Type 209 Mining Cable for Mining Machinery
Type 209 flexible copper screened mining cable is a heavy-duty power cable for mining machinery, mobile feeder circuits and trailing equipment operating from 1.1kV up to 11kV. Its construction combines tinned copper conductors, EPR insulation, copper/polyamide screening and a PCP outer sheath, giving engineers a practical cable choice for equipment that needs both flexibility and protection in demanding mining environments.
Key Engineering Features
- Multiple voltage grades: Type 209.1, 209.3, 209.6 and 209.11 cover 1.1kV, 3.3kV, 6.6kV and 11kV systems, allowing one cable family to support different mining machinery supply levels.
- Flexible tinned copper conductors: Tinned annealed copper wires help maintain conductivity while improving resistance to corrosion in damp or chemically exposed mining areas.
- EPR insulation: Ethylene propylene rubber insulation supports stable electrical performance across the rated temperature range and is well suited to flexible power cable designs.
- Copper/polyamide braid screen: The screened construction helps manage electrical stress and supports safer operation around mobile mining equipment.
- Central pilot core: The EPR-covered flexible stranded tinned copper pilot core supports monitoring and control circuits commonly used in mining equipment systems.
- Heavy-duty PCP sheath: The PCP sheath is selected for oil resistance, flame retardance and extra heavy-duty protection against abrasion and rough handling.
- Weather and site resistance: The cable is designed for exposure to water, UV, sunlight, ozone and oil, making it suitable for harsh surface and underground operating conditions.

Cable Construction
- Conductor: Tinned annealed copper wires provide a flexible current path for mobile and trailing mining equipment.
- Separator / Screen: Type 209.1 uses a paper separator, while higher voltage versions use semi-conductive thermosetting compound.
- Insulation: EPR type R-EP-90 insulation provides thermal and electrical stability for flexible mining service.
- Insulation Screen: Type 209.1 uses synthetic tape; Type 209.3 and above use semi-conductive thermosetting compound.
- Screen: Tinned copper/polyamide braid supports screened operation in mining power circuits.
- Central Pilot Core: Flexible stranded tinned copper pilot core with EPR covering for control or monitoring functions.
- Cable Assembly: Three screened power cores are laid up with right-hand direction on a cradle separator around the central pilot core.
- Cradle Separator: Semi-conductive thermosetting compound helps maintain the cable geometry and electrical design.
- Outer Sheath: Black PCP thermosetting compound HD-85-PCP provides extra heavy-duty protection, oil resistance and flame retardance.
Applications
- Flexible feeder cable for mining machinery.
- Trailing cable for mobile mining equipment.
- Power supply cable for drills and hand-held tools in smaller sizes.
- Industrial machinery operating in oil, water, UV, ozone or abrasive environments.
- Mining power distribution where screened flexible cable construction is required.
