Type 260 Mining Cable – 1.1kV to 11kV Armoured Power Cable – AS/NZS 1802 Compliant

Machinery & Equipment Mining Cables
Description

Product Overview

These heavy-duty armoured cables are specifically designed for demanding mining environments where superior mechanical protection and strength are essential. They are primarily utilized as feeder cables for power supply in mining operations, including connection to transportable mining substations and heavy machinery. Typical applications include sand mining and other extractive industries requiring robust, reliable power distribution under harsh conditions.

Key Standards Compliance:

  • AS/NZS 1802:2003

  • AS/NZS 1125

  • AS/NZS 3808

  • AS/NZS 5000.1

Construction Details

  1. Conductors (3×): Flexible stranded tinned annealed copper conductors for optimal flexibility and corrosion resistance.

  2. Conductor Screening:

    • 1.1/1.1kV: Polyester barrier tape.

    • 3.3/3.3kV and above: Polyester barrier tape plus extruded semiconductive tape.

  3. Insulation: EPR (Ethylene Propylene Rubber) - providing excellent electrical properties and thermal resistance.

  4. Insulation Screen: Semiconductive tape applied over insulation.

  5. Composite Screen (Earth Conductor): Tinned annealed copper braiding interwoven with polyester yarn, serving as both an earth conductor and electrical screen.

  6. Cradle Separator: Semiconductive PCP (Polychloroprene) filling to maintain core geometry and provide mechanical separation.

  7. Interstitial Pilots (3×): EPR insulated flexible stranded tinned copper conductors positioned in the interstices for control or monitoring functions.

  8. Inner Sheath: PCP (Polychloroprene) sheath providing bedding and environmental protection.

  9. Pliable Armour: Galvanized low carbon (mild) steel strands applied to provide robust mechanical protection while maintaining flexibility.

  10. Outer Sheath: Heavy duty PCP (Polychloroprene) sheath offering comprehensive protection against abrasion, moisture, and mining contaminants.
