Application:

The Type 440 (1.1kV to 22kV) Mining cable is primarily utilized as a Flexible Feeder Trailing Cable for providing power to heavy machinery and equipment. Its design, including three large pilot cores and a central semi-conductive cradle for core support and protection, makes it exceptionally suitable for demanding environments.

Construction:

3×Conductors: Flexible stranded tinned annealed copper conductor

Conductor Screen: Semi-conductive compound (for cables voltage≥3.3/3.3kV ).

Insulation: EPR

Insulation Screen: Semi-conductive elastomer

Composite Screen (earth conductor): Tinned annealed copper braiding interwove with polyester yarn

Cradle Separator: Semi-conductive PCP

3×Interstitial Pilot: EPR covered flexible stranded tinned copper conductor

Sheath: Heavy duty PCP sheath. (Heavy duty CPE/CSP sheath optional)
