Medium-voltage flexible cables are critical components in modern mining, bulk material handling, and heavy industrial systems. Among them, Feichun (N)TSCGEWOEU 6–35 kV medium voltage flexible cables for semi-flexible installation are designed for demanding environments where electrical performance, mechanical durability, and operational safety must coexist.

What Standards and Certifications Does the (N)TSCGEWOEU Cable Meet?

The cable complies with internationally recognized standards:

DIN VDE 0250-813 – Medium-voltage flexible cables
DIN VDE 0298-4 – Electrical parameters
DIN EN / IEC 60811-404 – Chemical and mechanical testing
DIN EN 50525-2-21 – Material behavior
DIN EN / IEC 60332-1-2 – Flame retardancy
GOST Fire Certificate – Russian Federation approval

This compliance makes the cable suitable for export-oriented mining and industrial projects, including those in Africa.

What Are the Key Electrical and Thermal Performance Parameters?

What Voltage Range Is Available?

The (N)TSCGEWOEU series covers:

3.6/6 kV up to 20/35 kV
Nominal voltages from 6 kV to 35 kV

What Are the Thermal Limits?

Max conductor temperature (normal): 90 °C
Short-circuit temperature: 250 °C
Fixed installation: -40 °C to +80 °C
Flexible installation: -25 °C to +60 °C

These limits ensure reliability in both cold and hot mining regions.

How Does the (N)TSCGEWOEU Cable Perform Mechanically?

Is the Cable Resistant to Torsion and Tension?

Yes:

Torsional stress: ±100°/m
Permanent tensile strength: 15 N/mm²

What Is the Minimum Bending Radius?

According to VDE 0298-3:

This makes the cable suitable for installations with moderate movement and alignment changes.

Which Applications Are Best Suited for (N)TSCGEWOEU Cables?

Where Is This Cable Typically Installed?

Along conveyor belts, including shiftable systems
Material handling equipment
Cable booms and vertical connections between machine levels
Submersible pump units (up to 10 m water depth)

Why Is Semi-Flexible Installation Ideal Here?

These applications involve:

Occasional movement
Vibration
Mechanical stress
But do not require continuous reeling, making (N)TSCGEWOEU a cost-effective and durable choice.

How Does (N)TSCGEWOEU Compare with Other Medium-Voltage Flexible Cables?

Comparison Table

Feature	(N)TSCGEWOEU	Standard MV PVC Cable	Fully Reeling MV Cable
Voltage range	6–35 kV	Up to 15 kV	Up to 36 kV
Insulation	EPR	PVC	EPR
Flexibility	Semi-flexible	Limited	High
Oil resistance	Excellent	Moderate	Excellent
Continuous reeling	No	No	Yes
