Type 450 Flexible Copper Screened Mining Cable With Two Earth And One Pilot Core

Type 450 cables are available as 3+2+1 – 3 Core plus 2 Earth Cores and 1 Pilot core configurations – and in a range of conductor cross sectional area sizes. As with many mining industry cables, the pilot core is principally to provide support and reinforcement but allows for the possibility of additional monitoring if this too has a current applied.
