AS/NZS 1802 Type 240 1.1-11 kV
AS/NZS 1802 Type 240 1.1-11 kV
Cable description:
Composite screened cable for general use to AS/NZS 1802.
Application:
1.1/1.1 kV to 11/11 kV cable used extensively for feeder connection between transformer and gate-end box or similar, continuous miner cable or feeder cables to pumps. Having three pilots, the cable can be used in long runs, without compromising pilot control protection system resistance limitations. For applications requiring high degrees of flexibility, Type 241 cables would be more appropriate.

What Makes AS/NZS 1802 Type 240 Different from Other Mining Cables?
Unlike standard flexible mining cables, Type 240 is a composite-screened underground cable designed for long feeder runs and pilot-controlled systems.
Key distinguishing features include:
Voltage range from 1.1 kV up to 11 kV
Three power cores + three pilot conductors
Composite earth screen for enhanced fault protection
Heavy-duty PCP outer sheath for mechanical and chemical resistance
If high flexibility is the primary requirement, AS/NZS Type 241 is often preferred. However, when electrical integrity, pilot monitoring, and long-distance feeder performance matter most, Type 240 becomes the go-to solution.
What Are the Key Electrical and Physical Specifications?
What Voltage Ratings Are Available?
Feichun Type 240 covers a broad voltage range:
1.1/1.1 kV
3.3 kV
6.6 kV
11 kV
This makes it suitable for both low-voltage and medium-voltage underground distribution systems.
How Do Electrical Parameters Affect Performance?
Key electrical characteristics include:
Low AC resistance at 90 °C, reducing losses
Stable reactance at 50 Hz, supporting long feeder runs
Controlled capacitance to earth, minimizing charging currents at higher voltages
For example, a 240 mm², 11 kV Type 240 cable offers:
AC resistance ≈ 0.106 Ω/km
Voltage drop ≈ 0.261 mV/A·m
Capacitance ≈ 0.309 μF/phase/km
These values ensure efficient power delivery with minimal voltage drop, even over extended distances.
Where Is AS/NZS Type 240 Commonly Used in Underground Mines?
What Are the Typical Applications?
Feichun Type 240 mining cables are widely used for:
Transformer to gate-end box feeders
Continuous miner supply cables
Pump stations in underground roadways
Fixed and semi-mobile mining machinery
The cable is suitable for installation:
In free air
In ducts
On mobile equipment
On fixed machines
How Does Type 240 Perform in Harsh Mining Conditions?
Type 240 is engineered to withstand:
Heavy mechanical impact
Frequent chemical exposure
Temporary water immersion
Direct solar radiation (surface transitions)
Its HD-85 PCP sheath provides excellent abrasion resistance, while optional sheath reinforcement can be specified for extreme conditions.
How Does Type 240 Compare with Other AS/NZS Mining Cables?
Type 240 vs Type 241: Which Should You Choose?
Feature | Type 240 | Type 241 |
|---|---|---|
Voltage range | 1.1–11 kV | 1.1–11 kV |
Flexibility | Flexible | Extra flexible |
Typical use | Feeders & fixed runs | Highly mobile equipment |
Pilot system | Three pilots | Three pilots |
Best for | Long runs, stability | Frequent movement |
Recommendation:
Choose Type 240 for long underground feeders and Type 241 where constant movement is required.
What Should Be Considered During Installation?
What Are the Best Installation Practices?
To maximize service life:
Maintain minimum bending radius during pulling
Avoid twisting that may stress composite screens
Use proper cleating to prevent sheath abrasion
Ensure correct earthing of composite screen
Verify pilot continuity before energization
For duct installations, ensure:
Smooth duct interiors
Adequate pulling lubricant
Controlled pulling tension
Frequently Asked Questions (FAQ)
Can Type 240 Be Used for Mobile Mining Equipment?
Yes, but only for limited movement. For constant trailing applications, Type 241 or reeling cables are better suited.
Is Type 240 Flame Retardant?
Yes. The cable is fire retardant and complies with AS/NZS 1802 flame behavior requirements, enhancing underground safety.
What Temperature Range Can Type 240 Handle?
Maximum operating temperature: +90 °C
Minimum operating temperature: −25 °C
This makes it suitable for both deep underground and surface transition areas.
Does Type 240 Support Long Pilot Circuits?
Yes. The three-pilot design enables long feeder runs without exceeding pilot system resistance limits, a major advantage in large mines.
