Electricity is the main energy used in modern people's life and work, and the power cord is an important medium for the energy transmission. Safety and efficiency are the key points that people need to consider when choosing a power cord. Consumers can judge the quality of the product from the following aspects.
1. Certificate inspection. When purchasing a product, you first need to check the product's quality inspection certificate. Only the power cord that has passed the professional quality inspection and obtained the certificate is the most trustworthy, otherwise it is a substandard product.
2. Cross-section inspection. Most wires use copper wire or aluminum wire as the main conductive medium, and the authenticity of the product can be determined by distinguishing the quality of the medium. The black or white metal cross section indicates that the medium has been oxidized, which will greatly affect its conductive effect, and even pose safety risks. You should avoid buying such products. For a high-quality power cord, the surface of the medium should be bright, free of burrs, smooth and full of toughness.
3. Length check. According to the specific needs of use, it is necessary to choose a moderate length wire. It is necessary to know the length of the power cord in advance according to the specific furniture and decoration design, and only by knowing the knowledge can you find the right product quickly and effectively.
The above are the methods that consumers can use when purchasing power cords. I hope everyone can find satisfactory products in accordance with the above methods.
