How thick should the wire be in the car

1. In general, the wires of household cars are almost about 10 square meters, but it is necessary to use special car wires to charge the vehicle, so as to ensure the success rate of the power without damaging the battery.For large trucks, it needs about 25 square meters of wire.

2. Theoretically, the finest gasoline car should also use 6 squares, which can't be thinner than this. Because 6 square meters is very reluctant. In practice, it is recommended to use more than 10 square meters of copper wire. For diesel cars, they should be thicker. 6 squares and 10 squares represent the cross-sectional area of the copper core.

3. Purchase is not only related to thickness, but also to length. If the wire is too long, it is easy to lose power, causing the vehicle to be unable to start. It is generally recommended to choose a 3-4-meter-long wire. In addition, don't choose a wire worth tens of yuan. Its quality is very unreliable, which is not only easy to leak, but also may damage the car.

How much is the price of car wiring? The price of car wiring

is charged according to the distance. Professional companies will not charge indiscriminately, usually all of them are between 20 and 50 yuan. In fact, you can call the insurance you are in, and usually all of them are free of charge.

If you don't give this service, you need to pay for it yourself, usually about 200 yuan.

50 to 100 yuan per car. Any car purchase may have some embarrassing problems, the most common and embarrassing thing is that the car runs out of electricity and gasoline.When your car's battery runs out of power, the insurance car can call the insurance company for free door-to-door service, usually three times a year.

It costs 50 to 100 yuan to charge a car once. When the car battery loses power, it will affect the power supply system of the whole vehicle, making it difficult for the car to start. If the engine is turned off halfway and can't be started, the towing cost is higher. At this time, we can find other cars for electric emergency.

However, if it is for other reasons, the corresponding expenses will be deducted according to the specific situation, such as the cost of replacing the battery, the cost of leaving the car, etc. Of course, if you want to solve it by yourself, you can charge the battery by using a cable to connect with other cars.

According to the market price on May 25, 2021, the door-to-door battery of the car is charged according to the cityThe difference between the level and distance of the city is generally about 50 yuan to 200 yuan, and the cost of long-distance rescue is even higher. When the car battery loses power, it will affect the power supply system of the whole vehicle, making it difficult for the car to start.

How to choose a car to install wires?

The wiring method of the car is out of power: Before wiring, the specifications of the wire should be well adopted, such as within 2 meters, 16 square copper wire for small cars, 25 square copper wires for trucks, 35 square copper wires for heavy trucks, etc. Accurately and clearly determine the positive and negative poles of the battery, and turn off the electrical appliances before connecting. When connecting, the positive pole is to the positive pole, and the negative pole is to the negative pole, that is, the battery is connected in parallel.

You can use the 25-square wire of national standard pure copper. When the car is electric, you must use a special car line. If you want toIt is replaced by ordinary wires. Be sure to use a large square pure copper national standard wire, which will not affect the effect of electricity, and will not cause damage to the two cars at the same time.

Firstly, it depends on what materials it is, and secondly, it depends on the number of times it is used. Generally speaking, if you use it once or twice occasionally, there will be no problem. Precautions when installing wires. When using the clip, the hand should be held in the position of the insulated handle.

Use a 3-4-meter-long BVR line with an outer diameter of 10 mm or more. Continue to charge for about five minutes to achieve the purpose of emergency charging. Automobile non-electric wiring method: Before connecting, good wire specifications should be adopted, such as 16 square copper wire for cars, 25 square copper wire for trucks, and 35 square copper wire for heavy trucks within 2 meters.

With purchase notes: The purchase is not only related to the thickness, but also to the length.If the wire is too long, it is easy to lose power, causing the vehicle to be unable to start. It is generally recommended to choose a 3-4-meter-long wire. In addition, don't choose a wire worth tens of yuan. Its quality is very unreliable, which is not only easy to leak, but also may damage the car.

How big is the wire for a car?

General homeIt is almost about 10 square meters to use a car to set up wires, but it is necessary to use a special car to set up wires to power the vehicle, so as to ensure the success rate of power-up and not to damage the battery. For large trucks, it needs about 25 square meters of wire.

In actual operation, it is recommended to use copper wire of more than 10 square meters. For diesel cars, it should be thicker. 6 squares and 10 squares represent the cross-sectional area of the copper core. There are two ways to express the thickness of the line. One is to represent the cross-sectional area (mm) of the copper core of the wire. The other one is represented by the diameter of the copper core (mm).

Car fire wire generally uses 16 square meters, truck 25 square meters copper wire, and heavy trucks 35 square meters copper wire. Because the starting current of the engine is large, and the battery voltage is low and the current is greater, so the smaller the resistance of the fire wire, the better.When the battery of the car loses power, it is difficult for the car to start, and the loss of the battery will also affect the power supply system of the whole car.

You can use the 25-square wire of national standard pure copper. When the car is electric, you must use a special car ride line. If you want to replace it with ordinary wires, you must use a large square pure copper national standard wire, so as not to affect the effect of electricity and will not cause damage to the two cars.

In theory, the finest gasoline car also needs 6 square meters, and it can't be thinner than this. Because 6 square meters is very reluctant. In fact, it is recommended to use copper wire of more than 10 square meters. Diesel cars should be thicker. The cross-sectional area of the copper core is 6 square meters and 10 square meters.

Automotive wire standards and specifications

1. Check whether the size of the wire meets the relevant requirements and whether the model is correct.The incision must be neat, the wire must not be scratched, and the wire must not be dirty. Whether the grouping is neat. Check whether the trimming is neat and the size is correct. When trimming the grouping, the core line cannot be drawn.

2. The length of the trunk line and protective sleeve should not be less than 100mm, which is a multiple of 10. For example, 100mm, 110mm, 120mm, etc. 2 The length of the pipe should not be less than 30mm. The distance between the contact and the branch point should not be less than 20 mm.

3. Exceed the allowable temperature of the conductor. In order to ensure a certain mechanical strength, the cross-sectional area of low-pressure conductors is generally not less than 0.5mm2. The cross-sectional area of a single car wire is 0.0.825, etc. The recommended specifications of low-voltage conductors for automobile 12V electrical system are shown in the table.

4, 1 ordinary wire: Ordinary low-voltage wire is a copper multi-filament soft wire, which is divided into QvR type and QFR type according to the material of the outer skin insulation coating.

5. The specifications of the first three core wires are all 7X¢O.39mm, and the latter wire is a single ¢3mm graphite core wire. Models of low-voltage wires: polyvinyl chloride as the insulating layer and polyvinyl chloride-butyl rubber composite as the insulating layer. According to the purpose, low-voltage wires can be divided into general use and start-up use.

What wire is the most durable in a car

Generally, many modern automobile battery wires use aluminum harnesses, so aluminum harnesses are relatively soft. But it's better to use copper wire, but copper wire is expensive and hard.Many car companies do not use copper wire harnesses in order to cut corners, so my personal suggestion is to use a harder copper wire.

Car battery wire and fire wire generally need to use a copper core with a diameter of about 0.5 cm. If the car does not replace the battery for a long time, there will be many problems. Due to the long service life of the battery, it is natural to replace the new battery when it is used for a long time. In fact, the most common lead-acid batteries on the market are mainly divided into two types.

American standard: GTE GPT GXL SXL TWE TWP TXL, etc.

In the whole car audio system, in addition to the host, amplifier, speaker and soundproofing, there is one thing that is very important, that is, the wire connecting the entire car audio system, because a good wire can not only ensure the safety of the car line, but also reduce the attenuation of transmission, and the anti-interference ability is naturally stronger. It's.
