Shenzhen Liyouda terminal wire , cable manufacturer , cable manufacturer, electronic wire is an abbreviation for the internal connection of electrical equipment. The electricity supply is mainly weak current, and it has a different concept from the cable in the field of strong electricity. Electronic wires are divided into three series: UL standard, 3C standard, and VDE standard. The AWG unit is usually the UL standard, and the cross-section square unit is usually the 3C standard or the VDE standard. Or UL-based two specifications.
I. Whenever possible, select products that meet the requirements of the specification. Wires and cables are classified as nationally enforced safety certification products in China. All production companies must obtain the "CCC" symbol certified by the China Electrical Products Certification Committee. Marked with "CCC" certification symbol. Export products need to pay attention to the US UL regulations and the EU's environmental protection RoHS requirements. Second, in terms of functions and specifications, it is really not a simple matter to choose the right one for you in a messy and hundreds of electronic wires. However, it is not difficult from the actual combat experience. It can be summarized in two steps, the top of the list, learning from peers, learning peers' practices, and launching the product first. Second, keep optimizing your peers' practices to make your selection more suitable for your products regardless of cost, function and environmental requirements. Of course, you can also simplify the complexity and consult our customer service directly, he will be willing to provide his professional opinion for you to choose.
Third, the appearance of the product is smooth and round, and the color is uniform. Wire and cable companies whose products meet the requirements of national regulations, in order to improve the quality of products and ensure that the products meet the requirements of national regulations, they strictly control the purchase of original materials, production equipment, and production technology. Therefore, the appearance of the produced wire and cable products meets the requirements of the specification: smooth and round, and uniform color. The appearance of the defective products is rough and matte. Regarding rubber-insulated flexible cables, the appearance must be round, and the sheath, insulation, and conductor must be tight and difficult to peel off. The fake and defective products have a rough appearance, large ovality, and low sheath insulation strength, which can be torn off by hand.
Fourth, the conductor is shiny, and the DC resistance and the conductor structure dimensions conform to national requirements. Goods that meet the requirements of national standards for wire and cable products, whether they are aluminum data conductors or copper data conductors, are relatively bright and non-oily. Therefore, the DC resistance of the conductors fully meets national standards and is outstanding.
