How to identify the quality of the cable factory's products? Cable quality and strength 1. Cables with high-grade brass in cable factories use high-purity oxygen-free copper, copper core color and luster, and poor copper wires are darker on the outside. 2. Phenolic plastic Phenolic uses high-quality phenolic phenolic, which has good bending performance and will never make lines when the wires are anchored and bent. Poor recycled plastics will have clear textures after bending several times, and they will break after repeated bending. 3. It is more difficult to be aware of the fact that the foot meter is in the limbs in the number of meters, because the customer is similar to the equipment that has not performed the step meter, and the abnormal use of the weight measurement method can see whether the cable is full meter.
Perhaps it is also a good way to let the factory spend time printing rice labels, but be careful, there has never been a way to print rice labels for lines with a diameter that cannot reach 5mm. 4. Copper is a precious metal. If there is more or less loss in the diameter of copper, a small amount of material and financial resources can be added. In this case, a soft ruler is required to measure the diameter of the copper wire. If there is never a hundredth, then the more complicated way is to take the whole coil of wire and turn it around to see if it can be hundreds of thousands lighter than the top-grade cable.
It may be possible to refer to the nominal gross weight paid by the factory. The nominal 1000-grain weight delivered by the Yaoluo factory is on the low side, so naturally, the quality of the product cannot be controlled. 5. Energy-saving agent In order to ensure the roundness of the ticketed cable, as for the multi-core cable, there will be fillers in the cores, and the thickness of the sheath should be made the same as the thickness. If the cable you get is not round, verify the filler. There is very little added, and the sheath is thin.
6. Wire bundles Multi-strand copper wires will stop wire bundles when they are used to improve the tensile strength, roundness, electrical performance and tightness of the insulating layer of the copper core, but only because the bundle wires will increase the use of copper Therefore, many factories have omitted this process. The way to detect fakes is to cut the core wire of the cable and check whether the copper wires on the outside are properly twisted together. Seven, braided cables containing copper mesh braid, the braid accounts for a large part of the material assets of the cable, and the coverage of the braid, twisting the angle to deter the electrical benefits of the wire, at the same time, the tight braid can accumulate the strength of the cable. Increase the electrical performance of the cable in a flexed shape. Therefore, it is important to see whether the braided layer has a high coverage rate and a uniform and fine weaving, which is an important factor for different cables such as 369.
