How should consumers choose high-quality wires?

In recent years, a series of fire incidents have been caused by aging wire lines. So how should consumers choose high-quality wires? I believe this is also the most concerned issue for consumers. Don't panic, the editor of PVC cable materials will give you a brief introduction. I hope it can help everyone's life!The first trick, purchase method:In big cities, it is actually very easy to buy genuine products. Just call the factory directly to buy it. In Beijing, call Kunlun Factory directly, and the 25-wire line is 168 yuan (the national standard wires of large factories are all full-length). In Shanghai, you can choose Panda, and there are also places to order online.For small cities, it is much more troublesome. Before buying, you can call the factory to ask if there is an agent in the city and whether there is delivery. If not, try not to choose these brands of wires, most of the ones bought outside are fake. When buying wires from unknown manufacturers, try to choose products from wire factories in big cities and buy them at agent points. They are cheap and reliable.The second trick is to test carefully:Generally, you will buy three kinds of wires, red, blue and flower wires for decoration. Cut off a section of each of the three wires and do the following tests1. Use a magnet to suck and see if the wire contains iron;2. Use a micrometer to see the diameter of the copper wire. 2.5 square is 1.78 mm, not less than 1.762. 4 square is 2.25 mm.3. Bring an electric meter to measure the resistivity.4. Look at the copper color. First, see if the colors of the three wires are consistent. The fake wires have a variety of colors and inconsistent thickness due to poor production technology; the real wires are consistent in thickness and color, especially bright metal color (because they are also alloys, and the color is a little different from pure copper).The third trick, observation indicators:1. First, check whether there is the "Great Wall Logo" and production license number of the China Electrical Product Certification Committee on the packaging label of the rolled wire;2. Then check 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 plastics, which are dull in color and loose in texture, and can ignite open flames.3. Secondly, look at the length and compare the price. The length of each roll of BVV2×2.5 is 100±5 meters, and the market price is about 280 yuan. The length of informal products varies from 60 to 80 meters. Some manufacturers make the insulation outer skin thick, making it difficult for insiders to see the problem. You can count the number of turns of the wire and then multiply it by the radius of the whole roll to roughly calculate the length. The price of this type of product is between 100 and 130 yuan.
