Abstract: Transmission line icing severely threatens grid security. Traditional steel-cored aluminum stranded conductors (ACSR) tend to form non-uniform ice accretion, exacerbating galloping risks. Low Wind-Pressure Conductors (LWPC) significantly reduce wind load via special aerodynamic structures (concave-arc/grooved structures), yet their icing characteristics remain unclear. This study systematically investigates ice distribution patterns on concave-arc and grooved LWPC using a thermodynamic-fluid dynamic Multiphysics coupling model. Twelve structural parameter combinations were designed (concave-arc radius: 9.15-16.90 mm; curvature radius: 2.45-5.00 mm; angle: 22.5-90°), with comparisons to traditional ACSR. Key findings include:(1) LWPC reduces ice mass per unit length by 19.88% (max 21.52%), peak ice thickness by 10.98%, and average thickness by 36.16%;(2) Comprehensive evaluation (uniformity coefficient, shape factor, non-uniformity coefficient) confirms significantly improved ice uniformity on LWPC;(3) Aerodynamic profiles regulate ice uniformity, providing an optimization basis for anti-galloping design. This study offers novel theoretical and engineering insights for ice-resistant and anti-galloping transmission lines. [ABSTRACT FROM AUTHOR]
