What Makes Feichun AS/NZS 1802 Type 241 Mining Cable Different from Other Mining Cables?

AS/NZS 1802 Type 241 mining cable is a semiconductive elastomer screened flexible power cable designed for medium-voltage mining applications ranging from 1.1 kV up to 11 kV. Unlike metal-screened designs, Type 241 uses a semiconductive screen, offering a balance between electrical performance, flexibility, and mechanical robustness—a combination that is particularly valuable in underground and mobile mining environments.

Feichun’s Type 241 cable is widely used for:

  • Continuous miners

  • Feeder cables to pumps

  • Monorails supplying Distribution Control Boxes (DCBs)

  • Longwall mining systems

Its compliance with AS/NZS 1802, proven flame-retardant behaviour, and excellent resistance to mechanical, chemical, and environmental stresses make it a trusted solution in Australian and South African mining operations.

What Applications Is Type 241 Mining Cable Designed For?

Type 241 is classified as a general-purpose medium-voltage mining cable, but its design clearly targets dynamic, mechanically demanding applications.

Typical Use Scenarios

  • Continuous miners requiring flexible, screened power supply

  • Underground pump feeders in wet or chemically aggressive conditions

  • Monorail systems supplying power to DCBs

  • Longwall face equipment, where repeated bending and movement occur

Because the cable uses a semiconductive elastomer screen instead of a metallic screen, it is typically more flexible and easier to handle during installation and relocation.

How Is Type 241 Installed in Mining Environments?

What Installation Conditions Are Suitable?

Feichun Type 241 cables are suitable for:

  • Installation in free air

  • Duct installations

  • Mobile mining equipment

  • Fixed or semi-fixed machines and feeders

Installation Best Practices

  • Maintain adequate minimum bending radius, especially for larger cross-sections

  • Avoid sharp edges and unprotected steel supports

  • Ensure correct earthing and pilot core termination

  • Regularly inspect sheath integrity in high-impact zones

Proper installation significantly extends cable life and reduces unplanned downtime.


How Is Type 241 Used in Real South African Mining Projects?

Case Study: Platinum Mine in Limpopo Province

In a deep-level platinum mine in Limpopo, Type 241.6 (6.6 kV) cables were selected to power:

  • Underground pump stations

  • Monorail-mounted DCBs

  • Mobile auxiliary equipment

Key reasons for selection:

  • Superior flexibility in confined tunnels

  • Reliable operation under wet and abrasive conditions

  • Compliance with site safety standards aligned with AS/NZS and local mining regulations

After installation, the mine reported reduced cable failures and lower maintenance costs compared to older metal-screened alternatives.
