Mining Cables – LV HV Flexible & Trailing Cables

Mining Cables — LV & HV Flexible Trailing Cables for Underground & Surface Mining

Our mining cables are purpose-engineered heavy-duty flexible power cables for the most demanding underground and surface mining environments. Designed to withstand continuous flexing, crushing, moisture ingress, chemical exposure, and severe mechanical abuse, they are the lifeline of mining machinery — from continuous miners and longwall shearers to shuttle cars, roof bolters, and haul trucks.

We supply low-voltage mining cables (up to 1 kV) and high-voltage trailing cables (3.3 kV, 6.6 kV, 11 kV) in configurations from 3 to 5 power cores, with optional pilot, earth monitoring, and control conductors. Constructions comply with AS/NZS 2802, BS 6708, CSA C22.2 No. 96, and IEC 60245-based equivalents.

Key Design Features

• Extra-fine-wire annealed copper power and earth conductors for maximum flexibility
• EPDM rubber insulation — outstanding dielectric performance in wet conditions
• Semiconductive rubber core screens and overall copper wire screens
• Robust neoprene outer sheath — oil, abrasion, and UV resistant
• Optional pilot conductors, earth monitoring cores, and fibre optic elements
• Temperature range ‑40°C to +90°C; LV to 11 kV
• Flame propagation resistance per IEC 60332

Available Voltage Ratings

Typical Applications

• Continuous miners and longwall shearers (underground coal)
• Shuttle cars, feeder breakers, and belt conveyors
• Roof bolters and raise boring machines
• Surface haul trucks and draglines (open-cast mining)
• Underground substations and transformer connections
• Tunnelling TBM power supply cables

Selection Guide

LV vs HV Mining Cable

For machinery at 480V or 1 kV, LV mining cable provides the necessary flexibility and earth fault protection at lower cost. For longer cable runs (over 100 m) or higher-power machines, 3.3 kV or 6.6 kV HV trailing cable reduces voltage drop and current loading significantly.
