Description

Technical Field

[0001] This utility model relates to the field of drag chain cable technology, and in particular to a high-life, bend-resistant drag chain cable. Background Technology

[0002] Drag chain cables are highly flexible special cables that can move back and forth with a drag chain without easily wearing out. They are also commonly known as drag cables or tank chain cables. With the increase in electrical equipment, many devices require drag chain cables that can bend and move repeatedly. Although the drag chain cables currently in use can meet normal usage requirements, they still have certain defects in actual use. For example, the drag chain cables currently in use have low toughness and unsatisfactory bending resistance. After long-term bending, the cable surface is prone to breakage, which reduces the cable insulation performance and affects the cable's service life. Improvements are needed. Therefore, a high-life bending-resistant drag chain cable is proposed. Utility Model Content
