SXCAV & SXCAG Signalling Cables

 

Applications :

  • 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.

Electrical Characteristics at 20 °C :

  • Nominal Conductor Diameter mm 1.38
    Nominal Cross Section Area mm2 1.5
    Maximum Conductor Resistance (DC) Ω/km 12.3
    Minimum Insulation Resistance @500 V DC (3mins) MΩ.km 10000
    Maximum Mutual Capacitance @1000Hz (AC) nF/km 60
    Maximum Reduction Factor @170V/km 50Hz 0.24
    Operating Voltage V 1000

Mechanical and Thermal Properties :

  • Minimum Bending Radius : 10 x OD.
  • Temperature Range : -25°C to +90°C (during operation); -10°C +90°C (during installation).
