SXCAV & SXCAG Signalling Cables

SXCAV & SXCAG Signalling Cables

Application

The cables are designed for connection between switching centers and equipment shelters along the trackside. The 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.
