Railway Cables

Application

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℃

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**
