Introduction:
Trailer chain cable: in the equipment unit needs to move back and forth occasions, in order to prevent the cable entanglement, wear and tear, pull off, hanging and scattered, often put the cable into the cable chain, the cable to form a protective, and the cable can be realized with the chain to move back and forth, this can be followed by the chain to move back and forth and is not easy to wear and tear of the high-flexibility of the special cable will be called the trailing chain cable, usually also known as the trailing cable, tank cable, the cable can also be referred to as the towing cable. Can be called drag cable, tank chain cable.
Drag chain cable general requirements:
1, drag chain cable laying can not be twisted, that is, not from the cable reel or cable tray at one end of the cable to unlock the cable, and should be the first to rotate the reel or cable tray will be the cable unfolding, 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, must pay attention to the minimum bending radius of the cable. (The information can be found in the flexible drag chain cable selection table).
3, the cable must be loosely laid side by side in the drag chain, as far as possible, arranged separately, separated by spacers or threaded into the bracket gap in the separation of the cavity, in the drag chain between the cable gap should be at least 10% of the diameter of the cable .
4, the cables in the drag chain shall not touch each other or trapped together.
5, both points of the cable must be fixed, or at least at the moving end of the drag chain must be fixed. Generally the distance of the moving point of the cable from the end of the drag chain should be 20-30 times the diameter of the cable.
6, please make sure that the cable moves completely within the bending radius, i.e. it must not be forced to move. So that the cable can move relative to each other or to the guiding device. After a period of operation, it is advisable to check the position of the cable. This check must be carried out after the push-pull movement.
7. If the drag chain breaks, the cable also needs to be replaced because damage caused by overstretching cannot be avoided.
