1-CHKE-V
APPLICATION
Cables substitute: 1-CYKY, NYM
Power cables with small cross section with higher resistance to fire propagation according to IEC 60332-3-22 (cat. A) and functional capacity by the fire for 180 minutes according to IEC 60331-23, non-halogen, with low smoke density by burning according to STN IEC 61034-2 and low corrosivity of combustion gases according to STN IEC 60754-2. Cables are designated for nominal voltage of 0,6/1 kV, for fixed installation in normal and wet ambient (STN 33 0300). Cables can be used also in environment with fire hazard and can be installed also on flammable base.
CONSTRUCTION
Pic. 1
1 Solid copper round core (cross section 1,5 ; 2,5 ; 4 mm2).
2 Fireproof barrier out of mica tape.
3 Conductor insulation is out of flame retardant non-halogen material. Number of conductors is 2 to 19. Colour marking of conductors responds to STN IEC 60446.
4 Braiding out of temperature resistant glass tape.
5 Flame retardant jacket, red colour with an option of labelling according to agreement.

DELIVERING, PACKING, STORAGE AND TRANSPORT
All cable types are supplied according to relevant company standards, twisted into coils, eventually greater lengths on wooden or metal drums. Every length is marked with tag with these data:
- producer´s mark
- cable identification
- cable length in meters
- production date
- stamp of quality control
The whole cable can be marked with description on a jacket on request of a client.
Cables can be stored in open-air area or in warehouses. They cannot be exposed to thermal radiation and they cannot be stored together with flammable liquids or solvents or with products containing them. It is safe to manipulate with cables at temperature range -10 °C až +50 °C.
It is necessary to assure that cables are not damaged by mechanical or other effects.
