Under the premise of complying with regulations such as small radius, environment, drag chain speed, and drag chain travel, the service life of drag chain cable can reach 3-5 years or even longer. Why is the lifespan significantly shorter than the estimated value in practical applications? Here, we will provide a detailed analysis of the causes of common faults.
The outer sheath of the ドラッグチェーンケーブル is broken:
1. The laying and installation of highly flexible drag chain cables are not standardized
he installation and laying of highly flexible cable have strict requirements, and the outer diameter of the cable should match the depth of the drag chain; A certain clearance distance should be maintained between cables to prevent cable friction and premature damage during movement; 10% of the cable length should be reserved to prevent the cable from being pulled too tightly during movement.
2. Improper selection
The bending radius of the Flex cable should not be less than 7.5 times the outer diameter of the cable. The smaller the bending radius, the shorter the service life of the cable.
3. Poor quality of high flexibility cable sheath
The outer sheath material of the ドラッグチェーンケーブル is not made of good materials with wear resistance, oil resistance, flame retardancy, tear resistance, etc., which greatly shortens the service life due to secondary charging.
4. Using inferior drag chains
Poor quality drag chains increase friction between cables and drag chains, leading to a shortened lifespan of cables.
Core wire damage of drag chain cable:
1. The production process does not comply with the specifications or the structural design is unreasonable, resulting in excessive friction coefficient between the core wire and the core wire, as well as between the core wire and the sheath, which shortens the life of the core wire due to premature damage.
2. Improper selection of core wire insulation materials or poor material properties can result in the mechanical, flexural, and tensile properties of the insulation not meeting the standards.
3. Improper selection of conductor cross-sectional area in フレキシブルワイヤー can lead to overheating of the wire core, melting of the insulation layer, and damage to the core wire, resulting in open or short circuits of the core wire, which can cause equipment signal interruption or even equipment burnout, causing serious damage to the equipment.
4.The wire core has not been twisted back. During normal production of フレキシブルケーブル, when multiple copper wires are twisted together, they need to be twisted back to eliminate internal stress. When the core wire is twisted into a cable, it should also be twisted back to ensure no rebound or twisting.
The non twisting ドラッグチェーンケーブル looks round and smooth, but each wire inside holds a torque. After several times of operation, the core wire is automatically twisted and rolled, and the internal core is twisted into Fried Dough Twists. Causing rapid fatigue fracture of the conductor, resulting in bulging and deformation of the entire cable.
