Type 209 Mining Cable

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.

Technical Specifications

Cable Construction

1. Conductor: Tinned annealed copper wires provide a flexible current path for mobile and trailing mining equipment.
2. Separator / Screen: Type 209.1 uses a paper separator, while higher voltage versions use semi-conductive thermosetting compound.
3. Insulation: EPR type R-EP-90 insulation provides thermal and electrical stability for flexible mining service.
4. Insulation Screen: Type 209.1 uses synthetic tape; Type 209.3 and above use semi-conductive thermosetting compound.
5. Screen: Tinned copper/polyamide braid supports screened operation in mining power circuits.
6. Central Pilot Core: Flexible stranded tinned copper pilot core with EPR covering for control or monitoring functions.
7. Cable Assembly: Three screened power cores are laid up with right-hand direction on a cradle separator around the central pilot core.
8. Cradle Separator: Semi-conductive thermosetting compound helps maintain the cable geometry and electrical design.
9. Outer Sheath: Black PCP thermosetting compound HD-85-PCP provides extra heavy-duty protection, oil resistance and flame retardance.

Standards and Compliance

Dimensions and Electrical Data

Final cable size should be selected according to equipment current, voltage drop, installation length, permissible drum diameter, operating temperature and the required mining documentation package.

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.
