Trackside Signalling Aluminium Power Cables to BR880

 

Applications :

  • BR880 solid sector shaped conductors for trackside signalling power supplies.

Standards :

  • BR880
  • BS 5467
  • BS 6346
  • UNE 21123
 

 

Construction :

  • Conductors : Sector shaped solid plain aluminium to IEC 60228 class 2 or 5.
  • Insulation : XLPE type GP8 to BS 7655 or PVC type TI 1 to BS 7655.
  • Core Wrapping : PETP (Pol yethy lene Terephthalate).
  • Sheath : PVC type 9 to BS 7655 (LSZH can be offered as an option).

Electrical Characteristics at 20 °C :

  • Nominal Conductor Cross Section mm² 16 25 35 50 70 95
    Maximum DC Conductor Resistance Ω/km 1.91* 1.2* 0.868* 0.641 0.443 0.32**
    Voltage Rating KV 0.6/1
  • * Aluminium conductors 10mm² to 35mm² circular only.
    ** For single core cables, four sectoral shaped conductors may be assembled info a single circular conductor. The maximum resistance of the assembled conductor shall be 25% of that of the individual component conductors.
