Supply of Pur drag chain cables

Supply of Pur drag chain cablesIntroduction:

Multiple strands of fine twisted and precision twisted bundles of first grade oxygen free copper wire are used as conductors, complying with DIN VDE 0295 grade 6. PVC T12 insulation is selected in accordance with DIN VDE 0281 part 1, and PVC sheath TM2 is selected in accordance with DIN VDE 0281 part 1. Special structural design, mechanical and electrical performance calculations, and simulation tests are conducted for usage scenarios. Reasonable structural design, strict material selection, sophisticated production and processing, and strict quality control procedures ensure that the product performs well in practical applications.

Introduction to drag chain cable:
The drag chain cable has a highly flexible characteristic and is widely used as a control connection line. In control units with bending requirements, it is specifically designed for situations where the cable can maintain soft movement while continuously bending and freely moving without tension or forced movement in drag chain systems. Characteristics of drag chain cable:
Drag chain cables can be customized with colored or coded cores according to customer requirements. Good mechanical performance and high flexibility.
When used for towing chains, it is designed to have a service life of 3 million cycles of bending and has been effectively validated in practical use.

Supply of Pur drag chain cablesInstallation precautions

1. The laying of drag chain cables cannot be twisted, that is, the cable cannot be untied from one end of the cable drum or cable reel. Instead, the drum or cable reel should be rotated first to unfold the cable, and if necessary, the cable can be unfolded or hung up. The cable used for this occasion can only be obtained directly from the cable reel.

2. Attention must be paid to the minimum bending radius of the cable, and the installation radius should not be less than 6 times the diameter of the cable.

3. The cables must be laid loosely side by side in the drag chain, separated as much as possible, separated by spacers or inserted into the separation holes of the bracket. The gap between the cables in the drag chain should be at least 10% of the cable diameter.

4. The cables in the drag chain must not come into contact with each other or get stuck together.

5. Both points of the cable must be fixed, or at least fixed at the moving end of the drag chain. The distance between the moving point of a general cable and the end of the drag chain should be 20-30 times the diameter of the cable.

6. Please ensure that the cable moves within the bending radius and cannot be forced to move. In this way, the cables can move relative to each other or to the guiding device. After a period of operation, it is best to check the position of the cable. This inspection must be conducted after the push-pull movement.

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