Nowadays, drag chain cables are used in various industrial equipment and power places. The big characteristic of this cable is its good flexibility, and it is usually placed in the drag chain box when using this cable, so it is convenient for people to sort out and can effectively prolong its service life. However, the core is often broken in the process of use. The following Xiaobian will summarize several common core breaking reasons of drag chain cable for you!

The first reason is the winding mode of the strand. The strand structure shall be designed according to the motion state. When it is wrapped around the tensile center, it must be * * * to ensure that it is * * * good intersection pitch, and the tensile center is also required to be * * * stable. In addition, the hinge process must ensure that there is * * * small friction. For example, its outer diameter should use * * * good diameter, and the movement state of the wire core should also ensure * * * good, otherwise the cable core will be broken.

The second reason: improper selection of conductor structure. Because the drag chain cable often needs to be moved repeatedly during use, or most cables are used in places that need to be dragged repeatedly, there are also great physical performance requirements for the conductor inside this cable. For example, the conductor inside it must have high flexibility. Generally, the flexibility of the cable is improved with the decrease of the conductor diameter, but the conductor with too small diameter can not be selected when selecting the conductor, because too thin will lead to mutual winding of the cable. In fact, China's cable network has long been calculated through a series of experiments, so it can be selected directly according to this data. Cables with good diameter often have good tensile properties and flexibility.

The third reason is the selection of raw materials. Generally, different raw materials are used when making cables, and their properties are also different. For example, some cables have better resistance to low temperature, while some cables have relatively low cost and so on. However, no matter what kind of cable is used, its sheath must ensure high wear resistance, and there are certain requirements for its flexibility and support performance.

The above are the three common causes of broken core of drag chain cable. In addition, if the cable is not installed according to the normal operation, it will also lead to broken core, such as overload operation of the cable for a long time during installation, etc. Therefore, if you want to avoid cable core breakage, you should pay special attention to all links of installation and use.
