These cables are used for power supplies with Protective Multiple Earthing (PME) systems, where a combined Protective Earth (PE) and Neutral (N) - together known as the PEN - connects the combined neutral-and-earth to real earth at multiple locations to reduce the risk of electric shock in the event of a broken PEN.

Construction of One Type Concentric Cable:

1- Phase conductor: Solid aluminum / copper conductor       2- Phase Insulation: XLPE / PVC        3- Pilot Core Conductor: Plain annealed copper wire       4- Pilot Core Insulation: PE (Poly Ethylene compounds)       5- Neutral Core: Solid aluminum conductor        6- Wraping tape       7- Ripcord       8- Outer sheath: PVC / PE

AIRDAC
Used for house connections. This cable can only be used for single phase supply. Cable is made to be suspended in the air. Cable is available as a Combined Neutral and Earth (CNE) and Separate Neutral and Earth (SNE) with coms wire available in Separate Neutral and Earth (SNE).
