About 16 Sq mm 4 Core Aluminium Armoured Cable
The 16 Sq mm 4 Core Aluminium Armoured Cable is a heavy-duty power cable widely used for low-tension (LT) industrial, commercial, and residential underground power distribution. It is typically rated for voltages up to 1100V and features a current-carrying capacity of approximately 50 to 73 Amperes, depending on installation conditions.
- Conductor: High-grade stranded aluminium for lightweight efficiency.
- Insulation: Most variants use XLPE (Cross-linked Polyethylene) for high thermal resistance and dielectric strength, though some PVC-insulated options exist.
- Armouring: Provides mechanical protection via galvanised steel wire or flat strip.
- Sheathing: Outer layer is usually PVC Type ST-2, often available in Fire Retardant Low Smoke (FRLS) variants for enhanced safety.
- Current Rating: Approximately 73 Amps when laid directly in the ground and 70 Amps in the air.
