How can I know the quality of the harness cable?

First, look at the label. The content of the certificate of conformity of the wire produced by the regular manufacturers should include: 3C certification mark, certification number, model specifications, implementation standards, rated voltage, wire length, date of production, producer, inspector, factory name, address, fixed telephone number, anti-counterfeiting labeling and so on. Counterfeit products are often poorly printed labels or printed content is incomplete. Second, look at the surface. The plastic outer skin of regular wires is soft and smooth with uniform color. On its surface, it should also be printed with several contents on the certificate of conformity of the product, such as: 3C certification mark, certification number, model number, rated voltage, implementation standards, factory name and so on. At the same time, the handwriting must be clear, not easy to erase. Third, try bending. You can take a wire head with a hand repeatedly bending, where the feel soft, good fatigue strength, plastic or rubber feel elastic and no cracks on the wire insulation is superior. Shoddy wire insulation looks as if it is very thick, in fact, most of them are made of recycled plastic, as long as a little hard squeeze, squeeze the place will become white, bending 4 to 6 times the phenomenon of broken wires; four, tear insulation. High-quality insulation materials have a certain degree of mechanical strength and flexibility, easy to tear. And low-quality wires can be torn or pinched down by hand a piece; Fifth, look at the burning. According to the regulations of the wire insulation layer has a certain flame retardant. Peel off a section of insulation, with a lighter for ignition, after leaving the open flame can continue to spontaneous combustion is poor quality line. Sixth, check the thickness. Intercept a section of the insulation layer, look at the cross-section of the insulation layer is visible to the naked eye air holes, whether the core is located in the center of the insulation layer. Not centered because the process is not high and caused by the phenomenon of eccentricity, there are air holes in the use of insulation material is not qualified. Eccentricity of the most likely to leak in the thinner side, there are air holes also affects the compressive strength. Seven, look at the copper wire. The color of high-quality copper wire is bright red, and poor-quality copper core line is purple, black, yellow or white, hardness, impurities, poor mechanical strength, toughness is not good, a little force that will break, and the wire is often broken within the phenomenon. For multi-stranded soft wire, touch the top of the copper wire with your palm, the feeling should be flat, and no stinging sensation, feel softer. Otherwise, it is poor quality wire. Eight, look at the price. Due to the low production cost of counterfeit wire, therefore, vendors in the sale, often inexpensive and beautiful as a front for low-priced sales, so that people are fooled.-9、About BBC Electronic Products Network platform related to the introduction and sales of products briefly: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products}; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable products we can provide solutions, please contact the following Division Division I business personnel!
