NF C 33-226 Hta Cis 12/20kv 3X240mm Mv Cable The NF C 33-226 Hta Cis 12/20kV 3x240mm medium-voltage (MV) cable stands as a pinnacle of reliability in power distribution, engineered to bridge high-voltage grids and local networks. Compliant with France’s stringent NF C 33-226 standard, this cable operates at 12/20kV and features a 3x240mm configuration, balancing robust power capacity with structural efficiency.
At its core, three 240mm² conductors—crafted from high-purity copper or aluminum—ensure efficient current transmission. Copper offers superior conductivity for minimal energy loss, while aluminum reduces weight, easing installation in long-span scenarios. Stranded for Flexibility, these conductors resist oxidation via protective coatings, ensuring longevity in harsh environments. Surrounding each conductor, cross-linked polyethylene (XLPE) insulation delivers exceptional dielectric strength, withstanding 12/20kV voltages and temperatures up to 90°C continuously (130°C for short overloads). Semiconductive layers (inner and outer) ensure uniform electric field distribution, preventing insulation breakdown. A metallic screen—copper tape or braid—provides earthing for fault currents and shields against electromagnetic interference. The outer sheath, made from PVC, PE, or halogen-free materials, defends against moisture, chemicals, and UV radiation, adapting to diverse installation needs.
With an ampacity of 400–600A, this cable serves urban grids, rural electrification, industrial facilities, and renewable energy projects. Its compliance with IEC 60502 and national standards (e.g., BS 6622, DIN VDE 0276) ensures global 适用性. Whether underground, overhead, or in ducts, it combines durability, efficiency, and safety, making it indispensable for modern medium-voltage networks.
