AS/NZS 1802 Type 245F and 241F Electro-Optic Mining Cable

Modern automated longwall faces, remote-controlled continuous miners and high-capacity rail-mounted stacker-reclaimers require simultaneous medium-voltage power delivery and interference-free optical data transmission inside a single trailing cable envelope. AS/NZS 1802 Type 245F and Type 241F electro-optic mining cables integrate three individually screened R-EP-90 EPR power cores, earth-continuity pilot conductors and a dedicated crush-resistant optical fibre assembly in one flexible round profile.

Understanding the structural distinction between Type 241F and Type 245F is essential when matching Australian and international underground coal mine protection philosophies. In Type 241F, each of the three semi-conducting screened power cores carries a helically braided tinned-copper and polyester composite earth screen that remains in mutual contact around the central elastomeric cradle. In Type 245F, each power-core composite screen is further enclosed within its own individual elastomeric barrier jacket, physically isolating the three phase earth screens to restrict inter-phase fault propagation in high-energy longwall face circuits.

The integrated fibre-optic sub-unit replaces one outer interstice filler or occupies a protected cradle channel, utilizing loose-tube or tight-buffered single-mode OS2 (ITU-T G.652.D) or multimode OM3/OM4 fibres reinforced with non-metallic aramid yarns and an elastomeric jacket. An open-weave polyamide anti-torsion braid embedded between the inner and outer heavy-duty HD-85-PCP polychloroprene sheaths prevents corkscrewing and axial fibre strain inside Bretby cable handler chains.

AS/NZS 1802 Type 245F and 241F Applications

Specify AS/NZS 1802 Type 245F and Type 241F electro-optic cables where mobile underground or surface mining machines demand combined power, earth-screen protection, pilot interlocking and high-speed optical telemetry.

• Underground coal longwall shearers and armored face conveyors (AFC) operating inside Bretby automatic cable handler chains with real-time optical horizon-control and automation telemetry.
• Continuous miners, roadheaders and mobile bolting rigs requiring 1.1/1.1 kV or 1.9/3.3 kV trailing power paired with immune-to-EMI fiber optic video, lidar and gas-monitoring links.
• Open-cut and port bulk-handling stacker-reclaimers, ship loaders and mobile crushing stations where reeling or trailing cables carry both motor power and PLC fieldbus fiber.
• Direct engineering upgrades from standard non-optical Type 241 or Type 245 cables when retrofitting legacy mining machinery with fiber-optic diagnostics.

AS/NZS 1802 Type 245F and 241F Model Comparison and Selection Boundary

Verify coupler gland entry bore before substituting Type 245F for Type 241F, as the individual elastomeric barrier sheath over each phase core increases nominal outside diameter by 1.6 mm to 3.2 mm.

AS/NZS 1802 Type 245F and 241F Frequently Asked Questions

What is the structural difference between AS/NZS 1802 Type 241F and Type 245F electro-optic cables?

In Type 241F, the helically braided tinned-copper/polyester composite earth screens over the three R-EP-90 EPR power cores remain in direct mutual contact around the semi-conducting central cradle. In Type 245F, each power-core composite screen is enclosed within its own extruded elastomeric barrier jacket, isolating the three phase screens to limit inter-phase fault energy on longwall faces.

Which optical fibre grades and counts can be specified in Type 245F and Type 241F?

Both Type 245F and Type 241F can be built with 6, 12 or 24 optical fibres in single-mode OS2 (ITU-T G.652.D, 9/125 um) or laser-optimized multimode OM3 and OM4 (ISO/IEC 11801, 50/125 um) protected inside an aramid-reinforced elastomeric sub-unit.

Does the individual phase barrier on Type 245F affect mining plug and gland selection?

Yes. Because each screened power core in Type 245F carries an individual elastomeric barrier jacket, the nominal overall cable diameter is 1.6 mm to 3.2 mm larger than an equivalent Type 241F size; always confirm coupler gland bore dimensions before ordering.

What are the minimum order quantity and delivery lead time for Type 245F and Type 241F?

TEBAOFLEX manufactures custom continuous lengths of AS/NZS 1802 Type 245F and Type 241F from a 50 m minimum order quantity (MOQ) with a lead time of 7 to 45 working days, including routine high-voltage, partial-discharge and OTDR optical test reports.

Current-carrying capacities are referenced to 30 °C ambient air temperature and 90 °C maximum conductor operating temperature in free air away from direct solar radiation; apply AS/NZS 3008.1.1 derating factors where cables are layered in Bretby handlers, troughs or reels.

Type 245F nominal outside diameters are 1.6 mm to 3.2 mm larger than Type 241F of the same conductor cross-section due to the individual elastomeric barrier sheaths extruded over each composite phase screen; verify mining coupler gland entries before ordering.

Specify the exact fibre type (OS2 9/125 um, OM3 50/125 um or OM4 50/125 um), fibre count (6, 12 or 24 fibres) and whether one or two copper pilot cores are required alongside the optical unit.
