What Is the Feichun AS/NZS 2802 Type 441 Mining Cable?

The Type 441 is a Class 2, semiconductive screened cable designed for general use in trailing and reeling applications, suitable for supplying power to mobile equipment in open-cut mines. Its approval under AS/NZS 2802 ensures compliance with Australian and New Zealand mining safety standards. Key highlights include:

  • Voltage rating: 1.1 kV

  • Fire behaviour: Fire-retardant

  • Temperature range: -25 °C to +90 °C

  • Flexibility: Highly flexible, suitable for mobile and trailing applications

  • Resistance: Excellent chemical resistance, heavy mechanical impact tolerance, temporary immersion in water, and direct solar exposure

The Type 441 cable is specifically engineered to meet the harsh conditions of open-cut mining, where exposure to chemicals, mechanical abrasion, and extreme weather is common.

How Does Type 441 Compare to Other Mining Cables?

For practical decision-making, mining engineers often compare Type 441 with Type 440 and Type 409, two other widely used Feichun AS/NZS 2802 mining cables.

Observation: Type 441 is more flexible and mechanically robust than Type 440 and Type 409, making it ideal for mobile open-cut mining operations.

Where Is Type 441 Commonly Used in Mining?

The Type 441 cable is highly versatile and deployed in trailing and reeling systems, mobile equipment, and general-purpose electrical supply in open-cut mines. Specific use cases in South Africa include:

  • Platinum mines in Rustenburg: Power supply for mobile loaders and excavators

  • Gold mines in Witwatersrand: Reeling cables for haul trucks and temporary lighting systems

  • Coal mines in Mpumalanga: Mobile pump and conveyor systems

These applications benefit from the cable’s flexibility, chemical resistance, and fire-retardant properties, ensuring operational continuity even in harsh environments.


What Are the Installation Recommendations for Type 441?

Proper installation extends the life and performance of the cable. Key recommendations include:

  1. Free Air Installation: Ensure adequate airflow to prevent heat accumulation.

  2. Mobile Equipment: Use trailing arrangements that avoid sharp bends or excessive tension.

  3. Protection: If mechanical impact is extreme, consider Kevlar® braid reinforcement.

  4. Chemical Exposure: Inspect periodically if exposed to acids, oils, or cleaning agents.

  5. Temperature Range: Avoid sustained exposure above +90 °C or below -25 °C.

Adhering to these practices minimizes insulation degradation, electrical faults, and maintenance costs.

Installation Tips: How to Maximize Performance?

  • Avoid sharp bends: Maintain minimum bending radius to prevent insulation stress.

  • Use cable rollers: Especially for heavy trailing applications to reduce wear.

  • Secure connections: Use proper lugs and terminations for tinned copper cores.

  • Monitor temperature and voltage: Prevent overheating in high-current applications.


Why Choose Feichun AS/NZS 2802 Type 441 for Open-Cut Mines?

The Type 441 mining cable stands out due to:

  • Compliance: Fully meets AS/NZS 2802 standards

  • Mechanical Strength: Heavy-duty impact resistance

  • Flexibility: Suitable for trailing and mobile operations

  • Durability: Resistant to chemicals, water, and UV exposure

  • Fire Safety: Fire-retardant for enhanced workplace safety

Choosing Type 441 minimizes operational risks while providing a reliable power supply in challenging mining environments.

Where to Buy and How to Specify

For mining engineers and procurement managers looking to upgrade or replace their open-cut mine cables, consider consulting Feichun or authorized distributors to specify the correct Type 441 cable size and optional reinforcement. Ensure you:

  • Match nominal area to equipment current demand

  • Decide on Kevlar® reinforcement based on mechanical exposure

  • Follow installation and maintenance guidelines

Investing in the right cable improves efficiency, safety, and equipment uptime in the long term.
