RAILSIG Railway Signalling & Control Cables
EAPSP n×1×1.4
Application
EAPSP n×1×1.4 cables are used as railway cables and can be installed directly into the ground or in ducts.
Construction
Conductors: Soft annealed solid copper, 1.4 mm nominal diameter.
Insulation: PE insulation.
Stranding: Cores are helically stranded in concentric layers.
Core Wrapping: Plastic tape(s) with overlapping.
Moisture Barrier: One laminated sheath made of aluminium tape (0.2mm thick) coated with copolymer on at
least one side is applied longitudinally with overlap.
Inner Sheath: PE sheath.
Armour: One corrugated steel tape is longitudinally applied with overlap.
Outer Sheath: PE sheath.
