1. The weight of the cable in the industrial control cable drag chain should be evenly distributed, so as to avoid accidents caused by uneven weight during operation, and the principle of distributing the cable is that the heavier one is located on both sides and the lighter one is located in the middle. All industrial control cables must be securely fastened to one end of the energy chain, which ensures that the cables can be safely moved to the other end with other devices.
2. The cables are different, according to the principle of arranging the cable protection chain according to the different cables, when the flat cable and the round cable are mixed in the drag chain, the cables must be loosely installed. Fixings should be installed on both sides of the cable, and round cables of different sizes should be avoided as much as possible.
3. When the conductive multi-core cable is small (less than 10mm), in order to prevent it from loosening in the cable tray, it is recommended to use the guide tube as the carrier.
4. The cable in the industrial control cable threading chain must run smoothly and straight, and cannot be twisted or curled, and the cable must be rotated and opened from the cable reel or reel, and cannot be extracted from the top twisted.
