Cable code
- A-2Y (St) 2Y
Cable Layer Construction
- Cu/HDPE/OSCR/HDPE
Cable Structure
- Conductor material: Solid annealed conductor with smooth and uniform surface.
- PE core insulation: Compound of type Ill, class B, category 4 or 5 and grade EB according to ASTM D - 1248
- Core identification: The single cores are twisted together to form a pair; pairs are color coded and twisted pairs form the cable core.
- Core wrapping: A layer of polyester film wrapped helically or longitudinally for core protection.
- Aluminium shield: A layer of aluminium foil wrapped helically or longitudinally as a shield in contact with a single tinned copper wire.
- PE outer sheath: Compound of type Ill, class B, category 4 or 5 and grade J3, according to ASTM D - 1248.
- Sheath color is black
Application
All outdoor cables are principally suitable for installation in most types of plants.
Cables with an outer sheath of polyethylene without adequate protective measures should not be used in plants with fire explosion hazards.
None of these cables are suitable for power installation purposes and are mainly operated at low frequencies and only in the circuits. Also, they are used as primary and secondary cables in local telephone networks, as railway communication cables and in industrial plants.
