Substitute: NCYKY, NCYKFY,NCEY, NCEFY
APPLICATION
Signal cables with low fire propagation according to IEC 60332-3A, halogen-free, with minimum smoke formation by burning according to IEC 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 0,3/0,5 kV for fixed and free installation in normal and wet surroundings (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 conductor - solid or stranded.
2. Core insulation from cross-linked polyethylene or on EVA co-polymer base. Cores are stranded together.
3. Wrapping with Al-PET tape and tinned copper wires (for type CXFE and CHFE only).
4. Flame retardant filling cover.
5. Flame retardant polyethylene jacket, orange colour with description according to agreement.
