AS/NZS 1972 Type 1 1.1 kV Mining Feeder Cable
AS/NZS 1972 Type 1 1.1 kV Mining Feeder Cable
Cable description: PVC insulated and covered, screened cable.
Application:
Cable designed for the wiring of mobile equipment such as continuous miners, shuttle cars, road headers, personnel transports, etc. Type 1 cables require further mechanical protection when used in external (non-protected) installations. They are used for the interconnection of equipment, for example control boxes, motors, etc. Cables rated in excess of 20 amps are electrically symmetrical.

What Is the AS/NZS 1972 Type 1 1.1 kV Mine Feeder Cable Designed For?
The AS/NZS 1972 Type 1 Mine Feeder Cable is a PVC insulated, PVC sheathed, screened flexible mining cable specifically designed for power and control interconnection of mobile mining equipment.
It is widely used in:
Underground coal and hard-rock mines
Semi-protected mining environments
Machine-to-machine power and control wiring
Feichun Type 1 cables are intended for ducted or machine installations and require additional mechanical protection when installed in exposed or harsh external conditions.
Why Is the Feichun Type 1 Cable Commonly Used on Mobile Mining Equipment?
Mining machinery such as continuous miners, shuttle cars, roadheaders, and personnel transport vehicles requires cables that are:
Flexible
Electrically stable
Resistant to oils, chemicals, and moisture splashes
The Type 1 design provides:
Reliable screening for electrical symmetry and interference control
Excellent chemical and environmental resistance
Lightweight construction compared with heavy-duty trailing cables
This makes it ideal for interconnection between motors, control boxes, and auxiliary systems.
Does the Cable Offer Fire Resistance?
No.
AS/NZS 1972 Type 1 cables have no dedicated fire performance rating, meaning:
They are not flame-retardant or fire-resistant
They should not be used in fire-critical escape routes
For fire-rated requirements, higher-category mining cables should be selected.
How Does Type 1 Compare with Other Mining Cable Types?
Type 1 vs Heavy-Duty Trailing Cables
Feature | Type 1 | Trailing Cable |
|---|---|---|
Flexibility | High | High |
Mechanical protection | Light | Very heavy |
Installation | Duct/machine | Dragged on floor |
Fire performance | None | Often flame-retardant |
Cost | Lower | Higher |
Type 1 vs Type 2 or Type 3 Mining Cables
Aspect | Type 1 | Higher Types |
|---|---|---|
Mechanical resistance | Light | Medium–Heavy |
Fire rating | None | Often required |
Installation environment | Semi-protected | Harsh/exposed |
Where Are Feichun Type 1 Cables Used in South African Mines?
South African Case Study: Underground Platinum Mine (North West Province)
A South African platinum operation upgraded its machine interconnection wiring for shuttle cars and conveyor control boxes.
Why Type 1 Was Selected:
Installed in steel conduits and machine housings
Required excellent EMI control for PLC signals
Needed flexibility for vibration-prone equipment
Outcome:
Reduced electrical interference faults
Lower installation cost compared with heavy-duty alternatives
Compliance with AS/NZS 1972 and mine safety requirements
What Are the Recommended Installation Conditions?
Where Should Type 1 Cables Be Installed?
✔ In ducts
✔ Inside machinery
✔ Within protective conduits
❌ Not recommended for:
Direct burial
Dragging on mine floors
Exposed mechanical abuse
What Installation Tips Improve Service Life?
Always use additional mechanical protection in exposed areas
Maintain proper bending radius
Ensure screen termination is correctly grounded
Avoid sharp edges and unsupported spans
Frequently Asked Questions (FAQ)
Is AS/NZS 1972 Type 1 suitable for external mining installations?
Only if additional mechanical protection is provided. It is not designed for unprotected external use.
Can Type 1 cables be used for control and power together?
Yes. Multi-core and screened designs make them ideal for combined power and control circuits.
Are Type 1 cables symmetrical?
Cables rated above 20 A are electrically symmetrical, improving balanced three-phase performance.
Does the cable resist chemicals and moisture?
Yes. It offers very good resistance to chemicals, water splashes, and weather exposure.
Is this cable compliant with mining standards?
Yes. It is fully compliant with AS/NZS 1972 requirements.
What Should Buyers Consider Before Selecting a Type 1 Mine Feeder Cable?
Ask the following:
Is the installation protected or exposed?
Is fire performance required?
Do I need individual or collective screening?
What current and voltage margins are needed?
