How to tell if a power cord is real or fake?

ONE. How to determine the real power cord? You can take a wire head with a hand repeatedly bending, where the feel soft, good fatigue strength, plastic or rubber feel elastic and no cracks on the wire insulator is a superior product. Counterfeit power supply producers in order to obtain profiteering, regardless of the interests of consumers, mass production of poor-quality wire power products, disturbing the wire power market, harming the interests of the majority of users. Therefore, the correct choice of wire power supply appears to be very important, what kind of product is in line with the standard? Meet the standard requirements of the wire power supply enterprises, in order to improve product quality, to ensure that the product meets the standard requirements, in the purchase of raw materials, production equipment, production processes and other aspects will be strictly controlled. Therefore, the appearance of wire power supply products produced by a good wire power supply brand are in line with the standard requirements: smooth and round, uniform color. The appearance of counterfeit and poor-quality products is rough and lusterless. For rubber-insulated soft power, the appearance of the requirements of rounded, sheath, insulation, conductor close not easy to peel. But the appearance of counterfeit and inferior products is rough and oval, the sheath insulation strength is low, and it can be torn off by hand. Fourth, the conductor has a glossy, DC resistance, conductor structure and size in line with the standard requirements. Meet the standard requirements of the wire power supply products, whether it is aluminum material conductor, or copper material conductor is relatively bright, no oil, and thus the DC resistance of the conductor is fully in line with the standard, with good electrical conductivity, high security. Fifth, the length is accurate. Length is the difference between the standard requirements and the main intuitive method of counterfeiting inferior products. Conformity with the standard requirements of the length of the wire power supply products in line with the standard 100 ± 0.5m (i.e., 100 meters as a standard, allowing an error of 0.5 meters), to protect the interests of consumers.
