What is a power cord? How to choose a power cord?

I. What is a power cord? A power cord is a wire that transmits electrical current. Usually the way of current transmission is point to point transmission. Power cords can be divided into AC power cords and DC power cords according to their purpose. Usually AC power cords are cords that pass through higher voltage alternating current, and this type of cords need to be standardized to obtain safety certification before they can be formally produced due to the higher voltage. The DC line is basically through the lower voltage direct current, so the safety requirements are not as strict as the AC line, but for safety reasons, countries are still required to unify the safety certification.

-II. How to choose the power cord? 1, the standard problem first need to understand the products you produce, is sold to which, different with the family, in the power cord standards have different requirements. Such as: to Europe, the product needs to have the European Union's VDE certification, to the United States, the need to have the United States of America's UL certification, to Australia, Japan, Italy, and many other related product certification requirements, the need to be equipped with the plug is not the same, if this can not be determined, made out of the product you may not be able to use, so this is the primary problem. 2, the specifications of the power cord and the thick line of the power cord is divided into two-core and three-core, according to different types of electrical appliances, the power cord is not the same, but the power cord is not the same as the power cord. Core, according to different types of electrical appliances are different. Also divided into specifications, such as the national standard of 52 lines (light PVC sheathed flexible cable) 53 lines (ordinary PVC sheathed flexible cable), VDE points H03VV-F, H05VV-F, etc. And, the power cord is also divided into thick and thin. And, the power cord is also divided into thick and thin, such as: 0.5mm2 0.75mm2 1.0mm2 1.5mm2, specifications and the thickness of the wire is mainly based on the power of the appliance is different, for details, please refer to the phase phase of the national standard. 3, the color of the power cord this is mainly based on the color of the product, if your product is white, you should be accompanied by a white power cord with a black power cord. 4, the length of the power cord length of the power cord is to be determined according to the user's use, too long or too short, the user in the process of use, is not convenient.
