 POWER 1 kV CABLES
1-CXKE-R, 1-CHKE-R

Substitute: 1-CYKY, NYM

APPLICATION

Power cables with low cross section with low fire propagation according to IEC 60332-3A, 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

1. Copper round solid conductor
2. Core insulation from cross-linked polyethylene or on EVA co-polymer base
3. Flame retardant filling cover
4. Flame retardant polyethylene jacket, orange or black colour with description according to agreement
