MP-GC Mine Power Feeder Cable (Heavy-Duty with Ground Check, 5kV-35kV)
Farwalk’s MP-GC Mine Power Feeder Cables are the high-voltage master arteries for heavy mining infrastructure. Specifically engineered for main power distribution in both underground mines and massive open-pit pits, these cables utilize a specialized Ground Check (GC) pilot wire to provide real-time grounding continuity monitoring. Built with EPR insulation and a vulcanized CPE jacket, they deliver safe and relentless energy to the world’s deepest operations.
Manufactured in accordance with ICEA S-75-381 / NEMA WC 58 and UL standards. The core features Class B or Class C stranded tinned copper conductors, insulated with premium Ethylene Propylene Rubber (EPR). The assembly includes two flexible grounding conductors and one insulated Ground Check (GC) pilot wire, protected by a heavy-duty reinforced Chlorinated Polyethylene (CPE) outer jacket.
The primary choice for main power distribution circuits between substations and mine equipment, or as feeders for borehole and vertical shaft installations. Ideally suited for fixed or semi-portable applications where high-voltage safety and maximum mechanical protection are non-negotiable.
• Voltage Rating: 5kV, 8kV, 15kV, 25kV, 35kV
• Core Configuration: 3 Conductors + 2 Grounds + 1 Ground Check
• Insulation: 90°C EPR (Heavy Duty)
• Shielding: Non-shielded (Standard MP) or Shielded (SHD-MP) options
• Jacket: Reinforced CPE (Abrasion, Flame & Mine-Water Resistant)
• Compliance: MSHA, ICEA, ASTM
1. Conductor: Stranded flexible tinned copper, Class B or Class C per ASTM.
2. Conductor Shield: Semi-conductive compound for voltage stress control.
3. Insulation: High-grade Ethylene Propylene Rubber (EPR).
4. Grounding (GC): One insulated Ground Check (GC) conductor for continuous monitoring.
5. Ground Conductors: Two bare flexible copper grounding wires.
6. Tape Barrier: Polyester tape for clean stripping and core stability.
7. Outer Jacket: Heavy-duty reinforced Chlorinated Polyethylene (CPE) or Neoprene.
• High-Voltage Feed Capacity: Engineered to serve as the primary power trunk (up to 35kV) for both deep-shaft underground and open-pit mining environments.
• Fail-Safe GC Monitoring: Includes an integrated Ground Check pilot wire, enabling specialized relays to trip power if grounding continuity is lost, ensuring personnel safety.
• Heavy-Duty Fortification: The vulcanized CPE jacket provides the highest industrial defense against abrasion, tearing, acidic mine water, and mineral oils.
• MSHA Certified Readiness: Our MP-GC cables are strictly manufactured to meet global mining safety codes, including MSHA flame-retardant standards.
• Precision CV Vulcanization: Using high-pressure continuous vulcanization ensures a perfectly uniform, perfectly bonded jacket with zero air pockets.
• site-Proven Reliability: Successfully deployed in the world’s most aggressive mining basins, Farwalk provides the technical dossiers required for immediate site approval.
