Standard Overview
NF C 33-226 specifies requirements for insulated medium voltage aerial cables used in overhead distribution networks. The standard defines the construction, materials, electrical characteristics, and mechanical performance requirements for cables designed for medium voltage overhead power systems.
It is mainly applied in France and French-speaking regions, including many African markets, for medium voltage overhead distribution applications.
Key Requirements
Conductor: Stranded aluminum conductors
Insulation: XLPE (Cross-linked polyethylene) insulation
Screening: Metallic screen or conductive layers according to cable design
Construction: Insulated aerial conductors or bundled overhead cable systems
Voltage Rating: Commonly 12/20kV and 18/30kV
Performance: UV resistance, weather resistance, mechanical strength, and electrical reliability
Applications
Used for medium voltage overhead distribution networks, rural electrification, utility grids, and infrastructure projects.
