What Is the Feichun PUR HF Without Anti-Twisting Protection Cable?
The Feichun PUR HF 0.6/1 kV power cable is a halogen-free, flame-retardant, flexible PUR-sheathed cable designed for mobile equipment exposed to high mechanical stress, particularly in mining and tunnel construction.
Unlike anti-twisting reeling cables, this design does not include torsion protection, which means it is intended for applications where the cable deflects in one plane only, such as linear travel or guided movements.
Key positioning:
Voltage class: 0.6/1 kV
Movement type: One-plane deflection
Maximum travel speed: 60 m/min
Safety focus: Halogen-free & flame-retardant
Which Applications Are Best Suited for This Cable?
Where Is This Cable Most Commonly Used?
Underground mining power supply
Tunnel construction equipment
LHDs and shuttle cars
Rail-guided mobile systems
Mining substations with moving feeders
Where Should It NOT Be Used?
Applications with continuous torsion
High-speed reeling systems exceeding 60 m/min
Crane systems requiring anti-twisting cores
How Does This Cable Compare to Other Mobile Mining Cables?
PUR HF Without Anti-Twisting vs Anti-Twisting PUR Cable
Feature | PUR HF (No Anti-Twist) | PUR Anti-Twisting |
|---|---|---|
Torsion resistance | ❌ No | ✅ Yes |
Cost | Lower | Higher |
Diameter | Smaller | Larger |
Ideal movement | One-plane | Multi-directional |
PUR HF vs Rubber (EPR/PCP) Cables
Aspect | PUR HF | Rubber |
|---|---|---|
Abrasion resistance | Excellent | Moderate |
Oil & chemical resistance | High | Medium |
Halogen-free | Yes | Often No |
Service life | Longer | Shorter |
What Cable Sizes and Electrical Ratings Are Available?
The Feichun PUR HF series covers 10 mm² to 240 mm², with or without control cores.
Example highlights:
Construction | Current Capacity |
|---|---|
4G16 | 99 A |
3×70+3G16 | 250 A |
3×150+3G25 | 404 A |
3×240+3G50 | 540 A |
This range supports small auxiliary machines to high-power mobile mining units.
How Should the Cable Be Installed for Maximum Service Life?
Installation Best Practices
Ensure guided cable routing to avoid twisting
Respect minimum bending radius
Avoid sharp edges and pinch points
Use cable rollers in long tunnel runs
Secure strain relief at connection points
Common Installation Mistakes
Using in torsional reeling systems
Exceeding maximum travel speed
Ignoring temperature limits
How Is This Cable Used in South African Mining Projects?
Case Study: Platinum Mine Tunnel Expansion – Limpopo
During a platinum mine tunnel extension project in Limpopo, Feichun PUR HF 1 kV cables were selected for:
Mobile drilling platforms
Tunnel ventilation booster units
Why this cable was chosen:
Halogen-free design met mine safety policy
PUR sheath resisted abrasive rock surfaces
One-plane cable guidance matched tunnel layout
After 18 months of operation, inspections showed:
No sheath cracking
Stable insulation resistance
Reduced maintenance compared to rubber cables
Frequently Asked Questions (FAQ)
Is this cable suitable for reeling drums?
Yes, only for linear reeling systems without torsional stress and within 60 m/min.
Can control cores be integrated?
