1 Class 1 or class 2 copper conductor according to SR EN 60228
2 Reticulated polyethylene insulation type 2XI1, according to SR HD 604
3 Halogen-free taped internal coating
4 Concentric conductor of copper wires and copper strip
5 Halogen-free thermoplastic inner sheath
6 Round galvanized steel wire reinforcement
7 Thermoplastic polyethylene jacket with reduced emission of smoke and corrosive gases (LSFH) type HM4, according to SR HD 604

The cables are intended for fixed electrical installations in power plants, in public buildings, train stations, metro stations, supermarkets, theaters, hospitals, etc.
When burning, the cables do not release toxic and corrosive gases and have low smoke emission.
Cables can be installed in wet places, but not directly in water or in the ground.

Product standard: SF 46 IPROEB
Standard reference: SR HD 604
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: -40 °C

Maximum temperature allowed on the conductor:

- under normal operating conditions: +90 °C
– during short circuit (max. 5 s): 250 °C

Test voltage: 4 kV, 50 Hz, 5 min.
Behavior when burning:
The cables have an increased flame propagation delay, according to SR EN 60332-3-24 si SR EN 60332-1-2.
The corrosivity of the gases released during combustion, according to SR EN 60754-2:

– pH ≥ 4,3
– conductivity ≤ 100 µS.cm-1

Smoke density according to SR EN 61034: – light transmission ≥ 60%
Minimum radius of curvature: 12 x outer diameter
Meaning of conductor symbols:

ru – single-wire round conductor (class 1);
rm – multi-wired round conductor (class 2);
sm – multi-wired sector conductor (class 2).
