NFC 33-209 Aerial Bundle Conductor ABC Cable 3×25+54.6 mm²
NFC 33-209 Aerial Bundle Conductor ABC Cable 3×25+54.6 mm² is a 0.6/1 kV low-voltage aerial bundled cable for overhead distribution networks. The configuration consists of three 25 mm² compacted stranded aluminium phase conductors twisted around one 54.6 mm² aluminium alloy neutral messenger.
The 54.6 mm² neutral messenger functions as both the neutral conductor and the self-supporting mechanical element. All cores are insulated with black, weather-resistant XLPE and assembled as a pre-twisted overhead bundle for residential, rural and utility distribution projects.

Key Features
3×25+54.6 Correct Configuration
Three 25 mm² aluminium phase conductors are combined with one 54.6 mm² aluminium alloy neutral messenger.
Self-Supporting Neutral Messenger
The 54.6 mm² neutral conductor carries the mechanical tension of the aerial bundle, reducing the need for a separate catenary wire.
XLPE UV Protection
Black weather-resistant XLPE insulation is designed for outdoor exposure and a 90°C maximum continuous conductor temperature.
Preassembled Twist Bundle
The four insulated conductors are supplied as one twisted bundle for efficient overhead installation and organized phase arrangement.
Low-Voltage Distribution
The 0.6/1 kV design is intended for overhead residential, rural and utility distribution networks.
Reduced Phase-to-Phase Exposure
Individual insulation around the bundled conductors improves protection against accidental contact and wind-induced conductor faults.
Construction & Standards
Construction Sequence
Each 25 mm² phase conductor is made from compacted stranded aluminium and insulated with black UV-resistant XLPE. The 54.6 mm² aluminium alloy messenger is insulated and laid together with the three phase cores in a twisted preassembled bundle.
Messenger Function
The neutral messenger provides the neutral electrical path and the mechanical supporting element. Its reference minimum breaking strength is 1,660 daN for the 54.6 mm² construction.
Applicable Standard
NF C 33-209 applies to low-voltage aerial bundled conductors used for overhead distribution networks. Final approval markings, conductor properties, dimensions and test documentation depend on the ordered production design.
