Do you use the right wires for home decoration?
Firstly, the quality of wire insulation is good
The insulation skin is used for insulation and is also an important link in protecting copper wires from damage. How to judge the quality of wire insulation? We can cut out a section of insulation sleeve for stretching. If the insulation sleeve turns white or breaks, it is of poor quality. If there is no problem with multiple stretching, it is safe and reliable. Or burn it with fire. Fake wires can quickly burn with open flames and emit thick smoke when burned. True wires burn slowly, with little or no smoke, and no open flames.
Secondly, the weight and length of the wires must meet the standards
Generally speaking, the weight of a bundle (100 meters) of 2.5 square meters of wire that meets the standard should be within 3 kilograms, and even if there is an error, it should not exceed 0.2 kilograms. If the error of the purchased wires is too large, there may be shoddy workmanship or quality issues with the copper wires. Such wires must be returned; As for the length, although the country does not mandate that wires must be measured in meters, many manufacturers also measure in meters, with a typical wire length of 100 meters.
Thirdly, the quality of copper wire is better
The higher the brightness of the wire, the more uniform and glossy it is, without a sense of layering, indicating that the copper quality is better. Qualified copper wire cores should be purple red, shiny, and soft to the touch. Cut off a small piece of plastic outer skin, carefully examine the copper wire inside, and lightly touch the top of the copper wire with the palm of your hand. The feeling should be smooth and painless, with a relatively soft touch.
Fourthly, the wire has better fire protection function
Ordinary PVC wires are prone to aging, contain halogens, and are prone to combustion. And when burned, it will produce a large amount of thick smoke and toxic gases, which are harmful to human health. Therefore, for household electrical wires, it is best to choose fireproof wires with good fire resistance, long service life, and guaranteed safety. Chuangyuan Fireproof Wire, as a fire-proof wire that integrates functions such as fire prevention, power saving, and durability, has the world's first firewall patent, with high temperature resistance of 1000 ℃ and continuous power supply for 90 minutes. It is a reliable choice for household wires.
