A 16mm 5-core flex cable contains five copper conductors, each with a cross-sectional area of 16mm2. These cores are insulated and enclosed in a flexible outer sheath (usually PVC or rubber), making the cable easy to bend and install.
Construction
* Conductors: Stranded pure copper (for high conductivity and flexibility)
* Number of cores: 5 cores (typically Red, Yellow, Blue, Black, and Green/Yellow for earth)
* Insulation: PVC or rubber insulation for each core
* Outer sheath: Tough flexible PVC or rubber
* Voltage rating: Commonly around 450/750V or 600/1000V
Features
Highly flexible – suitable for bending and movement
* High current carrying capacity (due to 16mm thickness)
* Strong insulation for safety
Applications in Nigeria
* 3-phase power supply systems
* Generator and changeover connections
* Industrial machines and equipment
