Judge the pros and cons of the power cord from the appearance
1. See if it is a regular power cord manufacturer: The safety of the power cord is very important, so it must be produced by a regular power cord manufacturer
Manufactured according to standards, fake and inferior non-standard power cords are often "three-no products" manufactured by small workshops, but they also have ambiguous origins and other signs, such as made in China, made in a certain province or city in China, etc. This is actually It is equal to the unmarked place of origin. If there is no company name or the company is not found online, it is non-standard. It is easy to cause problems with such a line.
Second, look at the price: the power cord produced according to the standard must be more expensive than the inferior non-standard power cord, so the price is not low, and the production cost of fake and inferior wires is low. Therefore, when they sell, they often Selling at low prices under the guise of cheap and good quality is deceived.
3. Look at the copper core: the qualified copper core should be purple-red, shiny, and soft to the touch. The fake and inferior copper core wires are purple-black, yellowish or white, with many impurities, poor mechanical strength, poor toughness, and will break with a little force, and there are often broken wires in the wires. The insulation layer of fake wires seems to be very thick. In fact, most of them are made of recycled plastics, which are prone to ageing. The cut corners of the copper core are extremely thin, and they will generate heat or even fuse when energized to the rated power.
Fourth, look at the weight: the weight of the poor quality wire is insufficient, or the length is not enough, or the copper core of the wire has too much impurities. Because the copper core is thin and the length is insufficient, the weight is obviously lighter than the standard wire.
