Case Study on Optimization of Mobile Equipment Cable Solution in Open-Pit Mine

The mobile equipment cables in an open-pit coal mine are often damaged due to frequent bending, dragging, and rolling, resulting in frequent equipment shutdowns, which seriously affects production efficiency. In addition, the harsh natural environment of the mine, such as heavy rain and high temperature, places higher requirements on the performance of the cable.

Project requirements

Abrasion resistance, flex resistance, and weather resistance: The cable must have excellent mechanical properties and be able to adapt to the harsh mining environment.

Vibration resistance: Mobile equipment will generate strong vibrations when working, and the cable must be able to withstand vibrations without damage.

Quick repair: Once the cable is damaged, it needs to be repaired quickly to reduce equipment downtime.

Shenxing Solution

Shenxing Company provides the mine with wear-resistant, flex-resistant and weather-resistant mobile equipment cable solutions. The specific features are as follows:

• High-strength steel wire braided outer sheath: The use of high-strength steel wire braided outer sheath (such as stainless steel braiding) significantly enhances the wear resistance and extrusion resistance of the cable.

• Special filling material: The cable is filled with highly elastic polymer materials (such as TPU) to improve the vibration resistance of the cable and reduce the damage to the internal conductor caused by vibration.

• Customized service: Provide customized cable solutions (such as flexible cables of different specifications) according to the specific power requirements and working environment of different equipment.

Technical advantages

• Strong durability:

The use of high-strength materials (such as armor layer) and special structural design (such as spiral sheath) prolongs the service life of the cable and reduces the frequency of replacement.

• Excellent anti-vibration performance:

The application of special filling materials (such as TPU) reduces the fatigue damage of the cable caused by vibration and improves the reliability of the cable.

Innovations

•Self-repairing sheath:

The cable sheath uses self-repairing materials (such as self-healing polymers), which can repair small damages to a certain extent and extend the service life of the cable.

•Intelligent monitoring system:

The built-in sensors (such as temperature sensors and vibration sensors) monitor the operating status of the cable in real time, warn of faults in advance, improve the reliability of the system, and provide data support for maintenance.

Practical application effect

• Wear resistance: Under frequent bending, dragging and rolling, the outer sheath of the cable (such as PVC sheath) remains intact and has no obvious signs of wear.

• Anti-vibration effect: Under the strong vibration of the mobile equipment, the internal conductor (such as tinned copper conductor) of the cable does not break or loosen, ensuring the continuity of power transmission.

• Intelligent monitoring: Through the intelligent monitoring system, several potential faults were discovered in time, and preventive maintenance was carried out to avoid unplanned downtime of the equipment.

Conclusion

The mobile equipment cable solution provided by Shenxing Company successfully solved the problem of frequent damage to mobile equipment cables in open-pit mines by adopting high-strength steel wire braided outer sheath, high-elastic polymer filling materials, quick connectors and other technologies. At the same time, the introduction of self-repairing sheath and intelligent monitoring system further improved the reliability and service life of the cable, providing a solid guarantee for the efficient operation of the mine.
