As shown, the (N)TSCGEWOEU LWL stands out for higher voltage ratings, flexibility, and integrated data communication, which are critical for modern mining operations.
What Are Typical Applications of the (N)TSCGEWOEU LWL Cable in South Africa?
In South African mining environments, this cable is widely used for:
Large Excavators and Draglines: Powering heavy machinery with dynamic movements on mono-spiral reels.
Mobile Crushers and Dumpers: High-current supply for equipment requiring frequent repositioning.
Material Handling Systems: Integrated fiber-optics enable remote monitoring and predictive maintenance.
Harsh Environments: Open-cast mines with exposure to UV, oil, seawater, and extreme temperatures.
Case Study: Open-Cast Platinum Mine, South Africa
A major platinum mine installed the 20/35 kV variant to supply power to mobile crushers. The integration of fiber-optics allowed the operation team to monitor real-time power load and equipment position. This minimized downtime and reduced maintenance costs by 18% annually.
What Are the Safety and Fire Performance Standards?
The (N)TSCGEWOEU LWL cable meets multiple international safety standards:
DIN VDE 0250-813 / EN 50525-2-21: General electrical standards
DIN EN 60811-404 / IEC 60811-404: Chemical resistance and material aging
DIN EN 60332-1-2 / IEC 60332-1-2: Flame retardant performance
GOST-R/-K/-B: Fire certificate approvals (Russia)
These standards ensure that the cable is safe for both operators and equipment, even in fire-prone mining environments.
What Are the Benefits of Integrated Fiber-Optics in MV Reeling Cables?
The integrated fiber-optics (LWL) provide several advantages:
Real-Time Monitoring: Transmission of electrical parameters from sensors to control rooms.
Predictive Maintenance: Early detection of overloads, wear, or mechanical stresses.
Data Communication: Connects SCADA systems, GPS, or telemetry for mobile mining equipment.
Cost Efficiency: Reduces downtime and avoids separate communication cabling.
By combining power and data in a single cable, mines simplify infrastructure while enhancing operational safety.
How Do I Choose the Right Cable Size for My Application?
Selecting the correct (N)TSCGEWOEU LWL variant depends on:
Rated voltage of equipment (6–35 kV)
Current carrying capacity requirements
Reel type (mono-spiral or cylindrical)
Distance between power source and equipment
Environmental conditions (UV, oil, seawater)
Example: A 15 kV mobile crusher requiring 250 A would benefit from a 3x70+2x50/2+LWL variant, providing sufficient current capacity and mechanical strength for high-speed reeling.
FAQ: Frequently Asked Questions About (N)TSCGEWOEU LWL Cables
Can I Use These Cables in Underground Mines?
Yes, but ensure ambient temperature and chemical resistance match underground conditions. Cable variants are rated for flexible operation from -30°C to 80°C.
How Do I Maintain the Cable on a Reeling System?
Regularly inspect for abrasion or mechanical damage.
Monitor torsion and bending radii during operation.
Keep reels clean and aligned to prevent uneven winding.
