Construction :

  • Conductors : Tinned stranded copper, class 5 according to IEC 60228 & BS6360.
  • Insulation : LSZH or EPR Type GP4 to BS7655.
  • Outer Sheath : LSZH.

Electrical Characteristics at 20 °C :

  • Nominal Conductor Cross Section mm2 2.5
    Maximum DC Conductor Resistance Ω/km 8.21
    Voltage Rating KV 0.65/1.1
    Nominal Insulation Thickness mm 1.05

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).
