TYPE A1, A2 & A3 Railway Signalling Cable

 

Applications :

  • The cables are designed for railway signalling systems. The cables are suitable for use in d.c. circuits where the nominal voltage to earth does not exceed 1100 volts and are suitable for installation in ducts.

Standards :

  • NR/PS/SIG/00005(formerly RT/E/PS/00005)
 

 

Construction :

  • Conductors : Tinned stranded copper, class 2 according to IEC 60228 & BS6360.
  • Insulation : LSZH crosslinked.
  • Core Wrapping : Plastic tape(s) with overlapping.
  • Sheath : LSZH (for types A2 & A3 only).

Electrical Characteristics at 20 °C :

  • Nominal Conductor Cross Section mm2 0.75 1.15
    Maximum Conductor DC Resistance Ω/km 24.8 17.3
    Voltage Rating KV 0.65/1.1
    Nominal Insulation Thickness mm 0.85 0.85

Mechanical and Thermal Properties :

  • Minimum Bending Radius : 6xOD (static); 15xOD (dynamic).
  • Operating Temperature : -25°C to +85°C (during operation) ; -10°C to +85°C (during installation).
