How to distinguish between good and bad cables?
2020-07-08
1. It seems that the stores with the same cross section area all have card and non card wires. For example, if the wires with the same label are 2.5 square millimetre, the card label must be 2.5 m2, the non card label must be thin, and the price must be much lower. The non card markings are all products produced by small manufacturers, such as "three no" products or counterfeit and shoddy products, mainly for engineering or projects that seek cheap prices.
2. Copper core wires with qualified copper quality should be purple red, shiny, and soft to the touch. However, fake and inferior copper core wires have purple black, yellow or white copper cores, with many impurities, poor mechanical strength, and poor toughness. They can break easily with a little force, and there are often wire breaks inside the wires.
3. The price of the wire is not fixed based on the previous day's copper futures price, which means the price is very transparent. If you buy the wire again and the price quoted by the merchant is very low during the inquiry process, it is likely to be a fake or inferior product. Do not seek cheap prices.
4. Look at the fake and inferior wire cover. It is easy to break the wire cover when pulled hard, and the wire cover has no luster. There are more impurities to be removed and recycled.
5. Judging by qualifications, it is necessary to choose wires produced by legitimate brands, production qualifications, and cable manufacturers. Our company welcomes customers to inquire
