What wire should be used for home decoration? The wires at home must be the safest. Then the choice of wires during decoration is related to the safety of electricity use in the future. If the quality of the wire is not good, it will lay a safety hazard for our future life. What wire should be used for home decoration?

What wire is used for home improvement? 1 1, household wire.

If it is for the decoration construction of buildings, there is no need to consider the wiring situation of residents at all, because after the completion of the main structure of all buildings, all power lines will be directly connected to every household, and it is not allowed to change the main line at will. But if it is a house built at home, the owner can use two specifications when wiring, one is copper wire and the other is aluminum wire. Optional16m2 for aluminum wire and16m2 for copper wire.

2. Socket wire

Ordinary sockets almost all appear at a position 30cm above the foundation ground, and are generally used by ordinary household appliances at home, and the load of these small household appliances is not particularly heavy, so ordinary wires will do. The common lines used in decoration construction are all 4-square copper wires. If you are decorating your home, you can choose aluminum wires, but when using wires for ordinary sockets, the specifications of aluminum wires must be above 16 square meters.

3. Special socket

The so-called special socket refers to some high-load household appliances in the family, such as air conditioners, refrigerators, water heaters and so on. Because these electrical appliances consume a lot of electricity and have high load, the requirements for the lines are also relatively high. It is acceptable to use 4-square copper wire, but the risk factor is also high. Therefore, in the process of decoration, the masters often replace the wires in the special sockets with copper wires of 10 square meters and aluminum wires of 16 square meters, which are consistent with household wires.

4. Lighting wires

If it is a lighting line, use the most common line. According to the power cord used by rural people, almost all of them are 1, 5 square meters of aluminum wire, but in fact this load is not up to standard. So in many buildings, the specifications will be improved. Use 1. 5 square copper wire or 2. 5 square aluminum wire.

What wire is used for home improvement? 2 What wires are used for home improvement?

1. It is best to use bvv2 * 2,5 and BVV2* 1, 5 for household power cords. Because BVV is a national code, it is copper sheath line BVV2 * 2,5 and BVV2* 1, 5, which respectively represent 2-core 2,5 mm2 and 2-core 1, 5 mm2. Generally, BVV2*2 and 5 are used as main lines and trunk lines, and BVV2* 1 and 5 are used as single branch lines and switch lines.

2. The specifications of home improvement wires are 1 and 5mm2, and the socket wires are 2 and 5mm2. Note that the air conditioning line should not be less than 2 and 5 square millimeters. At home, the negative wire (neutral wire/ground wire) is green and yellow, and the switch wire (live wire) is red, white, black and purple. We should keep the same colors and use lines in the same home improvement project.

How to choose home improvement wires?

1, length, which is one of the common tricks to cut corners. Some people will say that the wire I bought has a meter mark on it, but it is actually 100 meter. You should pay attention. He has the meter mark, but in the middle part, some profiteers are missing 10 meter. For example, mark 40 meters after 30 meters.

2, line diameter, this is one of the most common ways to cut corners on the market. For example, a 2-5 square foot BV wire commonly called a copper sheet is a single copper wire, because the cross-sectional area of the copper wire of this wire is 2-5 square millimeters. The diameter of copper wire of BV line of 2 or 5 square meters is 1 and 78 mm. ..

3, the quality of copper, real copper, is red, while brass is yellow. In addition, copper is soft and brass is hard. As long as you don't buy copper-clad aluminum (aluminum material, but coated with copper, usually used for soft wires), brass is not too fake at present.

4, PVC material, this is too professional, not much to say, what is certain is that no one makes copper wire very standard, but cuts corners on PVC. Because a ton of PVC is only 8000 yuan. And a ton of copper costs 50 thousand to 90 thousand yuan. So I can cut corners on many copper materials.

5.CCC certification mark. Wires must have CCC certification mark. Wire and cable products are national compulsory safety certification products. All production enterprises must obtain CCC certification and CCC certification mark, and have CCC certification mark on xx or products.

6. If the product conforms to xx and the wire product conforms to xx, the "CCC" certification mark, trademark, model specification, rated voltage, length, inspection, date, implementation standard, factory name, address and telephone number will be printed clearly, and they are all consistent with the product. These will be products produced by regular manufacturers, so you should see them clearly when you buy them.

What line is used for home improvement 3 At present, there are two kinds of lines commonly used in interior decoration, BV (hard line) and BVR (soft line).

BV (hard wire) refers to a single-core wire with only one copper wire, which is relatively hard. The advantages are long service life, difficult oxidation and short-circuit current impact resistance; The disadvantage is that the conductor is hard and cannot be bent and straightened repeatedly. Mostly used for burying walls, underground and trunk lines.

BVR (flexible cord) refers to a single-core wire with multiple strands of copper wires twisted together, which is relatively soft. Its advantages are safety, and it is more convenient to drag and move. Disadvantages are short service life and fast oxidation speed, especially after severe oxidation caused by short-circuit current impact and high temperature, core breakage and local heating are easy to occur, which need to be replaced in time.

In home decoration, BV line is much more used than BVR line.

Besides the types of wires, we also need to pay attention to specifications. The specifications of conventional household wires are 1, 5 square, 2, 5 square, 4 square and 6 square.

Household lamps, switches, ground wires, etc. , using 1, 5 square meters; Socket, Yuba cable, etc. , choose 2 or 5 square meters; The main circuit, special air-conditioning line and electric water heater are 4 square meters; 6 square meters is used in the trunk line, and it is rarely used in home improvement.

In addition, when buying wires, you must distinguish whether there is 3C certification on the package, and at the same time, the wires should be printed with information such as trademarks, specifications and voltages. You can also weigh yourself. Take the commonly used 100m2 and 5m2 copper core wires as examples. According to the formula, m (mass) = ρ (density) v (volume) = ρ * sh = 8,9 (g/cm3) * 0,025 cm2 *10000 cm = touch by hand when buying. If it is obviously lighter, it is likely to be tricky, so we should always pay attention.
