1 Class 1 or class 2 copper conductor, according to SR EN 60228
2 Thermoplastic polyethylene insulation with low emission of smoke and corrosive gases (LSFH)
3 Inner cover
4 Inner sheath without halogens
5 Steel strip reinforcement galvanized (Abz) or ungalvanized (Ab)
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 105 IPROEB
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: +70 °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
The corrosivity of the gases released during combustion, according to SR EN 60754-2:

– pH ≥ 4,3
– conductivity ≤100µS.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

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