Description

Description

Construction

  • Heavy Duty CPE sheath
  • EPR insulated and composite braid (earth) screened power conductors
  • EPR insulated and composite braid screened pilot/control cores
  • Centre filler

Cables to AS/NZS 1972:2006

The armoured high voltage, feeder and machine cables manufactured to AS/NZS 1972 are primarily designed for use in specific applications in underground coal mines but many of these are suitable for other above ground or general mining applications. Cables dsigned for single point suspension are also available.
