AS/NZS 2802 Type 412 1.1/1.1KV Pliable Armoured Feeder Cable for Sand Mining Applications

When sand mining operations demand continuous power delivery under high mechanical stress, selecting the right mining feeder cable becomes critical. Among the most reliable solutions is the Feichun AS/NZS 2802 Type 412 1.1/1.1kV Pliable Armoured Feeder Cable, specifically engineered for environments where abrasion, impact, and downtime risks are high.

What Is AS/NZS 2802 Type 412 and How Does It Differ from Other Mining Cables?

AS/NZS 2802 Type 412 is a low-voltage (1.1/1.1kV) pliable armoured mining feeder cable designed for mobile and semi-fixed power distribution in mining environments.

Unlike rigid armoured cables, Type 412 combines mechanical protection with flexibility, making it ideal for sand mining where cables are frequently exposed to:

• Moving machinery

• Shifting ground and slurry

• Mechanical impact from loaders and conveyors

• Frequent repositioning

Its defining feature is pliable galvanised steel wire armour, which reduces cable damage while maintaining flexibility.

How Is the Feichun AS/NZS 2802 Type 412 Cable Constructed?

The cable’s layered construction balances electrical performance, flexibility, and mechanical protection.

What Type of Conductors Are Used in Type 412 Mining Cable?

• 3 × Flexible stranded tinned annealed copper conductors

• Excellent conductivity and corrosion resistance

• High strand count improves flexibility under repeated movement

Why Is EPR Insulation Used in Type 412 Cables?

• EPR (Ethylene Propylene Rubber) insulation offers:

  • High dielectric strength

  • Resistance to moisture and chemicals

  • Stability under heat and mechanical stress

What Is the Role of the Insulation Screen?

• Semiconductive elastomer screen

• Ensures uniform electric field distribution

• Reduces partial discharge risk

How Is Earthing Achieved in Type 412 Mining Cables?

• 3 × interstitial earth conductors

• Flexible stranded tinned copper, EPR covered

• Green/yellow identification for safety compliance

• Provides reliable fault current paths

Why Is Pliable Armour Important in Sand Mining?

• Galvanised low-carbon steel wire armour

• Protects against crushing, abrasion, and impact

• Maintains flexibility unlike rigid steel tape armour

• Reduces downtime caused by accidental cable damage

What Sheathing Materials Are Used?

• Inner sheath: PCP (Polychloroprene)

• Outer sheath: Heavy-duty PCP

• Optional upgrades: CPE or CSP for enhanced oil and chemical resistance

Where Is AS/NZS 2802 Type 412 Commonly Used in Sand Mining?

Why Is Type 412 Ideal for Sand Mining Feeder Applications?

Sand mining environments expose cables to:

• Abrasive sand particles

• Wet and muddy conditions

• Heavy mobile equipment

• Frequent mechanical contact

Type 412’s pliable armour and robust PCP sheath reduce sheath cuts and conductor damage, lowering maintenance costs.

Typical Applications Include:

• Power feeders for sand dredges

• Supply cables for wash plants

• Conveyor and screening equipment

• Mobile crushers and loaders

• Temporary power distribution in open-pit sand operations

How Does Type 412 Compare with Other AS/NZS Mining Cables?

Type 412 vs Type 210 Mining Cable

Conclusion: Type 412 is preferred where mechanical damage risk is high, while Type 210 suits lighter trailing duties.

What Installation Practices Improve Type 412 Cable Performance?

How Should Type 412 Be Installed in Sand Mining Sites?

• Avoid excessive tension during pulling

• Maintain recommended minimum bending radius

• Provide proper cable support at entry points

• Use protective ramps at vehicle crossing zones

Can Type 412 Be Buried Directly in Sand?

Yes, but it is recommended to:

• Use sand bedding free of sharp stones

• Avoid direct burial in high-traffic areas without protection

• Inspect regularly for sheath wear

Frequently Asked Questions (FAQ)

Is AS/NZS 2802 Type 412 suitable for continuous flexing?

It is designed for limited movement and repositioning, not constant reeling like trailing cables.

Can CPE or CSP sheaths be specified instead of PCP?

Yes. CPE/CSP options are recommended for oil-rich or chemically aggressive environments.

Does Type 412 meet mining safety earthing requirements?

Yes. The three interstitial earth conductors ensure effective grounding and fault protection.

Is Type 412 acceptable for export projects outside Australia?

Yes. It is widely accepted in South Africa, Southeast Asia, and African mining projects due to its robust design.
