1 Single-wire class 1 or multi-wire class 2 light copper conductor according to SR EN 60228
2 Cross-linked polyethylene (XLPE) type 2XI1 insulation according to SR HD 604
3 Aluminum wire reinforcement
4 Outer sheath of thermoplastic polyethylene with low emission of smoke and corrosive gases (LSFH) type HM4 according to SR HD 604, black color

Halogen-free cables are intended for fixed direct current electrical installations where increased protection is provided in case of fire.
When burning, the cables do not release toxic and corrosive gases and have low smoke emission.
It is not allowed to screen them in water or directly on the ground, but only in protective tubes.

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):

– during assembly: – 5 °C
– during operation: – 40 °C

Maximum temperature allowed on the conductor:

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

Test voltage: 4 kV 50 Hz, 5 min
Bonding radius: 15 x outer diameter
Pulling strength at screening:

max. 30 N/mm² of aluminum conductor section
max. 50 N/mm² of copper conductor section

The cables have an increased flame propagation delay: they correspond to the compliant fire test 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 permeability: ≥60
Semnificatie simbol conductor:

ru – single-wire round conductor (class 1)
rm – multi-core round conductor (class 2)
