The reasons for the aging of drag chain cables are as follows:
The cable is damp: the general use environment is relatively humid, or directly in the water, and the other is found at the joint of the cable in the pipe. If the connector of the cable is unqualified or in a humid environment, a lot of water vapor will cause damage to the cable. After the cable is wet, it will affect the insulation of the cable, resulting in failure.
External force damage: The external force damage of towline cables is generally caused by physical damage caused by mechanical equipment. During the operation of machinery and equipment, the cable must constantly adapt to repeated actions such as bending, dragging, and twisting. Over time, the towline cable is prone to external damage. The aging and cracking of the sheath may even cause the inner core to break if care is not taken to maintain it.
Chemical corrosion: This is a relatively common situation. The operating environment of the drag chain cable is acidic and alkaline. During the operation, the acid and alkali will corrode the protective layer of the cable to varying degrees. If the protective layer is damaged, the drag chain will be damaged. The insulation of the cable is greatly reduced, and dangers such as leakage are prone to occur.
Long-term overload operation: During long-term overload operation, over-temperature will accelerate insulation aging and even destroy insulation. Especially in hot summer, the temperature rise of the cable often leads to the first breakdown of the cable insulation, so there are more cable failures in summer.
The relevant content will be shared here first. External force damage, insulation, moisture, chemical corrosion, long-term overload operation and cable joint failure are several reasons for improper use of the towline cable aging and failure. These things should be avoided as much as possible to ensure the towline. normal service life of the cable.
