The core is encapsulated in a fiberglass\/epoxy sheath for added protection and is surrounded by trapezoidal or round strands of fully annealed, high-purity aluminum (up to 62.5% IACS conductivity).<\/p>\n<p dir=\"auto\">This design allows continuous operation at <strong>180\u2013200\u00b0C<\/strong> with minimal thermal expansion, enabling utilities to double power transfer capacity on existing rights-of-way without major tower modifications.<\/p>\n<h3 dir=\"auto\">Principaux avantages des conducteurs ACCC<\/h3>\n<ul dir=\"auto\">\n<li><strong>Ampacit\u00e9 exceptionnelle<\/strong> \u2014 Safe continuous operation at 180\u2013200\u00b0C provides up to <strong>twice the current-carrying capacity<\/strong> of equivalent ACSR conductors at the same sag limit.<\/li>\n<li><strong>Performances de tr\u00e8s faible affaissement<\/strong> \u2014 The carbon fiber core has an extremely low coefficient of thermal expansion above the knee-point temperature, allowing longer spans and reduced tower heights or reinforcements.<\/li>\n<li><strong>L\u00e9ger et haute r\u00e9sistance<\/strong> \u2014 The composite core is approximately <strong>70% lighter<\/strong> than steel while offering superior tensile strength, enabling <strong>28\u201330% more aluminum<\/strong> content for better conductivity without increasing conductor weight or diameter.<\/li>\n<li><strong>R\u00e9duction des pertes \u00e9lectriques<\/strong> \u2014 Higher aluminum content and optimized trapezoidal stranding deliver <strong>25\u201340% lower DC resistance<\/strong> and line losses compared to ACSR.<\/li>\n<li><strong>r\u00e9sistance sup\u00e9rieure \u00e0 la corrosion<\/strong> \u2014 Ideal for coastal, mining, industrial, and heavily polluted environments where steel-core conductors suffer accelerated corrosion.<\/li>\n<li><strong>Excellente stabilit\u00e9 thermique et faible fluage<\/strong> \u2014 Minimal relaxation and long-term mechanical reliability under high temperatures and dynamic loads.<\/li>\n<\/ul>\n<h3 dir=\"auto\">Principales applications<\/h3>\n<p dir=\"auto\">ACCC conductors are the preferred choice for:<\/p>\n<ul dir=\"auto\">\n<li>Augmentation de la capacit\u00e9 des lignes de transport existantes sans modification des pyl\u00f4nes<\/li>\n<li>Nouvelles lignes a\u00e9riennes \u00e0 haute tension
