A 16mm2 4-core flexible cable (flex) is a medium-duty electrical cable designed for supplying power where flexibility and easy movement are required.
⸻
Description
A 16mm 4-core flex contains four flexible copper conductors, each with a cross-sectional area of 16mm2. It is commonly used for 3-phase power systems with neutral.
Construction (Structure)
1. Conductor (Core):
• Made of fine-stranded copper wires
• Highly flexible (unlike rigid cables)
• 4 cores (3 phase + 1 neutral)
2. Insulation:
• Usually PVC (Polyvinyl Chloride) or rubber
• Each core is insulated separately
Key Features
• Flexible and easy to bend
• Voltage rating: typically 450/750V or 0.6/1kV
• Current carrying capacity: about 60–80 Amps (depends on installation)
• Good resistance to wear and environmental conditions
