If you plan to decorate your home, what kind of wire is best for decorating the circuit?

Cord is good. Square wires should be multi-core. The main thing is to choose the real thing. Soft wire, high difficulty in counterfeiting. It's best to find an electrician you know to identify.

6 square meters of national standard copper wire is enough, too coarse, too fine, and the current is easy to burn.

Ranqiu said, each house is a separate line, four square copper heart soft line, brand, the highest money is good.

Decoration wires are certainly not ordinary BV wires (PVC insulated wires), they should be wires with better performance, such as fire-resistant, flame retardant, longevity, low smoke and halogen-free, high dielectric strength, multi-layer insulation and other properties, as well as copper quality to be good, wire diameter to be standard (not only up to standard, the national standard is measured by resistance, if you use electrolytic copper and the wire diameter is standard, the square millimeter is the wire diameter millimeter, and the energizing capacity is 5%-10% stronger than the standard wire, I have measured the square millimeter wire to meet the standard resistance, The best wire resistors. China has now required the use of fire-resistant wires for the decoration of entertainment venues, at least flame-retardant wires. Around 2000, some domestic enterprises launched a special wire for decoration according to the structure of spacecraft wires, which is to wrap a thin layer of flame-retardant PVC insulation on the copper core, and then wrap a thin layer of special nylon as a protective layer, which plays a role in high temperature resistance of 210 degrees and increasing dielectric strength and improving the life of the wire.

The United States has been using this kind of wire as a building wire since the 90s, and the penetration rate has reached 90%, and the model is THHN. Some of the decoration wires of Chinese enterprises are called BVN, some are called BVNZ, and some are called FVN, "N" is the code name of nylon, and the meaning with "Z" is flame retardant (such as Jiangxi Zhongce's Cantong brand decoration wire). This decoration wire is more cost-effective, **15 20 yuan per 100 meters high, a house costs about 200 yuan more, in fact, it is similar to some brand-name BV wires.

The refractory wire is wrapped with a layer of inorganic insulating mica tape outside the copper core, and then wrapped with a layer of polyvinyl chloride, the advantage is that when the wire is burned by an open flame, the wire can be energized in a few minutes to an hour (in a stationary state), which is divided into several fire resistance grades, and the disadvantage is that the insulation is thicker. If you have more questions, you can click on ID to consult.

According to the cross-sectional area of copper wire, the wire can be divided into different types, but in the specific decoration process, how should we choose? Today we will take the kitchen as an example to explain the choice of wires.

There are many electrical appliances needed in the kitchen, so there are many small electrical appliances in the kitchen, and the square or square is enough for a small electrical appliance, but in actual life, multiple electrical appliances are generally turned on at the same time, and the square can not meet the demand, so I recommend that the kitchen line choose 4 square meters, because it is not only enough, but also to prepare for the high-power electrical appliances that may be used in the future.

Small appliances like rice cookers are pretty much the same, but you can connect 4 square wires to the main line and square wires to the branch wires, which can save both costs and electricity.

Some families will also put high-power appliances such as refrigerators in the kitchen, it needs independent branches, because it runs around the clock, if it shares a line with other appliances, the current at the moment of switching will become larger, and the refrigerator branch line will be affected, and this situation will reduce the life of the refrigerator in the long run.

Therefore, it is best to use a separate branch line for high-power appliances such as refrigerators.

Although there are not many lighting facilities in the kitchen, they also need to be separated separately, and they cannot be connected with the socket, and there will be a ground wire in the socket, and it will be very wasteful if the lighting is connected.

Some households have a lot of household appliances, and there are many high-power appliances. I recommend setting up a separate distribution box in the kitchen, so that even if there is a short circuit, the other wiring will not be affected.

Lighting wires in your home.

Lighting wires are squared. Generally, the power of the home lighting load is not too large, and there are almost 6-8 lamps in the dining room, living room, main and secondary bedrooms, balconies, kitchens, and bathrooms, which are controlled within 1500 watts, and the square national standard copper wire is enough.

Wire for water heater socket.

The water heater is relatively large in household appliances, it is recommended to use 4 square wires, 4 square copper core wires can allow a maximum load of 7000-8000 watts, and the limit value is 8000 watts. Therefore, even if the water heater or bath bomb is turned on at the same time, there will be no major problems, and even if it is overloaded, it will only trip.

Wires for air conditioning outlets.

The air conditioner is also a high-power electrical appliance at home, so the socket is also a 4 square wire, of course, you can also use 6 square wires, but the construction difficulty of doing so will increase, and the area occupied by the socket bottom box will also become larger, and the wiring will become a very troublesome thing.

Wires for ordinary outlets.

The ordinary socket at home can use square wires, and the general load is controlled within 2500 watts. However, if you often use high-power electrical appliances, it is still recommended that you choose a 4 square wire.

Wires for kitchen outlets.

It is recommended to use 4 square wires for kitchen sockets, on the one hand, because there are many appliances in the kitchen, and on the other hand, because of the high frequency of use. Some kitchens are a square line to the top, and then arrange the socket below, with a square wire to connect the fire, all the sockets are connected from the square line separately, therefore, this practice is no problem.

Wire brands are complex, and as long as they are brands, there is basically no problem. Delixi, Zhengtai, Hangzhou Zhongce, Shanghai Panda, Anhui Lvbao, etc., of course, you had better learn to see the size of the wire core, the national standard square wire, the single-core copper wire is, as long as you buy the national standard package to detect the wire, there is absolutely no problem. So, when you buy, ask the merchant if they can package the test!

Some people also say that environmental protection wires, flame retardant wires, fire-resistant and flame-retardant wires, etc., are all gimmicks, but the price is increased without increasing the amount; It's just ** mode. In fact, the houses developed by general brand real estate developers do not need to change the wires, and they are generally branded wires.

Home decoration should use BVV2 multiplied and BVV2 multiplied 4mm copper core wires as power and lighting cables. Under normal circumstances, BVV2 multiplied by 4mm is used as the main line, and BVV2 multiplied by a single electrical branch line and switch line. For one-way air conditioning lines, BVV2 by 4mm or more can be used.

Now people's living standards have improved, every household has a variety of household appliances, decoration wire specifications are more important.

The wire must be indispensable in a family, its layout must be paid attention to, and the layout of its wire must be kept in a copy, or it will be difficult to repair it when the time comes. The copper core can be said to be the best of the wires, and you must distinguish what the circuit is used for when arranging it, so that you can lay out more wires. Copper core single strand.

Lighting squared, ordinary socket squared. Air conditioning. Kitchen.

Water heaters and other large power use 4 square special lines. There shall not be any joints, live wires, neutral wires, ground wires in the middle. Three threads are combined.

The switch is a live wire. Zero line. Control line.

Three are combined. The leased line must be a combination of three lines. In fact, the arrangement of wires must be professional, or not to waste materials, and the layout is not good, so it is very important to find professional personnel to install.

We generally use Hengfei and Jinbei for decoration here, I personally think that the quality of these two is good, and the home decoration is to use these two models, and the origin is specially checked to check that they are all made in Hengyang.

Of course, the wires used for home decoration should be a little more wire, preferably copper core wires, so as to ensure that there are no safety problems in use.

BVV is the national standard code, which is the copper sheathed wire BVV2* and BVV2*4mm, which represent 2 cores of square millimeters and 2 cores of 4 square millimeters respectively. In general, BVV2*4mm is used as the main line and trunk line, and BVV2* is used as a single electrical branch line and switch line. It is recommended to use BVV2*4mm or above wires for one-way air conditioning lines, and special ground wires are also available.

For the sake of fire prevention, maintenance and safety, the best home improvement wire specifications with the Great Wall logo of the "national standard" copper core wire, the wire slot area is generally: home improvement wire specifications lighting wire is selected in square millimeters, and socket wire is selected in square millimeters, pay attention to the air conditioning wire shall not be less than square millimeters, home negative wire (zero line ground wire) is best to use green and yellow two-color wire, and the switch wire (live wire) is used red, white, black, purple and so on. In the same home improvement project, the color and purpose of the thread should be consistent.

Wire is an indispensable basic building material in home decoration, and the quality of wire is directly related to the circuit safety of home decoration, so we must carefully purchase wire. So do you all know what kind of wire is best for home decoration? Do you know how to buy home improvement wires?

If you don't know, today I read this article on the installation of a network, you will be clear, let's learn together! Hope it helps!

Learn about wires.

Wire products used to transmit (magnetic) energy, information, and realize electromagnetic energy conversion. When home decoration, wires are indispensable building materials for concealed engineering decoration. To choose a suitable and high-quality wire product, you first need to understand some common sense about wire.

The difference between wire and cable.

The wires used for circuit decoration are usually referred to as wires and cables, and there are no strict boundaries between wires and cables. If there is a distinction between wires, it is that the wire is composed of one or several soft wires, covered with a soft sheath; A cable consists of one or several insulated wires wrapped around a tough outer layer made of metal or rubber. Cables are generally not needed in home decoration, and wires meet the requirements.

The regular size of household wires.

We often hear that the number of square wires refers to the size of the wire, and the common sizes are square, square, 4 square, 6 square, and 10 square. The wire square is a square millimeter, which refers to the cross-sectional area of the wire wire.

Household wire classification.

There are various types of wires, which can be divided into various types according to different uses. Compared with other wires such as engineering wires, household wires have relatively low functional requirements for wires. Specifically, household wires are classified as follows:

Hard wire: Professionally known as BV wire, mainly used for power supply, lighting, sockets, air conditioning, suitable for power devices, daily electrical appliances, instruments and telecommunications equipment with AC voltage below 450 750. The hard wire has a certain hardness, which will be more convenient in terms of folding and straightening.

1. How to buy wires.

Home improvement is inseparable from wires, especially in old houses, although wires are small, "responsibility" is great. What kind of wire is good for decoration? Pay attention to the precautions for the selection of decoration wires.

1.The cassette with the switch should be selected.

2.4 for lighting wires, socket wires, and air conditioning lines. Panda's is recommended for wires. The wire of the bath bomb is used with a socket wire, and if there is a condition, it is best to use 4.

3.The quality of the threading pipe must be good, put it on the ground and step on it, at least it cannot be easily stepped on. The surface of the pipe wall should be smooth, and the wall thickness should reach the strength of the fingers that cannot be broken, and there should be a certificate of conformity.

It is also possible to use the special galvanized pipe of the national standard as the threading pipe. Nowadays, there are generally two kinds of PVC pipes: 6 points and 4 points. If conditions allow, use 6 points.

A 4-point pipe can only wear lighting wires, and a maximum of 3 wires can be threaded in a pipe. 6 pipes can be threaded wires, and a maximum of 3 wires can be threaded in one tube. In addition, joints should be used when pvc pipes are docked, and glue should be used to connect them firmly.

Moreover, the connection between the PVC pipe and the wire box must be covered with a special sleeve, and the PVC pipe and the wire box must not be directly docked.

Second, the specification of the wire.

Household power cords should be BVV2 and BVV2 type wires. BVV is the national standard code, which is the copper sheathed wire BVV2 and BVV2, which represent 2 cores square millimeters and 2 cores square millimeters respectively. In general, BVV2 is used as the main line and trunk line, and BVV2 is used as a single electrical branch line and switch line.

BVV2 4 for one-way air-conditioning line, with dedicated ground wire. To buy wire, first look at whether there is the "Great Wall Mark" and production license number of the China Electrical Products Certification Committee on the wire packaging plate, and then see whether the outer plastic skin of the wire is bright in color and fine in texture, and there should be no open flame when ignited with a lighter. Informal products use recycled plastic, which has a dull color, loose texture, and can ignite an open flame.

Secondly, look at the length and ratio. The length of each roll of BVV2 is 100 5 meters, and the market price is about 280 yuan. The length of the irregular product varies from 60 to 80 meters.

Some manufacturers make the insulating outer skin thicker, making it difficult for insiders to see the problem. You can roughly calculate the length by counting the number of turns of the wire and multiplying it by the radius of the entire reel. This kind of product** is between 100 and 130 yuan.

Secondly, you can ask the merchant to cut a broken head and look at the copper core material. BVV2 copper core diameter mm, you can use thousands.
