Type 240 Underground Coal Mine Cable 1.1kV to 11kV
Type 240 Underground Coal Mine Cable 1.1kV to 11kV is a TEBAOFLEX cable for the application and operating conditions identified in the original product record. The supplied cross-section and cutaway illustrate three screened phase conductors together with three smaller pilot conductors. The visible braid belongs to the phase-core screen; it is not a substitute for verifying the intended earthing and bonding arrangement at the equipment termination. The following selection table reproduces the supplied nominal dimensions. Send the exact size, length, installation duty and documentation requirements for a technical quotation.

Manual review: the supplied 240.1 row for 35mm² shows 53.6mm nominal diameter, while the following 50mm² row shows 48.4mm. This may be a source-table anomaly; confirm the 35mm² outer diameter before production or replacement ordering. The stated application is general use in underground coal mines, excluding shuttle cars. The supplied reference also identifies use in underground mine environments where explosive gases and dust may accumulate. This application statement does not by itself confirm hazardous-area approval, so the mine’s electrical and safety requirements must be checked for every installation. Type 240 underground coal mine cable is a screened 3+3 core mine power cable family for general underground coal-mine service, excluding shuttle-car duty. The source record places this product in mining & tunneling cables. Before ordering, confirm the exact product variant, conductor or core arrangement, system rating, route conditions, equipment connection and required documentation against the project specification.
Type 240 Underground Coal Mine Cable 1.1kV to 11kV construction
Cable Construction
The supplied cross-section and cutaway illustrate three screened phase conductors together with three smaller pilot conductors. The visible braid belongs to the phase-core screen; it is not a substitute for verifying the intended earthing and bonding arrangement at the equipment termination.
- Conductor: flexible stranded tinned copper phase conductors.
- Separator and insulation: semiconductive layers where specified and R-EP-90 insulation.
- Phase-core screen: tinned copper/nylon braid over each phase core.
- Pilot system: three interstitial pilot cores among the phase cores.
- Lay-up and sheath: semiconductive cradle and heavy-duty elastomeric outer sheath.
Type 240 Underground Coal Mine Cable 1.1kV to 11kV applications
Applications
The stated application is general use in underground coal mines, excluding shuttle cars. The supplied reference also identifies use in underground mine environments where explosive gases and dust may accumulate. This application statement does not by itself confirm hazardous-area approval, so the mine’s electrical and safety requirements must be checked for every installation.
Selection Notes for Buyers
- Select Type 240.1, 240.3, 240.6 or 240.11 from the system voltage, then select conductor area from load current and permissible voltage drop.
- Check the nominal outer diameter and mass against cable-route space, supports and handling equipment.
- Confirm the three pilot-core purpose and its termination at both ends before substituting another cable family.
- Do not treat the general underground-mine application as proof of Ex or hazardous-area certification; request the project’s required approval and documentation separately.
- For a replacement, provide the complete sheath marking, voltage type, conductor area, pilot details and a photo of the termination.
Selection checks
Confirm the equipment interface, installation method, route length, movement or flexing duty, environmental exposure, conductor or core requirements and project documentation before final selection.
