Guangdong Dongguan Wire Factoryreminds that when purchasing wires, you should buy them from regular shopping malls and identify the national electrician certification mark (Great Wall pattern) and the trademark, specifications, voltage, etc. printed on the wires.

The standard for wires of Guangdong Dongguan Wire Factory:

1. Wires with good weight and quality are generally within the specified weight range.

2. Copper core wires with qualified copper quality should have a purple red color, luster, and soft touch. However, fake and inferior copper core wires have purple black, yellowish or white cores, high impurities, poor mechanical strength, poor toughness, and can break with a little force. Moreover, there are often broken wires inside the wires. When checking, you just need to peel off one end of the wire by 2cm, and then rub a piece of white paper slightly on the copper core. If there is black substance on the white paper, it indicates that there are more impurities in the copper core. In addition, the insulation layer of fake and inferior wires may seem thick, but in reality, most of them are made of recycled plastic. Over time, the insulation layer will age and leak electricity. 　　

3. Counterfeit and inferior wires from manufacturers are often "three no products", but they also have ambiguous origin labels, such as "Made in China", "Made in a certain province or city in China", which is actually equivalent to unmarked origin. 　　

4. Due to the low production cost of counterfeit and inferior wires, vendors often sell them at low prices under the guise of being cheap and high-quality, which can deceive people.
