What wires should I use for home decoration? What brand should I use?

How to choose wires

Home improvement is inseparable from wires, especially old houses. Although the wire is small, it is "responsible". What line should be used for decoration? Matters needing attention in choosing decorative lines.

1. The cassette with switch should be of good quality.

2. Lighting line 1.5, socket line? 2.5? Yes, the air conditioning line uses 4? Yes Recommend panda line. Socket cable for Yuba's cable? 2.5? Yes, if conditions permit, 4 is the best.

3. The quality of threading pipe must be good, and it should be placed on the ground and stepped on by feet. At the very least, you can't be trampled easily. The threading pipe shall be flame-retardant PVC conduit, and its wall surface shall be smooth, and the wall thickness shall reach the strength that fingers can't squeeze, and there shall be a certificate of approval. It is also possible to use the national standard galvanized pipe as the threading pipe. Now PVC pipes are generally divided into 6 points and 4 points. Use 6 points if possible. Can I only wear 4 in charge? 1.5? Lighting wires, a lamp tube can only wear up to 3 wires. Can I wear a 6-gauge pipe? 2.5? Wires can only be threaded in one tube at most? 3? Root? 2.5? Wires. In addition, PVC pipes should be connected with connectors and firmly connected with glue. Moreover, the connection between PVC pipe and box must be covered with special sleeve, and PVC pipe and box must not be directly butted.

Second, the wire specifications

The household power cord shall be of BVV2×2.5 and BVV2× 1.5 models. BVV is the national code, which is sheath line BVV2×2.5 and BVV2× 1.5, representing 2 cores 2.5 mm2 and 2 cores 1.5 mm2 respectively. Generally, BVV2×2.5 is used as the main line and trunk line, and BVV2× 1.5 is used as the single branch line and switch line. BVV2×4 is used for one-way air conditioning special line, and special grounding wire is provided. When buying wires, we should first consider whether there is the "Great Wall logo" and the production license number on the winding packaging label, and then look at whether the plastic skin on the outer layer of wires is bright in color and delicate in texture, and there should be no open flame when lit with a lighter. Informal products use recycled plastics, which are dull in color and loose in texture, and can ignite open flames. Second, look at the length and price. BVV2×2.5 each roll length1005m, the market price is around 280 yuan. The length of informal products ranges from 60 meters to 80 meters. Some manufacturers make the insulation sheath very thick, so it is difficult for experts to see the problem. You can count the number of turns of the line and multiply it by the radius of the whole roll to roughly calculate the length. The price of such products ranges from 100 to 130 yuan. Secondly, you can ask the merchant to cut a broken head and look at the copper core material. BVV2×2.5 copper core diameter 1.784 mm, you can measure it with a micrometer. The regular product line is made of pure copper, and the outer layer is bright and slightly soft. Informal product copper is dark and hard, belonging to recycled copper, with high resistivity and poor conductivity, which will increase the temperature and be unsafe. Finally, when buying wires, you should go to professional stores such as power supply stations or factory salesrooms to buy them.

Home improvement is inseparable from wires, especially old houses. Although the wire is small, it is "responsible". Many fires are caused by aging wires, unreasonable configuration, or poor quality of used wires. Therefore, consumers must polish their eyes when buying wires, carefully identify them, and prevent problems before they happen. At present, there are many kinds and specifications of wires on the market, and the price is chaotic, so it is difficult for consumers to choose. As far as the prices of 2.5 square mm and 4 square mm copper core wires commonly used in home decoration are concerned, the price difference of a winding wire with the same specification can be 20% ~ 30% because of different manufacturers. As for quality and length, it is even more difficult for consumers to judge. According to insiders in the wire industry, the huge price difference of wires is caused by the different raw materials used in the production process. The main raw materials for producing wires are electrolytic copper, insulating materials and sheath materials. At present, the electrolytic copper in the raw material market is about 20 thousand yuan per ton, while the recovered copper is only about10.5 thousand yuan per ton; The price of high-quality products of insulating materials and sheathing materials ranges from 8000 yuan to 8500 yuan per ton? Yuan, and the price of defective products is only 4000 per ton? Yuan ~ 5000 yuan, the price difference is even greater. In addition, insufficient insulator length and rubber content are also important reasons for the price difference. The length of each coil of the first-class product is 100 meter, while the second-class product is only about 90 meters. Insulators with excellent rubber content account for 35% ~ 40%, and defective products only account for 15%. By comparison, it is not difficult for consumers to see that the difference in the sales price of finished wires is caused by difficult materials.

Third, how to distinguish the advantages and disadvantages of wires

What wire is used for decoration? Detailed rules for selection of wires for decoration: For fire prevention, maintenance and safety, it is best to choose "national standard" copper-core wires with the Great Wall logo. The load area of trunking is generally: lighting wire 1.5mm, socket wire 2.5mm, air conditioning wire not less than 2.5mm, negative wire (neutral wire/ground wire) and switch wire (live wire) with green and yellow double colors. However, in the same home improvement project, the color of the line should be consistent.

When buying wires, first look at whether there is a "Great Wall logo" and the production license number of China Electrical Product Certification Committee on the wire packaging;

Then look at whether the plastic skin on the outer layer of the wire is bright in color and delicate in texture. There should be no open flame when lit with a lighter. Informal products use recycled plastics, which are dull in color and loose in texture and can ignite open flames;

Secondly, from the perspective of length and price ratio, the length of each roll of regular products is100 (5) meters, and the length of informal products ranges from 60 to 80 meters. Some manufacturers make the E insulation sheath very thick, so it is difficult for experts to see the problem. Generally, the number of turns of the conductor can be counted, and then multiplied by the radius of the whole roll to roughly calculate the length.

The regular product wire is pure red copper, and the outer layer is slightly bright and soft. The informal product copper is black and hard, belonging to recycled miscellaneous copper, with high resistivity and poor conductivity, which will heat up and be unsafe.

Distinguish between good and bad.

1) depends. See if there is a quality system certificate; See if the certificate is standardized; See if there is a factory name, address, inspection stamp and production date; See if there are any trademarks, specifications, voltages, etc. Printed on the wire. It also depends on the cross section of the copper core of the wire. Superior copper is bright and soft, otherwise it is inferior.

2) try. It is advisable to bend the end of a wire repeatedly by hand, and those with soft hand feeling, good fatigue strength, high elasticity of plastic or rubber hand feeling and no crack on the conductor insulator are excellent products.
