1. Cables shall not be twisted when laying and shall not be unwound from either end of the drum or cable tray. Instead, the cable shall be unfolded by rotating the drum or cable tray first, and the cable may be unfolded or hung up if necessary.Cables used for this purpose can only be obtained directly from the cable coil.

2. Note the minimum bending radius of the cable.

3. Cables must be laid side by side, loosely in the trailing chain, as far apart as possible, separated by spacers or inserted into the separation voids in the empty brackets of the supports. The voids between cables in the trailing chain shall be at least 10% of the cable diameter

4. Cables in the tow chain shall not touch or get stuck together.

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

6. Make sure that the cable moves completely within the bending radius, that is, it cannot be forced to move.

Understanding these knowledge, in the daily installation, use process can effectively avoid the damage of the cable and drag chain, prolong the service life.
