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 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 : EPR Type GP4 to BS7655.
• Core Wrapping : Plastic tape(s) with overlapping.
• Sheath : HDPCP Type RS2 to BS7655.

Electrical Characteristics at 20 °C :

• Nominal Conductor Cross Section	mm²	0.75	1.5	2.5	10.0	16.0	35.0	70.0	95
  Maximum Conductor DC Resistance	Ω/km	24.8	12.2	7.56	1.84	1.16	0.529	0.27	0.195
  Voltage Rating	KV	0.65/1.1
  Nominal Insulation Thickness	mm	0.85	0.8	0.8	1.0	1.0	1.2	1.4	1.6

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).
