1 Copper or aluminum single-wire class 1 or multi-wire class 2 conductor, according to SR EN 60228
2 PVC insulation
3 Extruded or banded joint sheathing
4 Reinforcement of galvanized (Abz) or ungalvanized (Ab) steel strips
5 PVC outer sheath

The cables are intended for the use of electricity in fixed electrical installations.
Cables reinforced with a conductor are not intended for use in alternating current.

Product standard: SF 9 IPROEB
Standard reference: SR CEI 60502-1
Rated voltage: Uo/U (Um) = 0,6/1 (1,2) kV
Minimum temperature of the cable (measured on the sheath):

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

The maximum temperature allowed on the conductor under normal operating conditions: +70 °C
Test voltage: 3,5 kV, 50 Hz, 5 min
Minimum bending radius during installation:

15 x cable diameter with one conductor
12 x cable diameter with more conductors

The cables are flame retarded according to SR EN 60332-1-2
Cables which have F symbol have increased propagation delay according to SR EN 60332-3-24.
Meaning of conductor symbols:

ru – single-core round conductor (class 1)
rm – multi-core round conductor (class 2)
su – single-core sector conductor (class 1)
sm – multi-core sector conductor (class 2)

On request, cables with flexible copper conductors (class 5) can be made
