1. Conductors:
* Each core has a 25mm2 cross-sectional area for carrying moderate to high current
2. Insulation:
* Usually PVC or XLPE
* Prevents electrical leakage and withstands heat
3. Inner Bedding:
* PVC layer that binds and protects the cores
* Provides protection against damage, pressure, and rodents
