Application
NF2X cables are self-supporting bundled conductors designed for low-voltage overhead power distribution. They are commonly used in metropolitan, suburban, and rural networks for:
-
Public street lighting
-
House service connections
-
Power distribution from pillars, wall-mounted brackets, and building facades
The cable is suitable for installation directly on poles, facades, or consoles, offering a neat and secure solution in densely populated or difficult terrain areas.
Standards and Designation
-
HD 626 S1
-
VDE 0276-626
Cable Code Explanation:
-
N – Standard power cable
-
F – Facade application
-
2X – XLPE (cross-linked polyethylene) insulation
-
+N – With a messenger core for self-supporting installation
-
A – Aluminum conductor (when specified)
All sizes use round stranded conductors, providing flexibility and consistent electrical performance for low-voltage connections.
