Cable drag chains are named because wires and cables are placed inside the drag chain box. In situations where equipment units need to move back and forth, to prevent cables from tangling, wearing, pulling off, snagging, and becoming messy, cables are often placed in drag chains to protect them, and the cables can also move back and forth with the drag chain. It is a high-flexibility cable that can move back and forth with the drag chain without being easily worn out.
The conductor uses finely twisted fine copper wires, and ordinary cables also use fine copper wires. For the same cross-section of core wires, the single wire diameter in the drag chain cable conductor is smaller than that of ordinary wires and cables. To ensure the stability of the conductor's physical and electrical properties, multi-head drawing 4N conductors are generally used. The conductor is bright and shiny with good toughness; low resistivity, and the wire does not heat up under rated load for a long time. It is often used in automation equipment. It has good flexibility, bending resistance, and strong wear resistance. If used in combination with standard drag chains, it can not only facilitate organization but also more effectively extend its service life.
Now let's talk about how to correctly use cable drag chains:
1. The cable should not be twisted during laying, that is, do not unwrap the cable from one end of the cable reel or cable drum. Instead, first rotate the reel or drum to unfold the cable. If necessary, the cable can be unfolded or hung up. Cables used in this situation can only be taken directly from the cable reel;
2. Pay attention to the bending radius of the cable;
3. The cables must be laid loosely and side by side in the drag chain, separated as much as possible, using separators or passing through the separation holes in the bracket gaps. The gap between cables in the drag chain should be at least 10% of the cable diameter;
4. Cables in the drag chain must not touch each other or be bundled together;
5. Both ends of the cable must be fixed, or at least the moving end of the drag chain must be fixed. Generally, the distance from the cable's moving point to the end of the drag chain should be 20-30 times the cable diameter;
6. Ensure that the cable moves completely within the bending radius, that is, do not force movement. This allows relative movement between cables or between cables and the guide device. After a period of operation, check the position of the cables. This check should be done after push-pull movement;
To ensure stable operation of equipment and extend the service life of cable drag chains, please follow the above usage specifications when using them.
