For products such as power cords, I believe that we don’t need to say more, and everyone understands that the hydropower decoration in the daily decoration process can be said to be very important, especially the wiring decoration. Once the decoration is not good, it can be said that we are facing a very big danger because electric shock is a very dangerous thing, no matter if we encounter any news of electric shock, we will feel shocked in our hearts because It will be directly related to our life safety. Once there is a problem, it may be a fatal blow. Therefore, everyone must be extra cautious in the process of line decoration and don’t be careless. Take responsibility for your own safety. So how to choose the wire? Please keep these three points in mind!
1. Do not buy without safety specifications
Check whether the certificate of conformity is standardized, whether there is a quality system certification, factory name, factory address, inspection stamp, and production date; check whether the trademark, specification, voltage, etc. are printed on the wire. There must be a CCC certification mark on the wire, and some wires such as Jingde Special Plastic King have reached the CQC certification standard and a higher level of certification. Wire and cable products are national compulsory safety certification products. All manufacturers must obtain the "CCC" certification certified by the China Electrical Product Certification Committee, obtain the "CCC" certification mark, and have the "CCC" certification mark on the certificate or product. You must not buy such wires. Wires with specifications are not necessarily high-quality wires, but those without specifications must be inferior wires.
2. Do not buy wires that are made of poor materials
The insulation layer is too thick, and the wires that are too thick cannot be bought. The national standard clearly stipulates that the uniformity of the wire insulation layer should be thinner. The insulation layer of excellent wires has a uniform thickness, no eccentricity, and it is not easy to disconnect when pulled hard. We Check it out when you buy it. Disassemble the wire, the copper core is black, and the darkened wire cannot be bought. The excellent pure copper core is purple-gold in appearance, smooth and bright, without burrs, soft and durable, and not easy to crack.
Now, most of the wires use copper wire as the copper core. Copper is a very soft metal. When the surface is just cut, it is reddish orange with metallic luster, good ductility, high thermal conductivity, and electrical conductivity. 1. Electronic components are the most commonly used materials, but there are also some wires that use tinned copper wires as raw materials. For example, wires such as Jingde Special Plastic King use tinned copper wires. Copper wire coated with a thin layer of metallic tin on the surface of the copper wire. Tinned copper wire is relatively soft and has good electrical conductivity. Compared with bare copper wire, it has stronger corrosion resistance and oxidation resistance, which can greatly prolong the service life of weak current cables, but the price is also higher than copper wire.
In the past, aluminum wires were often used as wire cores, because they were cheap. With the improvement of people's living standards, people paid more attention to the quality and safety of wires, and aluminum wires gradually faded out of people's vision. Aluminum wires have poor strength and are easy to wire when wiring. Oxidation, temperature rise, and poor contact will occur after wiring.
The copper core of the wire is undoubtedly the copper wire with the highest cost performance and the tinned copper wire with the strongest performance. When purchasing wire and cable, you must look for the regular manufacturer, check the quality, and don’t buy some unqualified wires because of the cheap price. of wires.
3. Do not buy wires that are too cheap
Don't be greedy for cheap when buying wires. There are many brands of wires on the market. The quality of the wires must be guaranteed, so the price of the wires must not be too cheap. After all, you get what you pay for. The weight of the wire is very important. Generally, wires that do not meet the standards will be lighter. There will always be places that are short of weight.
When purchasing wires, you must pay attention to details, choose according to your own needs, and choose products produced by regular manufacturers. After all, the construction of the circuit is a hidden project, and everyone should pay attention to it when decorating, so as to avoid blind purchase and affect the decoration of the home.
