Drag chain cable and high flexibility cable selection tips share

With the development of science and technology, the needs of the progress of The Times, in a variety of industrial equipment and power places will be applied to the tow chain cable, then how to buy high-quality tow chain cable? Below, Xiaobian to share:

The first is to judge good and bad by the frequency of movement. Under normal circumstances, buyers often judge the quality of the purchased product by the frequency of the cable, which frequency is more appropriate? According to experts, the frequency of movement is 8 million or 10 million times. For example, conventional cables generally exist in the tow chain box, and they will play the role of the tow chain in the movement of low frequency and large bending radius, in fact, different specifications of cables will have different models of parameters, as long as the range of these parameters allows, you can reach millions of times of high movement frequency. But to get there

To such a high frequency of use, there are certain conditions.

Second, judge the quality by its softness. In general, people usually think that the higher the flexibility of the cable, the better, because they think that the cable is easy to bend in the process of using the drag, if the softness is good, it is not afraid of damage, of course, the cable has a certain softness is very necessary, but can not simply judge the softer the better the cable, for example, the silicone cable can not be used as a drag chain cable. Because even though silicone rubber has good electrical properties and heat resistance, its mechanical properties are very poor, and it is not wear-resistant or tensile. Therefore, the core can not play a good protective role, easy to wear the core, serious

The core will break. Therefore, we can not blindly rely on the softness to judge the quality of the tow chain, but need to make reasonable structural design to meet the needs of different environments.

Third, according to whether the wire needs to move to determine whether it is necessary to order the tow chain cable, the general PVC sheath wire is not wear-resistant, not resistant to bending, long-term movement is easy to damage the sheath leading to the wire is not available, the sleeve of the tow chain cable uses improved PVC, specific wear resistance and bending characteristics;

Fourth, according to the frequency of wire movement to judge what type of cable to buy, in order to better meet the needs of different customers, the cable is divided into different grades, the moving speed is less than 30 times/minute recommended moderate drag chain 30-50 times/minute recommended height drag chain, more than 50 times/minute push PUR (polyurethane) material sheathing, This product is currently the best tow chain cable in China, the biggest feature is super wear-resistant, and the lighter is not open fire.

Fifth, after selecting the medium, height or PUR material of the tow chain, combined with whether the need for twisted pairs, shielding, single and double jacket and other factors to determine the specific model, and finally according to the number of cores and core cross-sectional area mm2 to determine the specific specifications, such as: High tow chain twisted single protective belt shield 2*0.75mm2 Now more and more companies began to buy bending resistance, bending resistance, wear resistance, radiation resistance, waterproof, oil, cold and UV resistance of the tow chain cable, in the face of a wide variety of models and specifications of high flexible cable how to choose many people do not know, I hope Xiaobian share to help you.
