3C certified wire manufacturers talk about 3C certification standards for safe wire selection

Power supply is a highly dangerous product that may be caused by various reasons, such as leakage, damage or unsupported power supply. When purchasing power supply materials, you must pay attention to the certification of various power supply safety standards and quality standards to prevent purchasing products with safety hazards. product.

When choosing a power supply, many buyers tend to only focus on its price, power, and appearance. However, many people often overlook one thing, which is the national mandatory CCC certification, also known as 3C certification, which is basic to the safety of power supply wires. Certification.

3C certified wire manufacturer: National 3C certification mark

Although 3C certification is not a symbol of high performance, but a safety certification, the quality of products without 3C certification is definitely not up to standard. The 3C certification mark is usually affixed to the surface of the product or molded on the product. There is a random code behind the mark. Consumers can check this code through the National Quality Certification Center. The national standard’s requirement for power supply conductors is that for equipment with a rated current within 10A, if the length of the external power supply conductor is less than 2m, a soft cord with a cross-sectional area of at least 0.75mm2 should be used.

In addition to the national 3C certification, power products on the market also have American UL certification, 20 working groups, 22 working groups, etc. The power cord is marked with AWG American wire gauge, which is the standard for distinguishing wire diameters. This standard uses numerical values. means that the value represents the number of holes that the wire needs to pass through before forming a diameter. The larger the value, the more holes the wire passes through and the smaller the diameter of the wire. In other words, the number is inversely proportional to the diameter of the wire. Generally, it is used for PC power supplies. The wires are basically in three specifications: 20AWG, 18AWG, and 16AWG.

The cross-sectional area of the power cord cannot meet the minimum value required by the standard. If the cross-sectional area is too small, the power cord will be in a state where the operating current exceeds its capacity for a long time when using the computer power supply, and excessive heat will be generated after long-term overload work. , resulting in hot melt damage to the insulation layer of the power cord, exposing the conductive part of the power cord, causing leakage and even the risk of fire. Most of these power cords that do not meet the standard requirements are non-national standard certified power cords, that is, the cross-sectional area of the conductor , the color and material of the insulating sheath generally do not meet the requirements of relevant national standards, so this kind of power cord has serious safety hazards in use.
