Type 241.1 Trailing Cable: Reeling and Trailing Cable for Underground Coal Mining

What is Type 241.1 trailing cable?

Type 241.1 is a reeling and trailing cable purpose-built for underground coal mining, where a cable is repeatedly flexed, dragged, and crushed as mining equipment moves. HELU Australia's range uses Class 5 tinned and annealed copper conductors with flexible EPR insulation and a heavy-duty HD-85-PCP outer sheath, manufactured to AS/NZS 1802:2003 and AS/NZS 1125:2001, with a crush-resistant central cradle construction built specifically to survive the mechanical demands of reeling drums and trailing behind mobile mining machinery.

What we have to offer—At a glance

  • Built for underground coal mining: Manufactured to AS/NZS 1802:2003, the Australian standard specific to underground coal mining cable.
  • Crush-resistant central cradle construction: Reinforced construction to withstand the repeated crushing and flexing mining equipment puts a trailing cable through.
  • Flexible EPR insulation: Ethylene propylene rubber insulation stays flexible under constant reeling and dragging.
  • Heavy-duty HD-85-PCP outer sheath: A reinforced, radial-strengthened sheath that's oil-resistant and flame retardant.
  • Class 5 tinned copper conductors: Fine stranding for flexibility, with tinning for corrosion resistance in wet underground conditions.
  • Wide operating temperature range: Rated from -25°C to +90°C, with flexing and fixed minimum bend radii specified for safe installation and use.

Applications for Type 241.1 trailing cable

Type 241.1 is specified for underground coal mining, where cable is reeled onto drums and trails behind continuous miners, shuttle cars, and other mobile mining equipment. Its crush-resistant, flexible construction makes it suited to the constant mechanical stress of this kind of duty — repeated flexing, dragging over rough ground, and the risk of being run over by heavy machinery — while its oil resistance and flame-retardant sheath suit the underground mining environment.

FAQ

What's the difference between Type 241.1 and general-purpose flexible cable? Type 241.1 is purpose-built to AS/NZS 1802 for underground coal mining, with a crush-resistant central cradle and heavy-duty sheath designed to survive being reeled, dragged, and run over by mining equipment — mechanical demands well beyond what a general-purpose flexible cable is built to handle.

What temperature range is Type 241.1 rated for? The cable is rated from -25°C to +90°C, reflecting both cold underground conditions and the heat generated under continuous load.

Why does the cable use tinned copper conductors? Tinning protects the copper conductors from corrosion, which matters given the wet, humid conditions typical of underground coal mining.
