Standard: SRPS N.C3.230
Nominal voltage: 380 V
Test voltage: 2,0 kV
CONSTRUCTION
Conductor: annealed copper wire class 1,
according to SRPS N.C0.015, IEC 60228.
Insulation: PVC compound, PI1 according to SRPS N.C0.195.
Colour code: according to HD 308 S2;
VDE 0293-308
Sheath: PVC compound layer over 2 or 3
cores, which are laid parallel. The layer is
forming the track between the cores, with the
notch in the middle of the track, this making
possible temporary fixing of the cables.
Sheath colour can be white, grey or black.
Behaviour in fire: IEC 60332-1
APPLICATION
In dry conditions indoors, for laying in plaster
or under plaster, without special mechanical
protection.
Suitable for installations in objects
made of prestressed concrete, vibrated concrete or prefabricated elements, when the notches for laying the round cables can not be made.
Not for use in wooden object, nor in open air.
Permissible conductor temperature:
– max operating temperature +70°C,
– in short circuit (max 5 s), max +160°C.
Permissible environment temperature:
at laying and handling, min +5°C.
BENDING RADIUS (min.):
Smallest bending radius for permanently laid cable: 4a (a – hight of cable).
