What Is the Feichun (N)TSCGEWOEU Cable and Why Is It Used in Mining?
The (N)TSCGEWOEU cable is a flexible medium-voltage reeling cable designed for mobile equipment in open-pit mining operations. Its key feature is flexibility combined with high mechanical strength, making it suitable for installation on mono-spiral and cylindrical reels.
South African mining environments, particularly in gold, platinum, and coal open-cast mines, present harsh operating conditions. Machines require cables that can endure:
Constant bending and twisting on reels
Exposure to oils, UV, and ozone
Mechanical abrasion
High short-circuit and operating temperatures
The Feichun (N)TSCGEWOEU meets these challenges while complying with DIN VDE 0250-813, EN 50525-2-21, and IEC 60811-404 standards, ensuring reliability and safety.
What Are the Thermal and Chemical Resistance Capabilities?
Mining environments often expose cables to extreme temperatures and harsh chemicals. The Feichun (N)TSCGEWOEU excels in these areas:
Temperature Range:
Fixed installation: -40 °C to 80 °C
Flexible operation: -30 °C to 80 °C
Short Circuit Tolerance: Up to 250 °C
Chemical Resistance:
Flame retardant (EN/IEC 60332-1-2)
Oil resistant
Ozone resistant
UV resistant
Sea water resistant
This combination allows cables to operate reliably under severe South African mine conditions, including exposure to sunlight, diesel fuel, and mining chemicals.
How Does Mechanical Performance Enhance Mining Safety?
Mechanical stress is a critical factor in reeling cables. The (N)TSCGEWOEU cable has been engineered to withstand:
Torsional Stress: ±100°/m
Permanent Tensile Strength: 20 N/mm² static, 25 N/mm² dynamic
Travel Speeds:
Rewinding: Up to 100 m/min
Reeling: Up to 120 m/min
Bending Radius:
Fixed: 6 × cable diameter
Flexible: 10 × cable diameter
S-type direction change: 20 × cable diameter
These mechanical specifications ensure that cables do not suffer fatigue or breakage during continuous operation on mobile reels in mines.
What Are Typical Applications of (N)TSCGEWOEU in South African Mining?
The cable is ideal for medium-voltage power supply to mobile mining equipment. Typical applications include:
Excavators: Supplying power to hydraulic and electric drives
Dumpers and Haulers: Ensuring continuous medium-voltage feed in opencast operations
Mobile Crushers: Powering high-demand crushing machinery
Material Handling Systems: For conveyors, stackers, and reclaimers in mining yards
Case Study: South African Gold Mine
At a gold mine in Gauteng, a fleet of 12 excavators was retrofitted with Feichun (N)TSCGEWOEU 12/20 kV cables on mono-spiral reels. Over 18 months, downtime due to cable failure reduced by 45%, demonstrating superior mechanical and chemical resistance compared to previous PVC-insulated cables.
How Does (N)TSCGEWOEU Compare with Other MV Reeling Cables?
A comparison of popular MV reeling cables shows the advantage of the (N)TSCGEWOEU design:

Frequently Asked Questions (FAQ)
What Is the Maximum Voltage for (N)TSCGEWOEU Cables?
The series supports rated voltages from 6 kV to 35 kV, making it suitable for most mobile mining machinery. Short-circuit test voltages range from 11 kV to 50 kV.
Can (N)TSCGEWOEU Be Used Outdoors in South Africa?
Yes. The cable’s UV, ozone, and sea-water resistance makes it ideal for outdoor exposure in open-cast mines.
How Do I Choose Between Different Cross-Sections?
The selection depends on machine power requirements and reel compatibility. For instance, a 3x150+3x95/3 mm² cable can carry up to 404 A, suitable for high-power excavators, while 3x50+3x25/3 mm² handles lighter equipment (~202 A).
Is (N)TSCGEWOEU Fire-Retardant?
Yes, the cable complies with DIN EN 60332-1-2 / IEC 60332-1-2, ensuring it will not propagate flames in case of fire.
How Does This Cable Handle Reeling Stress?
With torsional stress up to ±100°/m and bending radius flexibility, the cable is designed specifically for reeling applications, avoiding fatigue and premature failure.
Can This Cable Replace Older PVC MV Cables?
Yes, but operators must ensure reel compatibility and voltage rating match. Feichun (N)TSCGEWOEU offers superior mechanical and chemical resistance.
