How to recognize the quality of electronic cables?

　Electronic wire is a common name for the internal wiring of electrical equipment, electrification is mainly dominated by the weak power installation, with the weak power industry cable line has a different definition. Electronic wire has a distinction for the UL specification, 3C specification, VDE specification of the three series of products, the unit of AWG is usually UL specification, the unit of cross-section square meters is usually 3C specification or VDE specification, China's electronic wire manufacturers are mainly 3C or UL these two specifications for the leading. First, as far as possible in the selection of products that meet the requirements of the specification, cable and wire in China is categorized as mandatory safety verification of products, all manufacturers must be verified in China's Electric Welders Product Verification Association " CCC " representative, and in the products and certificates of conformity marked with the " CCC " verification of representatives. Export products need to pay great attention to the UK's UL specification and the EU countries of environmental protection RoHS requirements. Second, from the role of the specification. In the chaotic and complicated, hundreds of thousands of kinds of electronic wire in the selection of suitable for your requirements is indeed not an easy thing. But from practical experience will not be too difficult, can be summarized in two: 1, to learn from peers, learning from peers of the practice, can be the first product launch; 2, continue to enhance the practice of peers, so that your choice regardless of the cost, role and the natural environment requires more suitable for your products. Third, the electronic wire appearance of moisturizing glossy, uniform color. Electronic wire to meet the requirements of China's norms of cable and wire enterprises, in order to better develop the quality of products, to ensure that the products meet the requirements of China's norms, in the purchase of raw materials, production equipment, production processes and other levels of strict supervision. Therefore, the appearance of the cable and wire products produced to meet the specification requirements: moisturized glossy, uniform color. The appearance of the counterfeit remnants of the product is not smooth and dull. The requirements of flexible cables with eraser insulation layer: the appearance is glossy, and the wire sheath, insulation layer and conductor are strict and not easily detached. While the counterfeit remnants of the product appearance is not smooth, oval degree, sheath insulation layer strength is low, can be torn off by hand. Fourth, the conductor has gloss, resistance measurement, conductor structure limit, etc. to meet the specification requirements. Fulfill the specification requirements of the cable and wire products, both aluminum material conductor, or copper material conductor is relatively bright, no oil stains, and thus the conductor resistance measurement fully comply with China's norms, with excellent.
