What is the power cord and how to select it

Power cord - A power cord is a wire that transmits current. Generally, the mode of current transmission is point-to-point transmission. Power lines can be divided into AC AC power lines according to their purposes and click here to add pictures to explain DC DC power lines. Generally, AC power lines are wires with high voltage AC power. Such wires can be formally produced only after they have obtained safety certification according to unified standards due to high voltage. The DC line basically passes through DC with low voltage, so the safety requirements are not as strict as AC line. However, for safety reasons, countries still require unified safety certification.
How to select the power cable first
1. Standard issues
First of all, you need to know which country your products are sold to, and different customers have different requirements on the standard of power cord. For example, if you go to Europe, the products need to have the VDE certification of the European Union. If you go to the United States, you need the UL certification of the United States. If you go to Australia, Japan, Italy and other countries, there are relevant product certification requirements. The plugs you need are also different. If you cannot determine this, you may not be able to use the products you make, so this is the first problem.
2. Specification and thickness of power cord
The power cord is divided into two cores and three cores, which are different according to different types of electrical appliances. There are also specifications, such as 52 lines (light PVC sheathed flexible cable) and 53 lines (ordinary PVC sheathed flexible cable) in the national standard, and H03VV-F and H05VV-F in the VDE. In addition, the power line is also divided into thickness, such as 0.5mm2 0.75mm2 1.0mm2 1.5mm2. The specification and wire thickness mainly depend on the power of the electrical appliance. For details, please refer to the relevant national standards.
3. Color of power cord
This is mainly determined by the color of the product. If your product is white, it should be equipped with a white power cord and a black power cord. It is always not very beautiful.
4. Length of power cord
The length of the power cord is determined according to the user's use. If it is too long or too short, it is inconvenient for the user to use it.
