What Is the Feichun AS/NZS Type 451 Mining Cable?
The Feichun AS/NZS Type 451 is a Class 1 composite screened cable designed for general mining use. It is a reeling and trailing cable suitable for slow-moving equipment, such as draglines, shovels, excavators, wharf cranes, and materials handling machinery.
Compared to its close relative, the Type 450 cable, the Type 451 has a reduced pilot size, which optimizes flexibility while maintaining safety and performance in heavy-duty mining operations.
Key highlights include:
Voltage rating: 3.3/3.3 kV to 33/33 kV
Flexibility: Suitable for trailing and slow reeling
Temperature range: -25°C to +90°C
Fire behavior: Fire-retardant and suitable for harsh mining conditions
Resistance: Excellent chemical resistance, heavy mechanical impact tolerance, temporary water immersion, and solar/weather exposure suitability
Where Can the Type 451 Mining Cable Be Applied?
The Type 451 is versatile and can be used in multiple mining scenarios:
Which Mining Equipment Is Compatible?
Draglines and Excavators: Ensures reliable power transmission even under continuous motion
Shovels: Maintains safety and performance in heavy-duty material handling
Wharf Cranes: Durable enough for coastal and port-based mining operations
Materials Handling Equipment: Suitable for slow reeling and trailing applications
Can It Withstand Harsh Conditions?
Yes, the Type 451 can survive chemical exposure, mechanical impacts, water immersion, and extreme temperature variations, making it suitable for South African open-cut and underground mines.
Case Study: In the South African platinum belt, Type 451 cables have been deployed on dragline operations where other cables failed under constant mechanical stress. The Type 451’s Kevlar® reinforcement significantly reduced cable replacements, improving operational uptime by 15%.
How Does Type 451 Compare to Other Mining Cables?
Comparison Table: Type 450 vs Type 451
Feature | Type 450 | Type 451 |
|---|---|---|
Pilot Size | Standard | Reduced for flexibility |
Voltage Range | 3.3–33 kV | 3.3–33 kV |
Mechanical Reinforcement | XHD sheath | XHD-85-PCP + Kevlar® braid |
Best For | Slow reeling | Slow reeling + trailing, mobile equipment |
Typical Applications | Draglines, shovels | Draglines, shovels, excavators, cranes |
Summary: Type 451 offers the same power capabilities as Type 450 but with enhanced flexibility and reduced pilot size, making it ideal for mobile or trailing applications.
How Should the Type 451 Cable Be Installed?
Proper installation ensures maximum cable longevity and safety.
What Are Installation Recommendations?
For free-air installation: Ensure minimum bending radius is maintained according to voltage and conductor size
For mobile equipment: Avoid sharp bends; maintain consistent reeling and trailing tension
Environmental precautions: Keep the cable away from corrosive chemicals, extreme heat sources, and mechanical pinch points
Routine inspections: Check sheath integrity, pilot continuity, and screen bonding before full deployment
Pro Tip: Using cable rollers and protective sheaths in high-wear zones significantly increases service life.
Frequently Asked Questions (FAQ) About Type 451 Mining Cable
Can Type 451 Cables Be Used in Underground Mines?
Yes. While originally designed for open-cut mines, the Type 451’s fire-retardant and flexible design make it suitable for underground slow-reeling operations with moderate mechanical stress.
What Is the Maximum Operating Temperature?
The Type 451 operates safely up to +90°C. It can handle extreme South African summer heat, ensuring consistent power transmission.
How Resistant Is It to Mechanical Impact?
The Kevlar® reinforced XHD sheath provides heavy mechanical impact resistance. It can endure dragging over rough surfaces and minor collisions without damage.
What Are the Differences Between Voltage Variants?
Higher voltage variants (11–33 kV) have:
Thicker insulation for dielectric strength
Heavier sheaths for mechanical protection
Slightly higher mass per 100 m
These design adjustments maintain electrical performance and safety at higher voltages.
How Often Should the Cable Be Inspected?
Regular inspections are recommended every 3–6 months, focusing on:
Pilot core continuity
Sheath abrasion or cuts
Electrical performance and voltage drop
Installation Tips for Maximum Longevity
Avoid sharp bends below recommended bending radius
Use proper supports to minimize cable drag on sharp edges
Keep the cable clean and free from chemical spills
Test pilot continuity regularly for operational safety
Document cable deployment to anticipate wear patterns
Why South African Mining Companies Choose Type 451
South African mining operations often demand long-distance, high-voltage power for mobile equipment. The Type 451 is favored because:
Durable in harsh environments: Chemical, mechanical, and thermal resistance
