6/10kV High Voltage Reeling Cable | Flexible Mining and Industrial Power Supply Cable

The RS-HVR series is a 6/10kV high voltage reeling cable for heavy industrial cranes, mobile excavators, and mining equipment. Its double-sheathed anti-torsion construction self-retracts flawlessly under intense winding tension, while the abrasion-resistant PUR jacket prevents insulation breakdown over millions of continuous reeling cycles. 

Key Benefits:

High-voltage safety rated at 6/10kV with extruded semi-conductive shielding layers.
Extreme tensile strength reinforced with aramid braid to support heavy reeling pull.
Creep-resistant PUR resists severe stone impacts, tearing, moisture, and oils.
Custom configurations built to your exact cross-section and dynamic drum requirements.

 

6/10kV High Voltage Reeling Cable | Flexible Mining and Industrial Power Supply Cable

Cable Construction

Our 6/10kV reeling cables feature a rugged multi-layer design to withstand harsh operational stress:

  • High-Flex Conductors: Class 5/6 tinned oxygen-free copper wires to prevent conductor metal fatigue.

  • HV Shielding System: Extruded inner/outer semi-conductive layers + tinned copper wire braid for electric field balance.

  • Integrated Grounding: Split protective earth cores + pilot cores for continuous monitoring and safety shutdown.

  • Anti-Torsion Mesh: High-tensile Kevlar® aramid braid embedded between sheaths to prevent corkscrewing.

  • Outer Sheath: Heavy-duty, flame-retardant Polyurethane (PUR) resistant to water immersion, tearing, and UV.

FAQ

Q1: Does this cable experience partial discharge under constant high-speed winding?

A1: No. We utilize triple-extrusion technology to apply the conductor shielding, high-grade insulation, and insulation shielding seamlessly in a single pass. This eliminates air gaps and voids inside the core, guaranteeing zero partial discharge and absolute electrical stability at 6/10kV.

Q2: How does the cable jacket handle scraping against rocks and iron structures?

A2: The outer jacket is formulated from premium, high-density thermoplastic polyurethane (PUR). It features excellent tear propagation resistance and high tensile strength, allowing it to withstand severe abrasion, sharp stone impacts, and scraping without exposing the core elements.

Q3: Can fiber optic elements be integrated for crane data transmission?

A3: Yes. We offer hybrid variations that house 6, 12, or 24 single-mode or multi-mode fiber optic elements within the core assembly. The optical fibers are protected inside a loose tube buffer to ensure uninterrupted network telemetry alongside high-voltage power.
