What are the common faults of drag chain cables?

With the wide application of drag chain cables in modern construction, once a fault occurs, it will have a serious impact on people’s lives and enterprise production. How to avoid the failure of the drag chain cable has become an imminent problem in the power sector. The editor of Yuanfu Lianying believes that strengthening the maintenance of towline cables is the key to solving the failure of towline cables. To do a good job in the maintenance of the towline cable, it is necessary to understand the cause of the towline cable failure, so as to avoid the towline cable failure at the root cause. ,
The reasons for the common faults of drag chain cables are as follows:

Insulation is damp: the cable’s protective layer will be broken due to the poor manufacturing process of the cable; the sealing of the cable terminal joint is not enough; the cable protective sleeve is pierced by objects or corroded during the use of the cable. These are the main reasons why cable insulation gets wet. At this time, the insulation resistance decreases and the current increases, causing a power failure problem.

External force damage: External force damage is the most common cause of failure in cable faults. After the cable is damaged by external force, there will be a large-scale power outage accident. For example, during the construction of underground pipelines, the cables are pulled and broken due to the excessive traction force of the construction machinery; the cable insulation and shielding layers are damaged due to excessive bending of the cables; the cables are cut and stripped excessively and the knife marks are too deep. These direct external force factors will cause certain damage to the cable.

Long-term overload operation: The power cable is in a high-current operation environment for a long time. If there are impurities or aging in the line insulation layer, plus the impact of overvoltage caused by external factors such as lightning, overload operation will generate a lot of heat, which is very easy to A power cable failure has occurred.

Chemical Corrosion: Long-term current exposure will generate a lot of heat from the cable insulation. If the cable insulation work is in a bad chemical environment for a long time, its physical properties will be changed, the cable insulation will be aged or even lose its effectiveness, and power failures will occur.

The analysis of the causes of common faults of drag chain cables will be introduced here first, hoping to help you.
