Type 241.1 Mining Cable and Type 241 Voltage Family
Type 241.1 cable is the 1.1/1.1 kV member of the AS/NZS 1802 Type 241 reeling and trailing cable family for underground coal-mine feeder and equipment circuits. This page also retains Type 241.3, 241.6 and 241.11 data so buyers can select the correct voltage grade without creating overlapping product pages.
The construction combines three screened flexible power cores, three interstitial earth conductors and a central pilot, assembled with semiconductive layers, braid reinforcement and a heavy-duty elastomeric sheath. Select the model by system voltage first, then check phase area, earth and pilot arrangement, termination design, route length and movement duty. Type 241.1 is not automatically suitable for every shuttle-car or high-speed reeling application.
Use the approved cable schedule and mine engineering requirements for final release.
- Type 241.1: 1.1/1.1 kV, 6 to 300 mm2 supplied phase-size range.
- Other grades: 3.3/3.3, 6.6/6.6 and 11/11 kV options are tabulated.
- RFQ inputs: equipment, voltage, length, movement, terminations, marking and test documents.

Construction
The Type 241 arrangement combines three semiconductive-screened power cores with three interstitial earth conductors and one central pilot. The layer sequence below reflects the supplied construction data; final materials and dimensions must be confirmed on the quotation and approved cable schedule.
| Layer or element | Supplied construction | Selection relevance |
|---|---|---|
| Power conductors | Flexible multi-stranded circular tinned copper, rope lay; supplied reference to AS/NZS 1125. | Confirm phase-conductor area from the required current and voltage-drop calculation. |
| Conductor separator / screen | Semiconductive layer over power conductors at 3.3/3.3 kV and above. | The termination system must match the screen construction of the selected voltage grade. |
| Power-core insulation | R-EP-90 elastomeric insulation. | Confirm the rated-voltage variant before selecting the size. |
| Insulation screen | Semiconductive layer over the power-core insulation. | Screen preparation and termination instructions must be agreed for the project. |
| Earth conductors | Three flexible interstitial earth conductors with semiconductive covering. | Confirm earth-conductor area and bonding arrangement with the mine electrical design. |
| Central pilot | One R-EP-90 insulated pilot core at the centre of the semiconductive cradle. | State the pilot function, conductor requirement and both-end termination. |
| Lay-up and bedding | Power cores and interstitial earth conductors laid around a semiconductive cradle, with semiconductive elastomeric bedding. | Maintains the specified core geometry and semiconductive assembly. |
| Reinforcement | Open-weave braid beneath the outer sheath. | Movement, pulling and handling duty still require separate confirmation. |
| Outer sheath | Heavy-duty elastomeric outer sheath. | Confirm compound, colour, marking and environmental performance required by the project. |
Applications
Type 241 is a general-use underground coal-mine power cable family. It is a suitable starting point when a feeder or equipment-supply circuit requires semiconductive-screened power cores, three earth conductors and a central pilot, subject to the selected voltage grade and mechanical duty.
Typical circuit roles
- Flexible feeder cable for continuous-miner power circuits.
- Pump feeder and general underground mine power-supply circuits.
- Power supply to monorail, distribution and longwall-related equipment where the required movement duty is verified.
- Replacement projects that match the Type 241 voltage, core configuration, earth system and pilot function.
Use boundaries to confirm
- Shuttle cars: Do not select Type 241 solely from the voltage; high-speed shuttle-car reeling requires a cable type and mechanical design verified for that duty.
- Repeated flexing or cable chains: Provide bend radius, drum or sheave diameter, travel speed, pulling load and cycle information.
- Wet, oily, abrasive or chemically exposed routes: State the actual exposure so the sheath compound and test requirements can be confirmed.
- Hazardous mine areas: A product description does not establish site approval; provide the required standard edition, certificate and inspection scope.

- A standard reference does not by itself prove certification, mine-site approval or suitability for a hazardous zone.
- Confirm the jurisdiction, standard edition, cable marking, certificate scope and acceptance procedure with the responsible project engineer.
- Do not assume flame, oil, water, UV, chemical or temperature performance unless it appears in the approved technical offer and supporting evidence.
