1 Class 5 flexible copper conductor, according to SR EN 60228
2 PVC insulation

In electrical installations, mounted on/in plaster in pipes for signaling or control circuits.

The conductors for the nominal voltage of 450/750 V can be used in protected installations (in pipes, electrical equipment, lighting fixtures, etc.) up to a voltage of 1000 V a.c. or up to 750 V d.c.

Mounting under plaster, embedded in concrete or under direct sunlight is not allowed.

Standard reference: SR EN 50525-2-31

Rated voltage:
Uo/U=300/500 V, for HO5V2-K, for 0,5 mm²÷ 1 mm²
Uo/U=450/750 V, for HO7V2-K, for 1,5 mm² ÷ 35 mm²
Minimum ambient temperature:
– during assembly: +5 °C
– during exploitation: -30 °C
Maximum allowable temperature on the conductor during normal exploitation: +90 °C 
Test voltage:

2 kV ; 50 Hz, 15 min, in water, for 0,5 mm² ÷ 1 mm²
2,5 kV ; 50 Hz, 15 min, in water, for 1,5 mm² ÷ 35 mm²

Insulated conductors have a flame propagation delay according to SR EN 60332-1-2
