Electronic connection line is an abbreviation for the internal wiring of electrical equipment. The energization is mainly based on weak current, which is different from the cable in the field of strong current. Electronic cables are divided into three series: UL standard, 3C standard, and VDE standard. The unit of AWG is usually UL standard, and the unit of cross-section square is usually 3C standard or VDE standard. Domestic electronic cable manufacturers are the first Mainly based on the two specifications of 3C or UL.

1. When selecting products, try to choose products that meet the requirements of the specification. In my country, wires and cables are classified as national mandatory safety certification products. All production companies must obtain the "CCC" symbol certified by the my country Electrotechnical Product Certification Committee and be on the product and certificate Marked with "CCC" certification symbol. Exported goods need to pay attention to the U.S. UL regulations and the EU's environmental RoHS requirements.

2. In terms of functions and specifications, it is really not a simple matter to choose the one that suits your request among the messy, messy, and hundreds of electronic cables. But from the actual combat experience, it is not difficult. It can be summarized in two steps. To the top of the list, learn from peers, learn from peers, and launch the product first. Second, continue to optimize the practices of peers to make your choice of products more suitable for you regardless of cost, function, and environmental requirements. Of course, you can also simplify the complexity and directly consult our Tang Hongsen customer service, he will be willing to provide his professional advice for you to choose.

3. The appearance of the product is smooth and round, and the color is even. Wire and cable companies whose products meet the requirements of the national standards strictly control the purchase of original materials, production equipment, and production processes in order to improve the quality of their products and ensure that the products meet the requirements of the national standards. Therefore, the appearance of the wires and cables produced meets the requirements of the specification: lubrication, roundness, and uniform color. The appearance of counterfeit goods is rough and dull. As for the rubber insulated flexible cable, it is required to have a round appearance, tight sheath, insulation, and conductor that are not easy to peel off. The counterfeit goods have rough appearance, large ovality, and low insulation strength of the sheath, which can be torn off by hand.

4. The conductor is shiny, and the DC resistance and the size of the conductor conform to the requirements of national regulations. The products of wire and cable that meet the requirements of the national standard, whether it is aluminum material conductor or copper material conductor, are bright and non-greasy. Therefore, the DC resistance of the conductor completely conforms to the national standard and is outstanding.
