Why didn't the high flexibility cable break or break soon?
When using a highly flexible cable, did you experience a broken core? What is the reason for the broken cable? When we encounter this situation, how can we solve it? Shanghai Wire and Cable Xiaobian provides you with several suggestions. The cable chains can withstand long-time bending motion, extremely excellent tensile properties, flexibility of the conductor material of the flexible data cable, resistance to tensile aging of the insulating material, and core wire Combinations, collocation of auxiliary materials, protection of windings or inner sheaths, requirements for shielding and materials and requirements for outer sheaths.
At present, problems such as the breakage of the flexible data cable, the instability of the cracking and running signals, and crosstalk are caused by the following reasons:
1, the shielding layer of copper wire into the core
Causes: a. The improper handling of copper wire joints during weaving or winding; b. The cable's anti-twisting property is poor, and the braiding layer breaks by itself; c. The hardness of the insulating material is poor;
2, crust cracking
Reason: Poor material selection and lack of process, poor oil resistance and weather resistance. As for the hot conductors, insulation breakdown, poor anti-jamming effect, etc., it is not a technical problem but a problem of practitioners' morality; in fact, the design and manufacture of flexible data cables is not just to imitate imports (imports are also unreasonable Designing) and looking at these primary cognitive aspects of sample manufacturing, it is even more important to understand the principles of flexible data and the practical application environment so that the quality of the cable can at least have a good start.
3, the selection of raw materials. The outer sheath made of different modified materials has different functions, anti-UV function, anti-low temperature function, oil resistance and cost optimization. However, all of these outer sheaths have one thing in common, are highly wear-resistant and do not adhere to anything. The outer sheath must be highly flexible but also have support functions, which of course should be high pressure.
The above five points are for reference only and I hope to be helpful to everyone.
4, the conductor is broken, the cable should choose the most flexible conductor, generally speaking, the thinner the conductor, the better the flexibility of the cable, but the conductor is too thin, it will produce cable winding phenomenon. A series of long-term experiments provide a superb diameter, length and node-wise shielding combination of a single wire, which has excellent tensile strength.
Reasons: Poor quality, improper stranding, and unregulated conductor core assembly;
The above four points are for reference only and we hope to help everyone.
