1 Class 2 multifilar copper or aluminum conductor, according to SR EN 60228
2 PVC insulation
3 Copper strip screen
4 Internal PVC coating
5 Reinforcement of steel strips
6 PVC outer sheath

Intended for direct current supply of the contact network for urban electric transport (trolleybuses and trams)

Product standard: SF 4 – IPROEB
Nominal voltage: 1000 V
Minimum temperature of the cable (measured on the sheath):

– at assembly : +5 °C
– during operation : -33 °C

The maximum temperature of the conductor in normal operation: +70 °C
Conductor temperature in short-circuit mode with a maximum duration of 5 s: max. 160 °C.
Test voltage: 4 kV, 50 Hz, 5 min
The minimum radius of curvature when posing:

10 x the outer diameter of the unarmoured cable
15 x outer diameter of the reinforced cable

The cables are flame retarded according to SR EN 60332-1-2.
Cables which have F at the end have increased flame propagation delay according to SR EN 60332-3-24
