What Is A Power Cord?

Power cord - A power cord is a wire that transmits current. Usually, the mode of current transmission is point-to-point transmission. According to the purpose, power lines can be divided into AC power lines and click here to add pictures to illustrate DC power lines. Generally, AC power lines are made of AC wire with high voltage. Such wire can only be formally produced after obtaining safety certification according to a unified standard because of its 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 cord first

1. Standard questions

First of all, you need to know which country your products are sold to. Different families have different requirements on the standard of power cord. For example, for countries going to Europe, the products need to have the VDE certification of the European Union; for countries going to the United States, they need to have the UL certification of the United States; for countries going to Australia, Japan, Italy and many other countries, there are relevant product certification requirements, and the required plugs are also different. If this is not determined, the products may not be usable, so this is the first issue.

2. Specification and thick wire of power cord

The power cord is divided into two cores and three cores, which are different according to different electrical appliances. There are also specifications, such as 52 wires (light PVC sheathed flexible cable) and 53 wires (ordinary PVC sheathed flexible cable) in the national standard, and H03VV-F and H05VV-F in 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 are mainly different according to the power of the electrical appliance. For details, please refer to the phase national standard.

3. Power cord color

This is mainly based on 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 beautiful.

4. Length of power cord

The length of the power cord should be determined according to the user's use. If it is too long or too short, it is inconvenient for the user to use it.
