CUSTOMER CASE
The power cord is closely related to people's lives. If various quality problems occur in the power cord, it will cause various accidents, such as electric shock and fire. Therefore, be careful and careful when purchasing. Although consumers keep in mind the principle of being careful, how can they buy high-quality power cords?
The most intuitive thing is to check the quality certificate of the power cord. The manufacturers of the power cords have obtained this certificate after being inspected by relevant professional institutions. Therefore, consumers who cannot distinguish can directly ask the manufacturer to produce the relevant quality certificate. It becomes a basis for people to judge the quality of the power cord.
The second thing is to look at the cross section of the power cord. The most important thing about the power cord is the conductor inside. Generally conductors are made of copper wire, and the best copper wires have the unique luster of metal. If the copper wire does not have a bad luster, it means that the manufacturer has doped other metal elements in the pure copper wire, which has a great impact on its quality.
Consumers also look at the appearance of the power cord. The outer sheath is the most directly observed by people, because some manufacturers will not cut the power cord, so people cannot see the metallic luster. But the appearance is the most superficial, people can observe the quality of the appearance to distinguish the quality of the entire power cord. Generally, the material of the outer sheath must meet the high temperature resistance performance. People can use a lighter to ignite and check the high temperature resistance performance. If the performance is better, you can also trust its other functions.
After layer-by-layer inspection, people will finally choose the power cord that meets their wishes and make it of higher quality.
