Three Core 18/30kV Aluminium Conductor Power Cable – AL/XLPE/CWS/PVC to IEC 60502-2

Product Overview

The 18/30kV Three Core Aluminium Power Cable is a medium voltage (MV) energy cable designed for primary distribution networks. It features compact stranded aluminium conductor, XLPE insulation, copper wire screen (CWS), and PVC outer sheath – fully compliant with IEC 60502-2.

Ideal for utility grids, industrial substations, wind farms, and heavy infrastructure requiring reliable underground or aerial power transmission.

Frequently Asked Questions (FAQ)

Q: What is the difference between 18/30kV and 12/20kV?
A: 18/30kV indicates a higher insulation level – used for longer transmission distances and higher fault levels.

Q: Why copper wire screen (CWS) instead of copper tape?
A: CWS offers lower resistance, higher fault current capacity, and better flexibility. It also eliminates the need for separate earth conductor in many cases.

Q: Can this cable be directly buried?
A: Yes, standard PVC sheath is suitable for direct burial. Add armouring (AWA/SWA) for rocky soil or high mechanical stress.

Q: Is LSZH version available?
A: Yes – replace PVC sheath with LSZH (Low Smoke Zero Halogen) for tunnels or confined spaces.

Q: Does IEC 60502-2 require water blocking?
A: Not mandatory but highly recommended – available upon request (longitudinal water blocking tape).
