How to Use Drag Chain?

Nowadays, drag chains are used in various industrial equipment and power places. The biggest feature of this kind of cable is that it is very flexible. When using drag chain cables, they are usually placed in tow chain boxes. It is convenient for people to organize and can effectively extend its service life.

How to use chain cable?

• The towline cable cannot be twisted, that is, the cable cannot be unwound from one end of the cable drum or cable reel. Instead, the cable reel or cable reel should be rotated to unwind the cable. If necessary, the cable can be unrolled or suspended. The cable for this occasion can only be obtained directly from the cable roll.
• Attention must be paid to the minimum bending radius of the cable.
• The cables must be laid loosely side by side in the drag chain, arranged separately as much as possible, separated by spacers or penetrated into the separation cavity of the bracket void, the gap between the cables in the drag chain should be at least 10% of the cable diameter.
• The cables in the drag chain must not touch each other or be bundled together.
• Both points of the cable must be fixed, or at least the moving end of the drag chain must be fixed. Generally, the distance between the moving point of the cable and the end of the drag chain should be 20-30 times the diameter of the cable.
• Ensure that the cable moves completely within the bending radius, that is, it cannot be forced to move. In this way, the cables can be moved relative to each other or the guiding device. After a period of operation, it is best to check the position of the cable. This inspection must be performed after the push-pull movement.

If the drag chain breaks, the cable also needs to be replaced, because damage caused by excessive stretching cannot be avoided.

How to install the wire and cable in the drag chain and whether the cable can be fixed is the concern of many engineering and technical personnel. ATO will tell you the fixing method of the wire and cable for the drag chain and the precautions when fixing it.

If the cable drag chain cable is stretched by tension during wiring, it will friction with the inner wall of the drag chain and cause the sheath to wear. On the contrary, if the wiring is too loose, it will also cause friction with the inner wall of the drag chain, causing the sheath to wear, and it will easily be entangled with other cables. The wiring length of the drag chain cable should be set to just pass the center line of the drag chain. In addition, if the moving part of the drag chain cable is fixed, the bending stress will not be dispersed and absorbed. The fixed part of the cable should be set at both ends of the drag chain.

5 Tips for fixing drag chain

(1) Properly select the length and bending angle of the cable to maintain the degree of freedom of the bending part of the cable.

(2) Keep the degree of freedom of the bending part of the cable when there are multiple cables, especially the combination of cables with different outer diameters.

(3) Do not bend excessively near the tied part

(4) When installing the connector, it needs to be supported by a sleeve or shell.

(5) Prevent the root of the connector from leaking into the cable.
