Medium Voltage Equipment: Supply to switchgear, transformers, and industrial motors.
Indoor and Outdoor Installations: Resistant to moisture, dust, and mechanical impact.
Real Indonesian Use Case: Grasberg Mine, Papua
In Papua’s Grasberg underground mine, FG7H1OAR 6/10kV cables were deployed to power tunneling machines under extreme mechanical stress. The steel wire braid armour protected the cable from abrasion against rock walls, while the PVC sheath allowed long-term exposure to high humidity without degradation.
How Does FG7H1OAR Compare with Other MV Mining Cables?
Feature | FG7H1OAR | Standard XLPE MV Cable | Reeling Cable |
|---|---|---|---|
Voltage Range | 3.6/6 & 6/10 kV | 6/10 kV | 3.6/6 kV |
Flexibility | High | Medium | Very High |
Flame Retardant | IEC 60332-1-2 | IEC 60332 | IEC 60332 |
Mechanical Protection | Steel wire braid | None or light armouring | Reinforced |
Indoor/Outdoor | Yes | Limited outdoor | Limited outdoor |
Ideal Use | Tunneling & underground mining | Fixed distribution | Mobile equipment |
FG7H1OAR combines flexibility, mechanical protection, and flame retardancy, making it ideal for medium-voltage industrial environments with high mechanical stress.
Frequently Asked Questions (FAQ)
Can FG7H1OAR cables be used in open-pit mines?
Yes, the cables are suitable for outdoor applications, including open-pit mining. However, for extreme sunlight exposure, additional UV protection is recommended.
How does FG7H1OAR differ from standard XLPE MV cables?
FG7H1OAR uses HEPR insulation for superior flexibility and abrasion resistance, while standard XLPE cables are stiffer and less suited for bending-intensive applications.
What maintenance is required for FG7H1OAR in underground mining?
Routine inspection of the PVC sheath and steel wire armour is sufficient. Look for cuts, abrasions, or heat damage. Voltage drop monitoring is recommended for long cable runs.
Can these cables handle short-circuit events?
Yes. The maximum short-circuit temperature is +250°C. Correctly sized cables, according to cross-section and load, can safely handle short-circuit conditions.
What is the recommended bending radius for installation?
Fixed: 6× overall diameter
Flexed: 10× overall diameter
Are FG7H1OAR cables flame-retardant?
Yes. They comply with IEC/EN 60332-1-2, ensuring reduced fire propagation in case of an incident.
