SXCAV & SXCAG Signalling Cables
Application
SXCAV & SXCAG Signalling Cables are designed for connection between switching centers and equipment
shelters along the trackside.
SXCAV & SXCAG Signalling Cables are used as main signalling cables specially designed to give good induction
protection (R.F=0.24 at inductive voltage 170 V/km) and are suitable for installation in intercity railways electrifi
ed at 25KV ac.
Standards
SXCAV SXCAG Specifi cation
Fire performance: EN 50266-2-4 C
Construction
Conductors: Class 1 solid bare copper conductor.
Insulation: Coloured cross-linked PE insulation.
Cabling Element: Each two conductors are twisted together to form a pair.
Stranding: Pairs are helically stranded in layers to form the cable core.
Core Wrapping: Plastic tape(s) with overlapping.
Inner Sheath: PE sheath.
Electrostatic Shield: One corrugated copper tape.
Intermediate Sheath: PE sheath.
Electromagnetic Shield: Two helically applied steel tapes.
Outer Sheath: Black unleaded PVC (SXCAV) or green halogen free (SXCAG) sheath.
