A 6mm2 3-core armoured cable (Kabelmetal type) is a strong, heavy-duty electrical cable designed for safe power distribution, especially where mechanical protection is required.
This cable consists of three insulated copper conductors, each with a 6mm2 cross-sectional area, enclosed in protective layers including steel armouring.
Construction
1. Conductors
• 3 cores (Live, Neutral, Earth or 3-phase lines)
• Made of pure copper for high conductivity
2. Insulation
• Usually PVC or XLPE
• Protects each core from electrical leakage
3. Bedding Layer
• Inner sheath that holds the cores together
4. Armouring (SWA – Steel Wire Armour)
• Provides mechanical protection against damage
• Makes it suitable for underground or outdoor use
5. Outer Sheath
• PVC covering for protection against moisture, chemicals, and weather
