1-CHKE-V

POWER 0,6/1 kV CABLES
functional during fire 1-CHKE-V

Substitute: 1-CYKY, NYM

APPLICATION

Power cables with low cross section with low fire propagation according to IEC 60332-24 (cat. C), functional during fire up to 180 minutes according to IEC 60331-21, halogen-free, with minimum smoke formation by burning according to EC 61 034 and low smoke corrosivity by IEC 60 754. They have copper conductors with insulation and jacket from halogen-free materials. Cables are dedicated for nominal voltage 0,6/1 kV for fixed installation in normal and wet ambient (STN 33 0300). Cables may be used also in surrounding with fire danger and they may be installed on flammable base.

CONSTRUCTION

Copper round solid conductor.
Fire-fighting barrier from mica tape.
Core insulation from fire retardant non-halogen material. Number of coresl - 2 to 7. Insulation color according to
IEC 60446.
Wraparound from thermal resistant glass tape.
Flame retardant polyethylene jacket, orange colour with description according to agreement.
