[0002] Traction chain cable is a highly flexible special cable that can move back and forth with the drag chain without being easily worn, and is usually also called drag cable, tank chain cable. In occasions where equipment units need to move back and forth, in order to prevent cable entanglement, abrasion, pulling off, hanging and scattering, the cable is often placed in the cable drag chain to protect the cable, and the cable can also move back and forth with the drag chain.
