is required. There are standards for using ordinary wires, and not even thick lines can be used.

1. The material is different, and the car wire is also known as the low-voltage wire for road vehicles, which is different from the ordinary household wire. The wire used by ordinary people is a copper monostamen wire with a certain hardness. The car wires are all copper polyrui soft wires, some soft wires are as thin as hair, and several pie or even dozens of soft copper wires are wrapped in plastic insulating pipes (polyvinyl chloride), which are soft and not easy to break.

2. The cross-sectional area is different, and the common specifications of the wires used in automobile wiring harnesses are nominal cross-sectional areaWires of 0 square millimeters have allowable load current values, and are equipped with dusty wires for different power electrical equipment. The cross-sectional area of household wires is generally fixed.

3. The voltage is not the same, and the voltage standard of the insulating sheath of the wire is more than double that of 220 volts. The electrical voltage of the car is 24 volts direct current, and the withstand voltage requirements of the wire sheath are much lower. It is best not to mix household wires with car wires.

The household wire is 220V AC and the car wire is 12V DC. The requirements for the wires used in the car are higher, because the voltage used in the car is 12V or 24V. Therefore, in the case of the same power, the current will be larger.

To be on the safe side, it's best not to mix car wires with household wires.

Strictly speaking, it is best to use the special line, because the production of wires is different according to different application materials and other parameters.

How to say it, you can also use it, but there are certain safety hazards, the two kinds of wire from the specifications of the current resistance load are not the same, strictly speaking, it is best to use the special line, after all, the production of wires is different according to different application materials and some other parameters.

The line can be used, that is, pay attention to the connection, prevent accidents such as fire, and put safety first.

Whether household wires and electric vehicle wires can be mixed.

1. Different models:

Civil wires are BV and BVR; Car wires with RV.

2. Different standards:

Civil wires are single-core (BV) or multi-strand (BVR), although they are multi-stranded, they are not as thin as RV's, and they are not soft; The car wire is softer, and the copper wire inside is very thin, like a hair.

The model is not the same, the standard is not the same, the car generally uses RV wire, the civilian is generally BV and BVR, the car wire is softer, the copper wire inside is very thin, and the hair is general, the civilian is generally single-core (BV) or multi-strand (BVR), although it is multi-stranded, but not as thin as RV, so it is not so soft.

There is no difference in essence. The requirements for automotive wires are higher, because the voltage used in automobiles is 12V or 24V, so the current will be larger with the same power. In addition, the color of the wire used in the car is more.

There is no special difference, mainly depending on the size of the current to choose the wire diameter, I hope it will help you.

Generally, the line is selected according to the resistance, and the starting current is generally affected by the starting resistance, and there is no fixed value. The general one is 100-200a. The greater the current, the greater the resistance, the current is too low may be not well sealed or the valve is not closed tightly, the difference between the wire is mainly in the insulation material and visual discrimination, the conductive material is not different, it is determined by the load The line is equally divided.

Hello, I am glad to answer for you that copper-plastic wire and tinned copper-plastic wire can be directly substituted, as long as the cross-sectional load does not lift the current to meet the requirements of the circuit, it can be used normally. The power cord used in household appliances generally has a cross-sectional area of 450V and 500V to meet the requirements of the household appliance for Zhiliang current carrying capacity (working current). The wires used in automobiles, labeled as low-voltage wires, are generally resistant to voltage above 60V--70V, and the cross-sectional area meets the requirements of current carrying capacity (working current).

Hello, if you want to buy the car with the wire, I suggest that you might as well buy the emergency starting power supply, the emergency starting power supply, it is relatively small and convenient, just like the size of the power bank, and then connect to the vehicle can be used, if you buy the wire, you also need another car or another battery to help you start the vehicle, then this emergency starting power supply, like a small person and a shop are good brands.

Pacific Automobile Network] is not self-contained, need to buy, family cars with wires recommended outer diameter of 10mm or more copper wire. If the car cable is too long, it is easy to lose power, resulting in the vehicle being unable to start, so it is generally recommended to use a 3-4 meter long wire.

The car wire is used to save the emergency, when the vehicle can not start, you can call the car around you to take the power to start, the method of taking the power is that the positive pole of your own vehicle battery is connected with the positive pole of other people's vehicle battery, the negative pole is connected with the negative pole, and then start your own vehicle, which is an emergency measure. The inferior wire is not made of enough materials, the length is not enough, the cross-sectional area of the copper core is small, rough in workmanship, and some wire clamps are made of iron clamps, the protection measures are not in place, and the service life is not long and easy to burn out.

How to choose a car with wires:

1. Weight: The measured weight of the wire over 100 yuan is kilograms; The wire less than 30 yuan is only one-third of the weight of more than 100 yuan. It can be seen that the materials for the wire less than 30 yuan are insufficient.

Of course, there are some differences in the length of the two lines, which are 3 meters long for more than 100 yuan and only 1 meter long for less than 30 yuan.

2. Thickness: There is a great difference in the diameter of the two different wires. The diameter of the wire is millimeters for those over $100, but millimeters for wires less than $30.

The difference in diameter is 50% higher, and the difference is even greater when converted to cross-sectional area. The larger the cross-sectional area, the greater the current that can be withheld. Some children's shoes may not be convinced, and the wire that exceeds 100 yuan must be thicker than the skin.

3. Workmanship details: From the perspective of the clip material, the wire of more than 100 yuan is made of copper, and the wire of less than 30 yuan is only iron. As we all know, copper is second only to silver in conductivity, so it needs to withstand hundreds of amperes of current instantaneously when you put on a wire, which cannot be done without a good material.

More importantly, from a safety point of view, the clips of the wires of more than 100 yuan are covered with full soft rubber to protect them, which greatly reduces the possibility of electric shock for users. However, the wire less than 30 yuan is only for the touch part is soft rubber protection.

Automobile battery wires generally need to use copper cores with a diameter of about centimeters.

If the car does not replace the battery for a long time, there will be many problems. Due to the long life of the battery, it is natural to need to replace it with a new one when it is used for a long time. In fact, there are two main types of lead-acid batteries that are most common on the market.

One requires regular maintenance, while the other essentially does not.

If the car battery needs maintenance, you can unplug the plastic plug to check the electrolyte, of course, if the electrolyte is not enough, it needs to be added. If everyone's battery doesn't need maintenance, the battery should last for three to four years, and it's best to get a new one.

Extended information: The use of car batteries is described as follows:

During the use of the battery, the antimony on the grid will contaminate the sponge-like pure lead on the negative plate, weakening the back electromotive force in the battery after full charge, causing excessive decomposition of water, and a large amount of oxygen and hydrogen escaping from the positive and negative plates respectively, so that the electrolyte is reduced. Therefore, after a period of use, sulfuric acid should be supplemented so that the electrolyte remains containing 22-28% dilute sulfuric acid.

In a low temperature environment, the capacitance of the battery is much lower than that at room temperature. After a certain number of years of use, it is easy for the battery to fail to start when parked overnight or for a long time.

The model is not the same, the standard is not the same, the car generally uses RV wire, the civilian is generally BV and BVR, the car wire is softer, the copper wire inside is very thin, and the hair is general, the civilian is generally single-core (BV) or multi-strand (BVR), although it is multi-stranded, but not as thin as RV, so it is not so soft.
