What Makes AS/NZS 2802 Type 440 Different from Other Mining Cables?
AS/NZS Type 440 is classified as a Class 2 composite screened mining cable, designed for general mining use where long cable lengths, pilot circuit stability, and mechanical robustness are critical.
Unlike Type 409 or Type 441, Type 440 is often selected when:
Long trailing distances risk pilot resistance drift
High mechanical impact and abrasion are expected
Frequent reeling or trailing movement is unavoidable
Key Design Philosophy
Composite earth screening for improved fault protection
Multiple pilot cores for monitoring and interlocking
Heavy-duty sheath for harsh, mobile mining environments
How Do Type 440 Variants Compare (1.1 kV vs 3.3 kV vs 6.6–22 kV)?
Type 440 Variant Comparison Table
Type | Typical Voltage | Insulation Thickness | Typical Application |
|---|---|---|---|
Type 440.1 | 1.1 kV | ~1.5–3.0 mm | Low-voltage mobile equipment |
Type 440.3 | 3.3 kV | ~3.0 mm | Medium-duty open-cut mining |
Type 440.6 | 6.6 kV | ~5.0 mm | High-power shovels & conveyors |
Type 440.11 | 11 kV | ~7.6 mm | Long-distance trailing |
Type 440.22 | 22 kV | ~10.5 mm | High-capacity mining systems |
Where Is AS/NZS Type 440 Mining Cable Commonly Used?
What Mining Equipment Uses Type 440 Cables?
Type 440 is widely used for:
Electric rope shovels
Draglines
Mobile crushers
High-power conveyors
Bucket wheel reclaimers
It is suitable for:
Trailing applications

Free-air installation
What Installation Conditions Should Be Considered for Type 440?
Best-Practice Installation Advice
Avoid tight bending radii during deployment
Use cable rollers on long runs
Ensure proper earthing continuity checks
Select Kevlar-reinforced sheath for frequent reeling
Match pilot resistance requirements to protection systems
Correct installation significantly extends service life and improves safety compliance.
How Does Type 440 Compare with Type 409 and Type 441?
Feature | Type 409 | Type 440 | Type 441 |
|---|---|---|---|
Pilot Stability (long runs) | Moderate | Excellent | Good |
Mechanical Strength | Good | Very High | High |
Reeling Suitability | Limited | Yes | Yes |
Voltage Range | Limited | 1.1–22 kV | Medium |
Type 440 is often chosen when Type 409 or Type 441 cannot meet pilot resistance or mechanical durability requirements.
Frequently Asked Questions About AS/NZS Type 440 Mining Cable
Is Type 440 suitable for both trailing and reeling applications?
Yes. It is specifically designed for trailing and most reeling applications, especially where mechanical stress is high.
Can Type 440 be used in harsh weather conditions?
Absolutely. It is resistant to UV, rain, temporary water immersion, and extreme temperature variations.
Why choose EPR insulation instead of XLPE?
EPR offers superior flexibility, better thermal ageing, and improved resistance to cracking in mobile mining environments.
Does Type 440 comply with flame retardancy requirements?
Yes. The cable is fire retardant and compliant with AS/NZS 2802 flame behaviour requirements.
