摘　　要：Ice accumulation of overhead transmission lines can lead to serious damage to power systems.Superhydrophobic nanostructured Al conductors are proposed to replace the de-icing or ice-melting equipment for economic advantages,good anti-icing properties and robust electrical performance.Anodisation under different direct current densities is adopted to fabricate two nanostructures on Al conductors,including the reticular and honeycomb-like nanoporous structures.Compared to pure Al conductors,the anodised surface of honeycomb-like nanoporous structures exhibits lower ice adhesion(3.82 kPa)and ice accumulation.Aluminium conductor steel reinforced treated in the proposed method has also been validated to exhibit a significant anti-glaze icing property.Addi-tionally,corona performance and line loss are experimentally measured and calculated to prove good electrical performance.The 0.27 A Al strand shows the highest corona inception voltage(27.86 kV)and the lowest AC resistance(4.65Ω/km),which is attributed to the good dielectric property and heat dissipation.Therefore,the proposed anti-icing transmission conductors show profound application potential for power systems.
