SHD-GC Mining Cable (Heavy Duty Shielded with Ground Check, 2kV-25kV)
Farwalk’s SHD-GC Mining Cables are the impenetrable power veins of the subterranean world. Engineered for the absolute maximum mechanical stress of surface and underground mining, these cables combine flexible copper shielding with an integrated Ground Check (GC) conductor, ensuring both relentless power delivery and fail-safe personnel protection in the presence of continuous movement and abrasion.
Manufactured to meet or exceed ICEA S-75-381 / NEMA WC 58 and CAN/CSA-C22.2 No. 96 standards. The internal assembly features Class 5 or Class 6 fine-stranded tinned copper conductors, insulated with Ethylene Propylene Rubber (EPR). Each core is individually shielded with a tinned copper braid. The system is fortified by a reinforced double-pass Chlorinated Polyethylene (CPE) or Neoprene jacket.
The definitive choice for heavy mining equipment including electric shovels, draglines, continuous miners, and massive drills. Specifically designed for applications where cable integrity must be monitored in real-time to prevent catastrophic ground-fault hazards in damp, high-vibration mining environments.
• Voltage Rating: 2kV, 5kV, 8kV, 15kV, 25kV
• Core Construction: 3 Conductors + 2 Grounds + 1 Ground Check
• Insulation: 90°C EPR (Heavy Duty)
• Shielding: Individually Shielded (Braid or Tape)
• Jacket: Heavy-duty CPE or Neoprene (Oil, UV, Flame Resistant)
• Temp. Range: -40°C to +90°C
1. Conductor: Fine-stranded flexible tinned copper, Class 5 or Class 6 per IEC 60228.
2. Conductor Shield: Semi-conductive tape or compound (for voltage stress control).
3. Insulation: High-grade Ethylene Propylene Rubber (EPR).
4. Grounding (GC): Insulated Ground Check conductor for continuous monitoring of ground integrity.
5. Ground Conductors: Two or more flexible bare or tinned copper grounding wires.
6. Metallic Shield: Tinned copper wire braid or tape over each insulated core.
7. Outer Jacket: Heavy-duty, reinforced Chlorinated Polyethylene (CPE) or Neoprene compound.
• Integrated Ground Check (GC): Features a specialized center monitoring core that provides fail-safe circuit interruption if ground continuity is compromised, essential for underground safety.
• Extreme Torsional Endurance: Specifically engineered with a shorter lay length and specialized braiding to withstand constant reeling, twisting, and dragging across jagged rock surfaces.
• Industrial Fortification: The extra-thick, double-pass vulcanized jacket provides the highest level of resistance to mineral oils, acid mine water, flame, and high-impact crushing.
• MSHA Certified Readiness: Our SHD-GC cables meet the most rigorous flame and durability requirements of global mining authorities.
• Master Batch Compounding: We utilize proprietary CPE rubber blends that remain flexible at -40°C while resisting the abrasive ‘cutting’ effect of iron ore and coal debris.
• Zero-Failure Manufacturing: 100% of reels undergo partial discharge and high-voltage corona testing to ensure absolute reliability in the world’s deepest shafts.
