Understanding Medium-Voltage Reeling Cables with Fiber Optics

What Are Medium-Voltage Reeling Cables?

Medium-voltage reeling cables, such as the (N)TSCGEWOEU, are engineered for high-voltage applications (3.6/6 kV to 18/30 kV) under extreme mechanical stress. These cables are flexible, durable, and designed for motorized reeling systems, such as monospiral or level-wind reelers, commonly used in mining and heavy industry. The integration of fiber optics enables simultaneous power delivery and high-speed data transmission, making them ideal for modern industrial operations requiring real-time monitoring and control.

Benefits of (N)TSCGEWOEU Cables

1. Durability: The robust construction, including a polyester anti-torsion braid and flame-retardant, oil-resistant outer sheath, ensures longevity in harsh conditions like South African mines.

2. Flexibility: Class 5 copper conductors and EPR insulation allow the cables to endure continuous reeling and bending without degradation.

3. Integrated Data Transmission: Fiber optics enable real-time data transfer for monitoring equipment performance, enhancing operational efficiency.

4. Safety: Semiconductive layers and split earth conductors reduce electrical risks, critical in high-voltage applications.

5. Versatility: Available in multiple voltage ratings and core sizes, these cables suit diverse applications, from small cranes to massive excavators.

Installation and Maintenance Recommendations

Installation

• Reeling System Compatibility: Ensure the cable is compatible with monospiral or level-wind reelers. Verify the reel’s tension and speed settings to prevent overstretching.

• Bending Radius: Adhere to the minimum bending radius (typically 6–8 times the cable diameter) to avoid insulation damage.

• Environmental Considerations: Install in environments free from excessive heat or chemical exposure beyond the cable’s resistance capabilities.

• Professional Handling: Use trained technicians to install cables, ensuring proper grounding and connection to equipment.

Maintenance

• Regular Inspections: Check for abrasions, cuts, or sheath damage monthly, especially in high-stress reeling applications.

• Cleaning: Remove dust and debris from the cable surface to prevent degradation of the outer sheath.

• Tension Monitoring: Regularly calibrate reeling systems to maintain optimal tension, reducing wear.

• Fiber Optic Testing: Periodically test fiber optic performance to ensure data transmission integrity.

Usage Scenarios in South African Mining and Heavy Industry

South Africa’s mining sector, a cornerstone of the economy, relies heavily on robust infrastructure. The (N)TSCGEWOEU cables are ideal for:

• Deep-Level Mining: In gold and platinum mines, these cables power large excavators and conveyors while transmitting data for remote monitoring, improving safety and efficiency.

• Open-Pit Operations: In coal and diamond mines, the cables support spreaders and draglines, with fiber optics enabling real-time equipment diagnostics.

• Port and Logistics: Gantry cranes at ports like Durban use these cables for reliable power and data connectivity, handling heavy cargo loads.

Case Study: Enhancing Efficiency in a South African Platinum Mine

In 2024, a major platinum mine in Rustenburg faced challenges with frequent cable failures due to the abrasive environment and high mechanical stress. By upgrading to (N)TSCGEWOEU 12/20 kV cables (3×95+2×50/2+12×LWL), the mine achieved:

• Reduced Downtime: The cables’ durability minimized replacement frequency by 60%.

• Improved Monitoring: Fiber optics enabled real-time equipment performance tracking, reducing maintenance costs by 25%.

• Enhanced Safety: Flame-retardant sheaths and robust grounding reduced electrical hazards, aligning with South Africa’s stringent mining safety regulations.

This case underscores the cables’ role in addressing current industry trends, such as the push for automation and real-time data in South African mining.
