Project Background
The cables of the hoisting system of a deep copper mine have been aging and experiencing insulation degradation under long-term high-load operation, resulting in frequent tripping, which seriously affects the production efficiency of the mine. In addition, there is a large amount of corrosive gas and dust in the mine, which poses a great threat to the life of the cable.
Project requirements
In order to meet these challenges, the project puts forward the following specific requirements:
• High temperature resistance, corrosion resistance, and wear resistance: The cable needs to be able to work stably in the high temperature, high humidity, and highly corrosive environment in the mine, and have good mechanical properties to cope with frequent bending and stretching.
• Low smoke and halogen-free, environmentally friendly: The cable material must be low smoke and halogen-free to ensure that the amount of harmful gases generated during combustion is minimized to ensure the safety of mine workers.
• Signal transmission function: The cable must not only undertake the task of power transmission, but also integrate signal transmission function to support remote monitoring and fault diagnosis of the lifting system.
Solution
Shenxing Company tailored a new type of lifting system cable for the mine, with the following specific features:
Material selection:
• Insulation material: Cross-linked polyethylene (XLPE) is used as the insulation material, which has excellent heat resistance and anti-aging ability.
• Sheath material: Special alloy sheath is selected to enhance the corrosion resistance and wear resistance of the cable.
Function integration: Power transmission and signal transmission: The optical fiber core is integrated inside the cable to realize the dual transmission of power and signal, simplify the system structure, and reduce maintenance costs.
Intelligent monitoring: Real-time monitoring of the cable operation status through optical fiber technology, fault warning, and improved system reliability.
Environmental protection and safety: Low smoke halogen-free materials, low smoke halogen-free materials are selected to ensure that the amount of harmful gases generated by the cable during combustion is minimized to ensure the safety of mine personnel.
Comprehensive solution:
• Professional cable laying solution: Provide professional cable laying guidance to ensure the correct installation of cables in complex environments.
• Maintenance plan: Develop a detailed maintenance plan, including regular inspections, troubleshooting, etc., to ensure the long-term and reliable operation of the cable.
Technical advantages
• Multifunctional integration: Power transmission, signal transmission and optical fiber communication functions are integrated into one, which simplifies the system structure and reduces maintenance costs.
• Intelligent monitoring: Use optical fiber technology to monitor the operating status of the cable in real time, realize fault warning, and significantly improve the stability and safety of the system.
• Environmental protection and safety: The selection of low-smoke and halogen-free materials protects the life safety of mine workers to the greatest extent.
• Long life cycle: Through high-quality materials and careful design, the service life of the cable is greatly extended and the replacement frequency is reduced.
Innovation points
Fiber-optic composite cable:
Innovatively integrates power transmission and fiber-optic communication functions in the same cable, realizing synchronous transmission of electrical and optical signals, and improving the efficiency and reliability of the system.
Intelligent management:
Introducing Internet of Things technology to realize remote monitoring and fault diagnosis of cable operation status, providing an intelligent management method for mines.
Application scenarios
• High temperature environment: The cable can still maintain good electrical performance in a continuous high temperature environment of up to 100°C.
• High humidity environment: The cable still exhibits excellent insulation performance in an environment with a relative humidity of more than 95%.
• Corrosive environment: The cable's corrosion resistance has been verified in an environment containing acidic gas and salt spray.
• Abrasive environment: The mechanical strength and wear resistance of the cable are guaranteed under frequent bending and stretching.
Maintenance and support
• Regular inspection: It is recommended to conduct a cable operation status inspection once a quarter to promptly detect and eliminate hidden dangers.
• Fault handling: Provide a detailed fault handling manual to ensure that on-site technicians can respond and solve problems quickly.
• Lifetime service: Provide lifelong technical support and services to ensure that customers receive continuous help during use.
