1 Class 1 or class 2 copper conductor, according to SR EN 60228
2 Cross-linked polyethylene insulation (XLPE) type 2XI1, according to SR HD 604
3 Extruded or bandaged inner cover
4 Inner sheath without halogens
5 Galvanized (Abz) or ungalvanized (Ab) steel strip reinforcement
6 Outer sheath of thermoplastic polyethylene with low 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, airports, metro stations, supermarkets, theaters, hospitals, etc.
When burning, the cables do not release toxic and corrosive gases and have low smoke emission.

Product standard: SF 46 IPROEB
Standard reference: SR HD 604
Nominal tension: Uo/U(Um) = 0,6/1 (1,2) kV
Minimum cable temperature (measured on the sheath):

– at assembly : -5 °C
– during exploitation: -40 °C

The maximum temperature allowed on the conductor, under normal operating conditions:

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

Test voltage: 4kV, 50 Hz, 5 min
Behavior when burning:
The cables have an increased flame propagation delay, according to SR EN 60332-3-24.
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 bonding:

15 x outer diameter, for cables with one conductor
12 x outer diameter, for multiconductor cables

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).
